Why does my car belt make a noise when I start it?
Most belt chirps and belt squeals occur in the shortest spans between two driven components. So start the engine and spray a stream of water onto the ribbed side of the belt before it wraps around a pulley. If the noise goes away, but returns again in a few minutes, the problem is misalignment.
What makes a belt sound like a squeal?
If you have belt noise that sounds like a squeal or chirp, you’ve got an underlying problem that must be fixed. The #1 cause of serpentine belt noise is a worn automatic serpentine belt tensioner. Most people blame the belt and replace it only to find the belt noise returns.
What causes belt chirp in a new car?
Most new cars have an automatic belt tensioner. But they don’t last forever and as they wear they introduce tension issues that can cause squeal and misalignment problems that cause chirp. The #1 cause of misalignment is pivot bushing wear inside the automatic tensioner. The tensioner is made in two pieces.
Why does my car make noise when I turn a corner?
Alignment problems can also produce noise by causing tire scuffing. When the wheels are not aligned during a turn, a tire can shift sideways instead of rolling forward. Normal tire wear, when tire tread depth is very low, can lead to the same noise. Combined with excessive speed, this can cause tire squealing and possibly a loss of traction.
Can a bad tire belt cause a thumping sound?
Once an abnormal wear pattern develops it can’t be corrected. You can choose to live with the noise or replace the tires. Bad tire belts usually result in a thumping sound. A general roar is usually just worn tire noise. I have two Sumitomo tires and two Ziex tires. The tires were rotated. Did not help.
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.
Why does the belt on my Car Make Noise?
This may be occurring due to any number of factors, including the following: Misaligned tensioner or pulley: If everything isn’t aligned correctly within the belt system, it will cause a slip and begin to make noise.
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.
