Why does my car squeal when it is cold?

Cold weather can exacerbate underlying car problems, so you may begin to hear squeaks, squeals and other funny noises you haven't heard before. These noises may be caused by the engine belt, the serpentine belt, the air conditioning compressor or a power steering pump.

Why does my serpentine belt squeal when it's cold?

The cold weather causes rubber to be less pliable and a bit brittle. As the engine pulleys turn the rubber belt at a very rapid pace, this will cause them to squeak a bit until the rubber material warms up and becomes more pliable. This may also happen when the belt needs to be tightened up.

Why is my car making a high pitched squeal?

1. 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 my car squeal when I turn on the AC?

A loud squeal is produced when the A/C is turned on. This symptom is usually caused by a loose or worn air conditioning compressor belt. ...

Hissing or Screeching

If your air conditioning unit is emitting a high-pitched screeching or hissing sound, the most likely cause is high pressure built up in your compressor. If this is the case, the sound will most likely be heard outside at the unit when the AC first kicks on and will last about 10-15 seconds.

What makes a serpentine belt squeal?

Worn/Cracked Serpentine Belt – Serpentine belts have grooves which fit into grooves in the pulleys. Over time, the friction wears down these grooves, resulting in a loose fit. A worn belt can, therefore, begin to slip, which is one of the causes the squeal. Alternatively, cracks can cause the belt to snap.

How do I know if my AC compressor bearing is bad?

A worn bearing will produce a high pitched squealing or grinding sound, while a seized bearing will produce a grinding noise or a noticeable belt squeal.
