A squeaky belt is a common car problem, often indicating wear and tear or misalignment. Ignoring it can lead to more serious issues like belt breakage, overheating, or even engine damage.

Identifying the Culprit: Pinpointing the Source of the Squeak
Before you start fixing, you need to locate the source of the squeak. Is it the serpentine belt, the alternator belt, or perhaps the power steering belt? A visual inspection is the first step. Look for cracks, fraying, or glazing on the belt’s surface.
Checking Belt Tension: A Crucial Step
Belt tension is critical. A loose belt can slip and squeak, while an over-tightened belt can put stress on bearings and other components. Use a belt tensioner gauge to check the tension, or if you don’t have a gauge, try pressing on the belt midway between two pulleys. There should be about an inch of deflection.
DIY Fixes: Tackling the Squeaky Belt Yourself
If you’re mechanically inclined, you can often fix a squeaky belt yourself.
Tightening the Belt: A Simple Solution
If the belt is loose, tightening it might be all you need. Locate the belt tensioner, usually a spring-loaded pulley. Use the correct tool to relieve the tension and adjust the belt.
Replacing the Belt: When Tightening Isn’t Enough
If the belt is worn or damaged, replacement is necessary. You’ll need the correct size belt for your car. Consult your owner’s manual or an auto parts store.
Lubricating the Pulleys: A Quick Fix
Sometimes, dry pulleys can cause squeaking. Apply a belt dressing or lubricant specifically designed for automotive belts. Avoid using WD-40, as it can damage the belt. For more complicated pulley issues, see our guide on fix a squeaky pulley in car.
