Car Cranks but Wont Start

Car Cranks but Wont Start

The car cranks but won’t start. The possible reason why car cranks but won’t start are  out of gas, broken timing belt, clogged air filter, battery is weak or frozen battery electrolytes.

Out of Gas

When the car cranks faster than normal then it is possible that the car is out of gas, therefore during cranking observe if the car will crank faster than normal then check if the car has fuel. Just fill the car with enough fuel and crank again.

Broken Timing Belt

If the car has enough fuel then the possible problem is that the car timing belt is broken. The broken timing belt can cause the engine compression to become low and since the car has low compression it is the reason why the engine cranks but won’t start. Timing belt ensures the engine valve to close during the combustion of each engine cylinder when the belt is broken there will be no compression in each cylinder thus the car won’t start during cranking.

Car Cranks but Wont Start

Bring the car to a reputable car shop and ask the mechanic to check the timing belt to confirm if it is indeed broken, if the mechanic confirms the broken timing belt then have it replaced.

Clogged Air Filter
If the car cranks normally or is the same as when the car is about to start then the possible problem is a clogged air filter. The clogged air filter is the reason why the car cranks but won’t start because when the air filter is clogged there is not enough air going into the engine, the air filter becomes clogged because of too much dirt in the element, this dirt is preventing the air to go inside the combustion chamber. Since there is not enough air inside the cylinder then it will not start because air is one of the components necessary for combustion.

Now, start the car and observe if the engine cranks the same as when it is about to start. Open the hood and locate the air filter. Removed the air filter then clean it, usually to clean the air filter just spray a pressurized air on the element. Cleaning the air filter is just a temporary solution to the problem.

The permanent solution is to replace the air filter. Normally air filter is replaced every two years, therefore, verify if the air filter installed on your car is past the two years period.

Car Battery is Weak or Battery Terminal is Corroded
If the car cranks slower than normal then the possible problem is a weak battery or the battery terminal is corroded. When the battery is weak there is not enough power to crank the engine, however, if the terminal is corroded then the current that flows into the starter is not enough to start the engine because the corrosion interferes on the flow of current.
Check the car battery.

Car Turns Over but Won't Start

The car turns over but won't start. The car is cranking slowly however, it will not start. If the car is turning over slowly and will not start the possible reason is the battery.

Read more : Car Turns Over but Won't Start

Do the simple test to check if the battery is weak

1. Turn ON the headlights then turn the ignition key to start the engine while the headlights are ON.
2. During cranking observed if the brightness of the headlights changes, if the brightness changes when the engine is crank then there is a problem with the battery.

Now open the hood and locate the battery. Look thoroughly at the battery terminal for any corrosion present on the terminal. If the terminal is corroded then it is the reason why the car won’t start.

Clean the terminal with a wire brush. Apply a baking soda mix with water into the terminal before brushing with a wire brush. Also after the cleaning apply petroleum jelly on the battery terminal to prevent the terminal from corroding in the future.

However, if the terminal is not corroded then the battery is weak. Now, look at the fluid level of the battery, remove the fluid filler cap and check if the battery fluid covers the top of the battery plate, if not then add distilled water on the battery. The distilled water must cover the top of the battery plate then jump start the car to start the engine.

How to Jump Start a Car Battery

Jump starting a car is easy but should be done correctly so that accidents such as a battery explosion can be avoided.

Read more : How to Jump Start a Car Battery

However, if the battery has enough battery fluid then you have no other choice but to replace the battery with a new one.

Frozen Battery Electrolytes
If the car cranks but won’t start only when the temperature is very cold then the problem is a frozen battery electrolyte. At a very cold temperature, the electrolytes inside the battery may freeze or partially freeze, if this happens the battery will lose its power and it will not start the engine.

Let the battery get warm for a while before starting the car. Now if you are about to drives on a very cold region use a battery with a higher cold cranking rating.

