How to Disconnect a Car Battery

Do you know how to disconnect a car battery? Which battery cable should be removed first? let's say you need to clean or replace the battery of your car so you disconnect the battery. Here's what you do to disconnect the car battery.


How to disconnect a car battery

1. First is to park the car in a safe place then turn OFF the engine, make sure that the car is a park on level ground and the parking brake is engaged, and use a tire stopper for safety purposes of shift the gear into reverse gear if there is no parking brake or tire stopper.

It is very important to turn off the engine before disconnecting the battery because the battery contains electrical charge and flammable gas produced by corrosive agents, this is done to avoid the possibility of the fire accident.

2. Now, Locate the battery negative terminal. Usually it contains a black plastic indicator label or a negative symbol embedded on the battery casing, however, if you cannot find both locate the word “NEG” on the battery case near the terminal. The terminal with a red plastic label is the positive or with a positive sign embedded on the battery casing located near the terminal, sometimes a word “POS” is printed on the casing near the battery pole.

3. Once the negative terminal is located, check the type of tools to be used for loosening the terminal nut. Usually, an open wrench or socket with a size 10 mm is used to loosen the terminal nut.
Disconnect the negative terminal first, this is to prevent short circuit when the tools you use touches the body of the vehicle.

If you disconnect the positive terminal first, there is a possibility that the tool touches the vehicle body and short-circuited the system.

4. Disconnect the terminal. Start disconnecting the cable on the negative terminal. Remember that it is not necessary to remove the nut on the terminal you just need to loosen the nut of the battery cable to disconnect the terminal.

5. After the negative terminal was disconnected, proceed with the disconnection of the positive terminal.

6. Now loosen the battery clamp to completely remove the car battery.
A disconnecting car battery can become dangerous if not done correctly that is why it is important to know how to disconnect a car battery so that you may avoid an accident when you want to replace your car battery.

To replace the battery, be sure that the battery is mounted correctly, with the side of the terminal facing the right side of the vehicle. Be sure that the battery tray and the pressing board are correctly fixed so as to prevent the battery from moving in the event of an accident or emergency braking.

How to Check Tire Air Pressure

How to Check Tire Air Pressure

The tire tread life will be reduced if the tire air pressure of your car is below the car manufacturer tire air pressure specified on your car owner’s manual. Aside from reducing tire life, it is also believed that having a lower tire pressure could also reduce fuel economy and to prevent those from happening. When checking for the tire air pressure, do it after running for about 1km.

How to Tell the Age of a Tire

Do you know how old is your tire? How long do car tires last? Is there any way to determine the expiration of the tire? how to tell the age of tire?

The correct tire pressure can prolong the service life of tires. It can also ensure the best combination of driving comfort, fuel economy and drivability. When the tire pressure is too low, it will intensify tire wear, greatly affect the drivability and fuel economy of the vehicle and increase the danger of lost tire effectiveness. If the tire pressure is too high, it will cause driving instability and uneven tire wear, thus reducing the service life of the tires.

Check tire pressure (including spare tires) at a frequency of at least once a week. Tires must be checked when they are in a state of normal temperature - as long as the vehicle has been driven for 1.6 km, it is enough to make tires fully heat up, thus affecting tire pressure. The pressure of hot tires is bound to increase. If tire pressure has to be checked when the tires are hot (after the vehicle has been driven for a period of time), the pressure should have risen approximately by 0.2~0.5bar. In such a situation, please do NOT deflate the tires for the purpose of making the tire pressure up to the standard.

The recommended tire pressure is located on the driver side, when you open the driver side door there is a label adhered on the panel, in the absence of a label, you can also find the recommended tire pressure for your car on your car owners manual.

When to Check Tire Pressure?
Tires should be checked at least once a week. Do NOT forget to check compact spare tires. Their pressure should be 4.2bar.

How to Check Tire Air Pressure

How to Check Tire Air Pressure

A high-quality mini tire pressure gauge may be used to check tire pressure. It is not possible to determine whether the tire air pressure is normal by just visually checking the tire. Even if not adequately inflated, radial tires still look very normal. check inflated tire air pressure when tires are cold. “Cold Tires” means tires that have not been driven for more than three hours or have been driven not over 1.6 km.

