Why does my belt squeak until it warms up?
Most likely cause for this is that you have some condensation built up overnight on either the belt or one of the pulley wheels, and until this has evaporated the belt will be able to slip a little, causing a squeak. Once the engine warms up, the condensation is gone.
Why do my belts squeal when it’s cold?
Cold winter weather is never a friend to your vehicle. If your wheel well suffers ice accumulation, then strange noises will follow. If you hear squeals, then it could be your engine belt or serpentine belt. But in most cases, it will be your serpentine belt that is making these noises.
Why is my car making a high pitched screeching noise?
A high-pitched squeal when accelerating. If you notice a loud squeal when accelerating, especially if your car is just warming up, it could be that you have a loose or worn fan belt. Usually if your fan belts are worn, it could mean your timing belt needs to be replaced as well.
Why does the belt on my car keeps squealing?
Your engine belts make a screech or squeal noise usually because the rubber belt is slipping on the metal pulley and just like your tires spinning on the road, this causes noise. The belt may be slipping due to improper tension or because it simply has gotten old and the surface has become glazed, cracked or brittle.
Can you 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 causes a high pitched squeal when you change a belt?
A new belt is recommended once the accessory drive has been realigned. “Squeal” is a high pitched noise, typically lasting several seconds in duration. This type of noise will typically increase in volume as the engine speed increases, and is caused by relative slip between the belt and pulleys.
What should I do if my car squeals when I start it?
Most newer cars use a single, serpentine belt; older models may have as many as three belts. Look closely at the belt to see if it is worn, torn or otherwise compromised. Replace damaged belts immediately.
Why does my alternator squeal when I start my car?
One of two possible causes for this. Either your serpentine belt is worn out or your tensioner pulley is not doing it’s job (tensioning the serpentine belt). The pulley can wear out over time allowing the belt to slip a little. At startup there is a heavy load placed on your alternator, which causes it to squeal on the belt.
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.