Honda Civic Won’t Start Makes Clicking Noise

Honda Civic Won’t Start

Does your Honda Civic won’t start, makes clicking noise during starting? Since the engine is not starting there are two possible reasons why your honda civic is not starting, clicking noise that is heard during starting is because of the solenoid from the stater. The solenoid is the one that allows the current from the battery to flow into the starter to make the engine crank. With that said the possible cause of the problem is a weak battery or the starter is failing.

Squealing Noise on Brakes

The brakes produce squealing noise during braking this is because of two possible reasons, first is the noise comes from the brake pad wear indicator and the second is because of the high-frequency vibration.

Black Smoke from Exhaust of Car

Black smoke from the exhaust of the car comes out while driving. The possible reasons for black smoke from the exhaust is a clogged air filter, bad fuel injector sensor (throttle position sensor, coolant temperature sensor, and mass airflow sensor).

Clogged air filter

Black smoke that comes out the exhaust is an indication of too much gas burned inside the engine combustion chamber. The most common reason why there is black smoke from the exhaust is the clogged air filter. When the air filter is clogged, enough amount of air will be restricted from going inside the engine making the air/fuel to become reach (too much fuel with not enough air).

Black Smoke from Exhaust of Car

White Smoke from Exhaust - Diesel Engine

If you notice the white smoke even if the engine has warmed up, then it is a problem and usually it is a blown head gasket that causing it.

Read more : White Smoke from Exhaust - Diesel Engine

Open the hood of the car and locate the air filter, refer to the manual covering the vehicle model if you have difficulties finding the air filter. Remove the air filter and examine closely if there is too much dirt present on the filter, if there is too much dirt then this is what restricting replacement parts from going inside the combustion chamber that is why the air is insufficient and the fuel is too much.

Replace the air filter. This should fix the problem. Any auto parts have an air filter for their inventory so nothing to worry about where to find replacement parts.

Bad Fuel Injector Sensor

This problem is only possible for cars with fuel injection system. Usually, the problem for this system is the electronic sensors that measure various engine factors which the car computer system is used for calculating the amount of fuel that must be injected on each engine cylinder. If one the sensors are faulty then wrong data will be sent to the car computer and the air/fuel mixture will be wrong which in this case the fuel is too rich.

There are three sensors that when faulty can cause black smoke, the sensors are throttle position sensor, engine coolant temperature sensor, and the mass airflow sensor.

Throttle Position Sensor

Engine Coolant Temperature Sensor

Mass Airflow Sensor

There is only one way to determine if the sensor is faulty, this is to hook up the car to an engine analyzer. The engine analyzer will display trouble codes which can be used to determine if the sensor is the problem. With that said, bring the car to a reputable car shop to have the engine analyze with an engine analyzer. This kind of job is costly. If one of the sensors is bad, just replace the sensor to fix the problem of black smoke.

Clicking Noise on Front End When Turning

If the car is driven in a curve road and there is clicking noise on the front end when turning, the reason why there is a clicking noise is either faulty outboard CV joints or a damage binding front end components.

 

Clicking Noise on Front End When Turning

1. Faulty Out Board CV Joints


The faulty outboard CV joints is a problem that happens when your car is a front-wheel drive. The front-wheel car has CV Joints. CV joints stand for constant velocity joints, this is a flexible joint that allows the engine to transfer power into the front wheels smoothly. There are two types of CV joints, the outboard CV joint, and the inboard CV joints. The outboard CV joints are the one that is nearest to the wheel. Usually, when the outboard CV joints are damaged it will create a sound similar to clicking when the car is turning.

Check the outboard CV Joint booth from underneath the vehicle where the clicking sound is heard. The booth is a rubber that contains the CV Joints. Refer to the manual to understand more the location of the CV Joints booth. Inspect the booth if it is damaged or a thorn in any way, if the booth is damaged, probably the dirt coming from the road is causing the damage, this is why clicking sound occurs. Bring the car to a car shop and ask the mechanic to inspect the CV joints for any damage since the booth is damage and there is a clicking sound occurred during turning.

