Why Is My Car Squealing?

Why Is My Car Squealing

If your vehicle is making a high-pitched squealing noise, it’s trying to tell you something. Be sure you listen to what it has to say.

Whats That Sound?

A squealing sound is quite common and can result from a number of different causes including:

The Belt System

Constant squealing when you accelerate, or when you first turn the car on, may be related to your belt. Today’s newer vehicles have a single belt, known as a serpentine belt, which replaces multiple v-belts. Serpentine belts are usually good for 50,000-100,000 miles, although damage can occur before. To see if your belt is damaged, check for cracks, wear, fraying or pieces of missing rubber. Replace damaged belts as soon as possible.

Tensioner

The tensioner controls the belt’s tightness on the pulley system. When the belt is loose, it can shimmy back and forth on the alternator, water pump, air conditioning unit or drive pulley.

Worn Alternator Bearings

If the bearings of your alternator are worn out, it will also create screeching and should be dealt with right away.

Slippage

If your belt is wet or cold, which may occur if your car is parked outside over night, it may slip for a few seconds until the rubber has warmed up.

Squealing While Braking

A loud, metal-like, screeching sound likely means you need to have your brake pads changed.

 

If your vehicle starts making squealing noises, it is important to determine the cause and resolve the issue to ensure your vehicle’s longevity.
