Squealing Noise When Letting Clutch Out


If there is squealing or howling when letting clutch out, the problem often indicates the following.

(1)Faulty throughout bearing or faulty pilot bearing

Let's examine each of these possibilities. While releasing the clutch pedal, the clutch linkage pulls something called a throughout bearing away from the pressure plate. The pressure plate is then able to press against the clutch disc causing the clutch to become engaged. Now, as the throughout bearing is being pulled away from the pressure plate, it is rotating. If it's faulty, it will often make some sort of noise (commonly that of a squealing/howling sound - as you indicated in the problem you chose).

In the second case, again, while releasing the clutch pedal, the clutch is engaging. This means something called the pilot bearing (connects the crankshaft to the transmission input shaft) will have stress on it. If it's faulty, it will similarly make a squealing/howling noise. By the way, if the noise is louder when driving up a hill as opposed to a flat road, it's more likely the pilot bearing is at fault.

What to do?

Unfortunately, there is no easy way around this problem other than having the clutch/transmission assembly opened up and examined by a mechanic. Hopefully, this vehicle is covered under either some sort of warranty or a service contract. If not, try to find a car repair shop which is very reputable.

White Smoke from Exhaust - Diesel Engine

White Smoke from Exhaust Diesel Engine

If you notice the white smoke from exhaust of diesel engine only when the engine is very cold, then it is normal. This is because the condensation is steaming off.

When a cold engine is started, any condensation that has formed, say during the night or while the engine sat, will steam off and come out the exhaust. This is perfectly normal and nothing to worry about.

What to do?

Do nothing. No Remedy Necessary.
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.

As indicated that the white smoke coming from the exhaust appears at all times. This is a clear indication of a blown head gasket. The head gasket is a thing which goes between the cylinder head and the engine block.


Basically, it does what any gasket is supposed to do - seal something or keep something from leaking. A head gasket keeps the water from entering the cylinders. When it is "blown" or has a break in it, what then happens is some of the water (that is used to cool the engine) leaks into a cylinder and burns off as steam. This steam then comes out the exhaust.

What to do?

You'll need a new head gasket. If you would like to do this procedure yourself, refer to the appropriate auto manual for detailed instructions. Beware that this is a fairly involved job. Otherwise, find a reputable shop to do the work. Explain to the mechanic exactly what this article explained to you.

Brake Warning Light Flashing

Brake Warning Light Flashing
If the brake warning light is flashing, this generally indicates that the brake fluid is slightly low.

You might not know but at the top of the brake fluid reservoir, there's a sensor that causes the brake warning light to go on whenever the brake fluid level is low. Since the brake warning light is flashing while driving for a second or so and did not stay on continuously, the brake fluid level must be just slightly low.


You probably noticed the light flashing when you drove over a dip or bump. This caused the brake fluid in the reservoir to slosh and, for a second, the fluid was not in contact with the sensor. Consequently, the warning light came on.

What to do?
Buy yourself a can of high-quality brake fluid ("DOT 3" or "DOT 4", as it's called) and carefully add just enough to top off the brake fluid reservoir. Do not leave the brake fluid reservoir open any longer than necessary. Doing so will cause the brake fluid to become contaminated by moisture in the air and this will then lead to a whole slew of new problems. Also, for the same reason, throw the can of brake fluid away when done.

From a Stop Car Shake as Clutch Pedal is released



Without a professional inspection of the transmission, it's hard to determine the exact cause of this problem. But the most likely cause of the problem is the following.

(1)Loose engine transmission bolts, or faulty clutch disc.

As mentioned, only a professional mechanic can determine the exact cause of this problem. However, the suggested causes are good guesses. Why? Well, in the first case, the engine/transmission bolts are of course necessary to keep the engine and transmission connected and stable.

If one or more of the bolts is loose, the transmission assembly will have a tendency to vibrate. This vibration will be most noticeable when the clutch engages from a stop (i.e. when the clutch pedal is released) and, as you indicated in the problem you chose, even cause the entire vehicle to shake.

In the second case, when the clutch pedal is released, the clutch disc is pressed against something called the flywheel. This allows the transfer of engine power to the transmission. If the clutch disc is faulty (e.g. warped, bent, loose), it will not make even contact with the flywheel. As a result, severe vibration will occur between the two parts which can be felt throughout the vehicle.

What to do?
In this situation, you'll really have no choice but to take this car to a repair shop and have the mechanic examine the clutch/transmission assembly. Hopefully, for your sake, this car is covered under some sort of warranty or a service contract. If not, try to find a reputable car repair shop specialized in transmission repair and bring the car for repair.