2. Damaged Binding Front End Components

If your car is a rear-wheel-drive the possible cause of the problem is a damaged binding front end component. Since CV Joints problem is only possible for a front-wheel-drive vehicle. When the car is turning the front end components is under more stress than when the car is running on a straight path. The added stress can cause the front components to bind which results in clicking noise when the car is turning. The most usual parts that which causes the clicking noise is the steering knuckle, tie rod, control arm bushing or a ball joint.

Front End Components

Bring the car to a reputable car shop and have a mechanic to inspect the car front end and repair if necessary. You must address this problem immediately because the car is not safe to drive and it may result to a more serious problem if ignored.

My Car AC is Blowing Hot Air

 Car AC is Blowing Hot Air

The car Ac is blowing hot air suddenly or is blowing hot air slowly over a period of time. When turning the AC switch ON usually, cold air is coming out the AC vents. But when the AC switch is turned ON instead of cold air, hot air is coming out the vents.


Possible cause why car ac is blowing hot air

Major Refrigerant Leak

If initially when turning the ac switch the ac vents is blowing cold air, then suddenly the vents are blowing hot air, it is an indication of a major refrigerant leak. The refrigerant is a liquid inside the ac system. The liquid takes away heat from the passenger compartment and purges it to outside thereby creating a cooler environment from inside the passenger compartment. When there is a major refrigerant leak somewhere in the system because of ruptured hoses, the refrigerant will evaporate and the ac system will reduce its performance. Since the refrigerant evaporates, the ac vents will be blowing hot air instead of cold air.

Open the hood of your car and check the ac line for any ruptured hoses. Replace the ruptured hose.



AC Electrical Problem
The electrical system possibly the switches or wire is shorted or the fuse of the ac unit break which causes the ac system to malfunction. Check the fuses if busted. If the fuses are busted then this is what causes the problem.

Even though the fuse is replaced, it is most likely to be busted again because the cause why the fuse is busted is not yet identified and repair. Therefore bring the car to a reputable shop and have the ac electrical system examine by a qualified mechanic.

Small Leak on the AC system
If the ac blows cold air then slowly blowing hot air over a period of time, it only means that there is a small leak somewhere on the ac system. A small leak on the system tends to drain out the refrigerant slowly over a period of time and slowly reduces the ac performance.

Car AC Not Cold Anymore

If the car AC is not blowing cold air anymore over time it is an indication of a slow refrigerant leak or a clogged condenser.
Read more: Car AC Not Cold Anymore

Bring the car to a reputable shop that specializes in car air conditioning system. Ask the mechanic to check for any leak on the system and have it repaired.

Clogged Condenser
The condenser is one of the components of the car ac system that serves as a mini radiator that removes the heat that the refrigerant absorbed on the passenger compartment. Over time the condenser will be clogged because of dirt or debris coming from the outside surroundings and it can slowly make the car AC to reduce performance which is why the car ac is blowing hot air.

 Car AC is Blowing Hot Air

Check the condenser for the buildup of dirt and clean using a soft brush and water. It should improve the performance of the ac system. If not then bring the car to a car shop that specializes in car air conditioning system. Ask the mechanic to examine the ac hoses for any leak on the system, also for the electrical system for any short circuit. Recharge the system with new refrigerant after the repair is done.

Car Stalls at Idle

Generally speaking, car stalls at idle is an indication of a fuel problem specifically lack of fuel. Reasons which cause the car to stalls at idle are a bad idle air bypass valve, a bad cold start valve, or a bad fuel pressure regulator.

