Why is my brand new belt squealing?

Why is my brand new belt squealing?

Belt or pulley misalignment is a common issue that causes changed serpentine belts to still squealing. Misalignment means that the grooves on your belt are not aligned with the ones on your pulley. It also tells that you shift the belt a bit in or out in one of the pulleys.

Why does my serpentine belt squeal after replacement?

Noise of that type is due to a failed or failing bearing in one of the pulleys or accessories (e.g., alternator, water pump, A/C compressor) that is driven by the serpentine belt, the belt is not properly tensioned, or the rotating pulleys driven by the belt are not all in the same plane.

Do serpentine belts squeal when new?

If the replacement belt isn’t installed properly, even a brand new belt and new belt pulley won’t stop the squealing noise. Fortunately, it’s quite easy to detect this issue. If you’ve just got a new serpentine belt installed and yet you hear the squealing noise, chances are your mechanic didn’t do a good enough job.

How long will a squealing belt last?

The good news is a serpentine belt can last up to 50,000 miles or five years, with proper maintenance, before it needs replacing. Heat and friction of normal use slowly wear down the belt before it breaks.

Why is my car making a high-pitched squealing noise?

1. You hear 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 replaced as well.

Do belt squeal when too loose or tight?

A belt that is either too loose or too tight will often slip against the pulleys, causing the squeal. While the motor is running, pour water over the squealing belt. It the noise stops, it tells you the belt needs tightening.

Can you over tighten a serpentine belt?

An over-tightened belt can burn out any bearing that the belt rotates on, including alternator, power steering pump, A/C compressor, idler pulleys, etc. An over-tightened timing belt can ruin any pulley bearing it is connected with.

Is it okay to drive with a squealing 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.

Will serpentine belt make noise?