Step1. Remove the tire valve cap. First is to remove the tiny cap that is installed on the tire valve.

Step2. Hold tire gauge over the valve. The tire cannot be judged correctly for over inflation or under inflation by simply looking at it without using a tire pressure gauge. Use a Tyre pressure gauge to accurately check the Tyre pressure. Place the other end of the tire pressure gauge on the air valve inlet, the same position in replaces of the valve cap.

Step3. Press the tire gauge. Now firmly push the tire gauge straight to the air valve inlet. Hold the tire gauge from this position until the gauge scale displays the reading. Press the tire pressure gauge to the valve with force, and then the tire pressure will be displayed. No adjustment will be needed if the inflated pressure of the cold tire meets the recommended pressure valve on the tire and loading information label. If the pressure is too low, it is needed to inflate until the pressure value reaches the recommended value.

Step4. Compare the reading against the standard tire air pressure set by the car manufacturer, correct tire air pressure should be found on the car owner’s manual. If necessary, add air on the tire to increase tire air pressure then check again with the tire gauge. If the tire air pressure is too high, the valve core may be pressed to deflate until the pressure value reaches the recommended value

Step5. After the check is completed, make sure to return the valve cap back on the valve core. The valve cap can prevent dust and moisture from entering the tire.

Tire Check and Rotation

Tires should be rotated for every 8,000 to 13,000 km driven. Whenever abnormal wear is found, you should rotate the tires as soon as possible and check the wheel alignment. It is also necessary to check to see whether the tires or wheels are damaged.

How to Change Flat Tire


What do you do when you have a flat tire? When you drive there is always a possibility that you will encounter a flat tire, that's why before driving one of the items that are necessary to check is the tire including the spare tire and the tools used for replacing a flat tire. If your car encounters flat tire here is what you do.


The first thing to do is to pull off the road away from the traffic as possible. 

How to Change a Flat Tire

Step4. Ready the spare tire and the car jack. Get your spare tire and put it near the flat tire before you jack up the car.

Step5. Jack up the car. Place the car jack underneath the car in a position enough to lift the flat tire. If you do not know where to place the jack, try looking at the car owner’s manual it shows the location where to put the jack underneath your car. Make sure that the ground where you put the jack is solid enough to support the jack and the vehicle weight when the jack lifts the car. Lift the car enough to install the spare tire.

Step6. Remove the wheel nut and the spare tire. After the car is lifted, it is now time to remove the wheel nut by the use of tire wrench or hand the wheel nut can easily be removed because you already loosen the nut before the car is lifted. Lay down the flat tire on the ground.

Step7. Install the spare tire. Before installing the spare tire wipe the stud bolt with a rag to remove some dirt that may affect the tread of the wheel nut. Install the spare tire and the wheel nut. Hand tight the wheel nut.

Step8. Lower the car and remove the jack. Now lower the car until the tire touches the ground and the jack can be remove.

Step9. Tighten the wheel nut with tire wrench. Finally using the tire wrench tightens the wheel nut. Tightening the nut must be done correctly so that the tire fits well with the axle and prevent vibration. Follow the below guide when tightening the wheel.

As you can see on the tightening pattern, the wheel nut is tightened in an alternate position, this will ensure that the back face of the wheel touches in an even surface with the axle.

How to Install a Car Battery

Installing a car battery is something that every car owner should know. It is not that difficult to install a car battery since it is something that every able person can do. So, how to install a car battery?


Step1. Boost charge the wet batteries to ensure top efficiency before installing.

Step2. Clean first the battery terminal posts thoroughly with a wire brush, remove any corrosion that already accumulates on the battery pole. Ensure that the terminal post is free from corrosion. If you can make the metal shine then it is better.

Step3. Turn off all lights and accessories that use electrical power. By doing so, it will minimize the possibility of sparks while installing the battery which may possibly cause short circuit.

Step4. Observe and inspect all the lights if there is one that fails to turn off because if there is one lights that always keep on, when the battery is replace with a new one it will possibly drain the new battery.

Step5. Carefully mark the polarity cable as positive or negative for identification because this will insure that the correct polarity is connected to the correct terminal post when installing a new battery.