Reasons why car stalls at idle

1. Bad idle air bypass valve
2. Bad cold start valve
3. Bad fuel pressure regulator

What to do?
Quickly step on the gas pedal and observe if the engine will continue running. If the engine continues to run it means that the problem is a bad idle air bypass valve. Fuel injection car has a device called idle air bypass valve, the purpose of this device is to maintain the idle speed of the engine. If this device is not functioning properly then the engine will stall. When the gas pedal is depressed when the engine is about to stall is an indication of a bad idle air bypass valve. By stepping the gas pedal will increase the throttle which compensates for the bad idle air bypass valve giving the engine enough fuel to continue running.  Replace the bad idle air bypass valve to correct the problem.

However, if the engine will not continue running even when the gas pedal is depressed then it’s not a case of a bad idle air bypass valve.

Now, observe if the car stalls while driving happens only if the engine is cold but will not happen after the engine has warmed up then the problem is a bad cold start valve. Fuel injection car has a device called a cold start valve. The purpose of this device is to keep the engine running when the engine is cold by providing the engine more gas so that the engines have a rich air/fuel mixture. Replacing the bad cold start valve will fix the problem.

If the air bypass valve and the start valve is not the problem then the only remaining possible reason why your car stalls while idling is a bad fuel pressure regulator. Generally speaking, car stalls at idle is an indication of a fuel problem specifically lack of fuel. Fuel injection car has a fuel pressure regulator, the purpose of this device is to maintain the fuel pressure to each of every injector. If there is a problem with this device the engine will be deprived of fuel which will cause the car to stall. Replace the fuel pressure regulator to fix the problem.


Bring the car to a shop and ask the mechanic to verify the problem, if the problem is confirmed replace the defective parts as necessary.

Clutch Pedal Vibration - What's the Risk?

The clutch pedal vibration is a problem that should concern you when it happens while depressing the clutch pedal. It's not a simple problem as you think it is, it's a risk to continue driving your car with a vibrating clutch pedal. 



It will not only creates a problem on the car but also damage important components of the transmission, it starts as a small problem and become bigger as you continue driving the car with a clutch pedal vibration, this will result in a more expensive repair. Continue driving the car will also increase the risk of stalling. There are three possible reasons why would a vibration in the clutch pedal occurs.

Possible Reasons for a Clutch Pedal Vibration

(1) Loose clutch disc
(2) Loose pressure plate
(3) Loose flywheel

Image Credit

To determine the reasons that cause the problem, the transmission assembly must be opened up. It is very difficult to determine the real cause of the problem without looking inside the transmission. usually,  cause if there is a clutch pedal vibration when the clutch pedal is depressed a loose clutch disc, pressure plate, or flywheel is the problem. These three components are somewhat connected to each other.

The clutch disc is fitted in between the pressure plate and the flywheel, the purpose of the clutch is to transmit or cuts off the power produced from the engine to the transmission.

The flywheel is a round plate that is coupled to the engine crankshaft, the crankshaft is the one that makes the flywheel runs. When the car is in gear the pressure plate presses the clutch disc against the flywheel this allows the engine power to be transmitted to the transmission. Back to the problem, if the clutch pedal is depressed the clutch pedal is released in this case if there is looseness on any of the above-mentioned parts the parts will wobble and that wobbling will be transmitted on the clutch pedal thus creates clutch pedal vibration.

How to correct clutch pedal vibration when the pedal is depressed

No other choice but to bring the car to a shop specializing transmission repair, probably the transmission will be opened up to determine the exact cause of the problem. This kind of work is expensive so make sure that the shop where you bring the car is a reputable one to avoid a low quality of work.

Car Shakes When Braking

When the entire car shakes when braking the only possible reason is the rear drum and the rear brake shoe is maligned, when those two components are not aligned with each other the shaking affects the entire car.

Rear Shoes and Drums is Misaligned
Usually, when the entire car vibrates when the brake is applied, this means that there is something wrong with the rear brake.

Car Shakes When Braking
Image Credit

What is happening here is that the rear shoes and the drums are not aligned to each other and is not even contact during brake application. If those two parts are misaligned it can cause vibration. Now, why is it that the shoes and drums are not aligned?

