Why is my belt squealing when I accelerate?

Why is my belt squealing when I accelerate?

This is a common sign of a loose or worn belt. When this happens as you press the gas pedal and the belt goes from a relatively low speed (at idle or when first starting the car, no speed at all) to a much higher speed as the engine accelerates, this can cause the belts to squeak.

What does a slipping fan belt sound like?

A loose drive belt will often be noisy, squeaking a bit, or emitting a high-pitched squeal. The most obvious sign of a loose drive belt, though, is in its appearance and tension. A loose belt, simply stated, looks and feels loose. These belt driven components can affect the tension of a belt.

Is it bad to drive with a squeaky belt?

That’s why it’s recommended that the serpentine belt is replaced early when the squealing symptoms are first noticed. Although it may be safe to drive with the squealing for a few days or weeks, the belt will eventually need to be replaced, and for safety, the earlier it’s repaired, the better.

What to spray on belt to stop squeaking?

Spray just enough WD-40 onto the belt to lightly cover the area where the squeal occurs. Short, sharp blasts work best to ensure the belt is not saturated. Oversaturating the belt will result in severe slipping, which can permanently damage the belt.

Why does my serpentine belt make a squealing noise?

How can you tell if a car belt is a chirp or a squeal?

One method to determine if the noise is a chirp or squeal is to use a water squirt bottle and spray the rib side of the belt while the vehicle is running. If the noise gets louder, it’s a squeal. If the noise goes away, it’s a chirp.

Where are the timing marks on an Acura water pump?

When the crankshaft timing marks are aligned, check both cam timing marks to ensure all marks are aligned (left and right sides, Figure 7). As Murphy’s Law will have it, the crankshaft will most likely be 360° out.
