Does a new timing belt squeal?
Does a new timing belt squeal?
The timing belt has teeth, like a chain, so it cannot slip and squeal. But it does wear out and break without warning. Earlier, the technician may have tightened your accessory belt or your power steering belt, not your timing belt. A worn accessory belt can certainly can slip and squeal if it is worn out or loose.
What to do when your car belt starts squealing?
When you are driving and it starts to squeal turn off anything that uses electricity. i.e. heater blower rear defrost, headlights if its safe. If the squealing stops then you need to get your charging system checked.
Why is my alternator belt still squealing after replacing?
For instance, the alternator works optimally with the serpentine belt connecting it to the engine pulley, enabling the alternator to turn together with other belt-driven components in your car. Belt or pulley misalignment is a common issue that causes changed serpentine belt still squealing.
Why does my serpentine belt make a squealing noise?
To easily detect if idler pulley is why new serpentine belt squeals on startup, you have to get a stethoscope to diagnose where the squealing noise comes from. Failing alternator bearing, steering pump, AC compressor bearing, and water pump generates similar noise.
Why does my pulley belt squeal in warm weather?
It can also be checked for tension by pushing down on it. Loose belts are more likely to squeal in warm weather. However, if the belt appears to be tight and in good shape, then the issue may be the internal bearings of the pulley. The same visual and tension check can be performed on the serpentine belt.

What causes a squeal when a V-belt slips?
The alternator, power steering pump, water pump, and air-conditioning compressor may all be connected to this serpentine belt. Older cars may not have a serpentine belt, but they do have different V-belts that drive different systems. When any of these belts begin to slip, the resulting friction can cause a piercing squeal.
My car has 134000 miles. 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.
It can also be checked for tension by pushing down on it. Loose belts are more likely to squeal in warm weather. However, if the belt appears to be tight and in good shape, then the issue may be the internal bearings of the pulley. The same visual and tension check can be performed on the serpentine belt.