Usually, the most common cause of misalignment is a warped rear drum. It is also possible that the rear drums are good, if this is the case then the problem is the rear wheel bearings. The bearings are already worn out or loose. A bearing that is worn or loose can cause an indirect misalignment between the shoes and the drums.

Bring the car to a reputable car shop and ask the mechanic to first check the rear bearings for any looseness or wear. If the rear bearings are in good condition, the next thing to do is to have the rear brake drums machined so that the warpage of the drum will be corrected.

Once the drum is corrected, you need to replace the brake shoe because it will not be aligned well to the corrected drums it is necessary for the machined drums to be fitted with new shoes so that both parts will have even contact with each other during brake application to avoid car shakes when braking.

Battery Light On and Off While Driving

The battery warning light indicator on dashboard is occasionally on and off while driving the possible reason is that the alternator is failing or the alternator belt is slipping.


Possible cause of battery light that flickers
1)The alternator belt is slipping.
2)The alternator itself is failing.

When the battery dashboard warning lights indicator flickers while the car is running there are two possibilities that causing this kind car trouble, as mentioned above it can cause by the slipping alternator belt or a failing alternator. The alternator is the device that provides electricity to the car battery, it is connected from the engine using an alternator belt, when the engine runs some of the power will be transferred to the alternator to make it runs and create electricity so that the battery will charge, aside from providing charges to the battery the alternator is also the one that provides electrical power to all your car accessories like the radio, air con, lights, etc. while the engine is running. Now, if the battery warning light indicator located on the instrument panel is lit “ON” then it means that the alternator is not generating electricity that the car accessories are needed.

Since the problem is the battery warning lights only flickers, sometimes on and sometimes off, then the problem is intermittently occurring which means that the alternator is sometimes generating electricity and sometimes not generating electricity or somewhat failing, during the time the alternator fails it cannot generates electricity and the battery warning lights is always on.

Brake Warning Light Came On Steadily While Driving

Lack of brake fluid or low brake fluid is also the common reason why the brake dashboard warning lights came on steadily while driving. When you are driving find a safe place to stop then open the hood of your car.

Read more : Brake Warning Light Came On Steadily While Driving

Also when the alternator belt is slipping the alternator cannot generates electricity, as mentioned above, the alternator is connected to the engine using the alternator belt, now if there is a problem on the alternator belt, for example, if the belt is broken the alternator will stop running and you can see the battery warning lights steadily ON, however since the warning lights only flicker this means that the belt sometimes fine and sometimes not which is usually a symptom of slipping belt, every time the alternator belt slip the alternator stop generating electricity this triggers the battery warning lights indicator on the dashboard to came “ON”.

How to fix for the flickering battery warning lights

Bring your car to a shop and ask the mechanic to check the alternator. More often than usual the belt is only needed some adjustment to fix it. But if the belt is no problem then it is the alternator that causes the problem, probably it is failing and it is necessary to replace the alternator. Have it fix soon because you may not be able to drive the car when the alternator failed completely.

What Causes Ticking Noise in Engine While Running

Ticking Noise in Engine

 

What causes ticking noise in the engine? If ticking noise in the engine is heard while running is an indication of a poorly lubricated engine. The reason for this is the oil inside the engine is not enough or just simply the engine lacks engine oil or the oil pressure inside the engine is low.


Ticking Noise in Engine

What causes ticking noise in the engine?



Ticking noise is related to engine oil problem, with that said the focus of troubleshooting for this kind of problem is limited to checking the engine oil do the following.

1) Lift the hood of the car and locate the dipstick for the engine oil. Check the engine oil level by removing the dipstick. Wipe the end portion that dips with oil using a clean cloth.

2) Put back the dipstick on the original location (dipping it again on the engine), and put it out again and check the reading. If the reading is below the full line then the engine oil is low.

Ticking Noise in Engine

How to Check Engine Oil video credit

When the engine oil is low then the engine is poorly lubricated. This causes the engine ticking sound that you heard coming from the engine.

How to Check Oil in the Car
If the low oil warning lights on the dashboard is on, you should check the engine oil level immediately and add engine oil as needed. Before you drive your car in the morning checking the oil in the car must be done when the engine is cold.

Read more : How to Check Oil in the Car

If the dipstick reading is within the full line this means that the oil level is enough and brings us to the next possible reason for engine ticking which is a low engine oil pressure inside the engine.

Now to confirm if the oil pressure inside the engine is low, Observe the oil indicator on the dashboard, if the oil indicator light comes on while the ticking sound occurs when there is a problem with lubrication system, why does your car's oil light come on? well, it is a case of low oil pressure. Otherwise, it is a leaking exhaust manifold or a loose valve is causing the ticking sound in the engine.

Ticking Noise in Engine

When the oil pressure is low not enough oil will reach most of the engine components causing ticking noise from the engine. What causes the oil pressure to become low? The oil pressure will become low if the oil pump is faulty or if the oil pan screen is clogged.

Possible cause of ticking noise in the engine
Poor engine lubrication because of low engine oil level, low oil pressure because of faulty oil pump or clogged oil pan screen, loose valve or leaking exhaust manifold.


How to fix ticking noise in the engine
Engine lubrication is poor. Add enough oil in the engine. Consult the vehicle owner’s manual for the type of oil to be added.

Ticking Noise in Engine

Car Jerks When Accelerating

Car jerks when accelerating especially during cold rainy morning when the engine is cold. Several reasons are causing it depending on the condition of the car when it happened. 

Possible reasons why car jerks when accelerating
Moisture in Distribution Cap

Since the acceleration problem happens when the engine is cold especially during wet morning this suggests moisture in the distributor cap. This happens because when you park the car overnight especially on the outside, moisture is formed inside the distributor cap because of the wet weather. The moisture allows the electrical current to arc inside the distributor cap that causes engine misfiring because of uneven power is produced and when the engine misfire the car jerks when accelerating.

How to avoid the car to jerks when accelerating because of moisture in the distributor cap. To avoid having moisture in the distributor cap from happening park your car inside the garage if you expect rain to come.

Vacuum Leak

If the car jerks gradually happened when accelerating and become worse over time. When the car jerking happens gradually and becomes worst overtime then this indicates a possible problem of a vacuum leak. When the car has a problem with a vacuum leak it will not be noticeable initially and it will become noticeable when it gets worst. The fuel system creates a vacuum in which is one of the key factors in determining the amount of fuel the engine will get. When there is a vacuum leak on the system the amount of fuel the engine gets will become wrong and this will result in car jerking.

Bring the car to the car shop and ask the mechanic to check for any vacuum leak on the system. Usually, the most common parts that are always the source of a vacuum leak is the Exhaust Gas Re-circulation (EGR) and the PCV valves which you should suggest to the mechanic to check.


Faulty Throttle Position Sensor 

If the car jerks happened constantly when accelerating at any engine temperature When your car has a fuel injection system usually the reason for this problem is a bad throttle position sensor. The throttle position sensor is a device present in a fuel injection system, the purpose of this device is to measure how far the driver depressed the gas pedal and feed the data to the car computer which calculates how much fuel the system should inject into the engine. Now, when the throttle position sensor is bad wrong data will be sent to the computer and the amount of fuel injected to the engine will also become wrong that is why the car jerks during acceleration.

Throttle Position Sensor

Bring the car to a shop and ask the mechanic to check the throttle position sensor. Explain to the mechanic the symptom of the problems you have noticed for a better understanding of the problem and made the troubleshooting easy.

What Would Cause an Engine to Lose Power?

What would cause an engine to lose power? If an engine loses power especially those of low mileage car is caused by a fault in the ignition system or fuel system. Observing the engine behavior will point out to the exact problem, like for example if the engine is rough on idle it means that the spark plug or the spark plug wires are bad.


Engine to Lose Power

A bad spark plug or wires can cause an engine to misfire, in this condition the engine will not operate properly and will lose power. In this case, just replace the affected spark plug or the spark plug wires to fix the problem.

Another reason why an engine loses power is when there is a problem with the fuel system. Usually, a clogged injector is more likely the cause of the problem. Fuel injection system provides the engine with enough amount of fuel, now if the engine does not provide enough amount of fuel it will lose power.


If the injectors are clogged or partially clogged it will not squirt enough fuel on the engine and will result in fuel starvation when the engine starved of fuel will lack power. Bring the car to the repair shop and ask the mechanic to check the fuel injectors, the injectors will have to be clean or replace if necessary.

What Causes Vibration in the Steering Wheel?

What causes vibration in the steering wheel? the steering wheel vibrates especially when the car reaches a certain speed. The vibration is enough to be felt by the driver. There are two reasons that causing the vibration the first one is if the front end parts are loose and the other one is if the front wheel is an imbalance.


Vibration in the Steering Wheel

Possible cause of car steering vibration
1)The front end parts are loose.
2)The front wheel is an imbalance.

Car problem diagnostic
When steering wheel vibrates at a certain speed there are two possible reasons that causing this kind of car trouble its either some front end parts are loose or there is an imbalance between the front wheels.

The front ends parts that are more likely to lose which may result in steering vibration when the car reaches a certain speed are the tie rods and the ball joints. The problem occurs when the car reaches a certain speed the vibration will become extreme since the vibration is extreme it can easily be felt on the steering wheel because the steering wheel is connected to the front end of the car.


Also when the front wheels are imbalanced it can cause the steering wheel to vibrates because the wheels are produced with heavy spots, when wheels are produced in this condition it means that the weights are unevenly distributed all throughout the wheel. If the weight of the wheel is not evenly distributed the wheel will rotate unevenly as the tire is rolling, the uneven rotation will create vibration especially when the car reaches a certain speed. The created vibration will then be transferred to the steering linkage all the way to the steering wheel since the steering wheel is connected to the front end which the tire is also connected. The weight of the wheel becomes uneven if the wheel balance is detached from the wheels this happens when the wheel balance is not perfectly fit the wheel. Wheel balance is a piece of metal that is attached to the wheel to correct imbalance making the wheel to become balance.

What to do?

How to correct the vibration of the steering wheel at a certain speed


When the steering vibrates after the car reaches a certain speed, before looking at the front end components, first thing to do is to subject the front wheels for balancing, more often balancing the wheel can usually fix the problem of steering vibration, however if after balancing the steering wheel still vibrates then that is the time to look into the front end, your option is to bring the car to a shop and have the front end check by a mechanic.

Why Does My Car Just Dies While Driving?

Why does my car just die while driving? Car runs then dies after several seconds. Lots of things can cause this kind of problem, the causes depend on the condition when the problem occurs. The engine will run on a few seconds then dies, this situation is called “Run On”. Run on makes the Engine dies when the engine is extremely hot.


The cause of the problem is extreme internal engine heat. When the engine temperature is too high any unburned fuel that is inside the combustion chamber will self-ignite and runs on occurs until all the unburned fuel is burned up.

What to do?
When this problem occurs there is nothing much you can do. However, using high octane gasoline can prevent this problem from happening because high octane gasoline tends to burn slowly and resist run on than the low octane gasoline. Also, bring the car to a shop and ask the mechanic to check the engine cooling system since the engine develops extremely high temperature that causes run on.

When engine idling speed is faster than normal

The most likely cause of the problem is fast idle speed Run On is also occurred when the idle speed is fast and when the idle speed is fast it means that the engine received fuel at a faster rate than normal. This cause unburned fuel remains inside the cylinder and will self-ignite when the engine is extremely hot and runs on until all the fuel is burned up. To fix the problem lower the idle speed, when your car is fuel injection the idle speed must be adjusted by a qualified person because it is a difficult job for a person with no knowledge on the system because usually it cannot be adjusted but rather you have to replace some parts in correcting the idle speed.

For a car with fuel injection system

This problem can cause by a leak on fuel injectors. Usually, this problem occurs on the fuel injection system when the fuel injectors are leaking.

Image Credit

Supposed to be when the engine is shut off the fuel injectors is closed and prevents the fuel to leak out into the cylinder. If there is a leak, the fuel will self-ignite when the engine temperature is high thus run on occurs. Bring the car to shop and ask the mechanic to check the injectors for any leak. Replace the injectors to correct the problem.

Why is My Manual Transmission Grinding?

Why is my manual transmission grinding when shifting? Transmission is very complex parts that are why when there is trouble it is very hard to diagnose without looking at the actual transmission, the diagnosis mention in this article is just a possibility unless the actual transmission is inspected.


If there is grinding on the transmission when shifting to one particular forward gear the possible reason is that there is a problem with the synchronizer of that particular gear. What is inside the transmission is a device called the synchronizer, the purpose of the synchronizer is to bring the rotating shafts/gears together at the same speed for smooth shifting. If the synchronizer is faulty a grinding sound occurs and shifting will become impossible for that particular gear.

But if the grinding occurs only at first gear just after shifting from a stop and not during downshifting the possible reason is that there is too much clutch pedal “free play”. Free play is the distance of the clutch pedal movement before the clutch begins to disengage. If there is too much pedal free play even when the clutch pedal is press all the way down, the clutch is still not fully disengaged and will results in grinding sound when shifting into first gear.

Seek the help of the mechanic specialized in transmission repair to inspect the transmission, if the mechanic recommends tearing down the transmission do not agree without seeking a second opinion. The problem may be solved by simply adjusting the clutch pedal free play, mention this to the mechanic.

Radiator Boils Over when the Engine is Semi-hot

The radiator boils over even though the engine is semi-hot. The two possible reasons are causing this problem, first is a leaking radiator cap, second is a wrong anti-freeze/water ratio.



Possible Cause why the Radiator boils over even when the Engine is semi-hot
Leaking Radiator Cap

If the radiator boils over even when the engine is semi-hot, it is most likely caused by a leaking radiator cap. The radiator cap is the one that keeps the entire engine cooling system under pressure which also resulted in the rising of the boiling point of the coolant inside the radiator. Now, if the radiator cap is leaking the boiling point of the coolant will be less than that of the normal. If this happens the engine and the coolant will only need to be semi-hot for the radiator to boils over.

How to Pressure Test Radiator Cap

Remove the radiator cap, but before removing make sure that the engine cools down. Examine the radiator cap for any cracks on the rubber part then put back the radiator cap and check if the cap is securely attached to the radiator fill hole. If there is something unusual on the radiator cap like looseness then replace the cap with a new one. Usually, this will fix the boils over the radiator even when the engine is semi-hot.

Wrong Anti-freeze/Water Ratio
Anti-freeze is the one that keeps the water from freezing with added into the water when the temperature of the outside surrounding is very low. The anti-freeze also raises the boiling point of the water usually the water coolant ratio is 50/50 mix. With this mixing, it is adequate for both freeze and boils over protection.

Now if the mixing is not correct like there is more water than anti-freeze then the coolant will boil at a much lower temperature in this case even when the engine is semi-hot.

Coolant Boiling Over After Engine Start

If the radiator boil over after engine start, it indicates a leaking radiator cap or a wrong anti-freeze / water ratio.

Have the entire cooling system back flushed to completely remove the old coolant inside the cooling system then replace the coolant with a 50/50 mix of anti-freeze and water.
