Belts

Belts transmit power and motion under your car’s hood. The serpentine belt transfers power to crucial parts such as the alternator, water pump, and the AC system. The timing belt ensures the motion of the camshaft and the crankshaft are in sync. Belts are often proclaimed as ‘maintenance-free’. However, doing regular checks and adjustments can help extend their lifespan.

How to Maintain a Car Belt

Whether you drive a Buick or a Chevy, make sure to turn off your vehicle and cool it down before inspecting the belts. If you don’t have a regular schedule for checking the belts, you can do it during every oil change. Once you’ve located your belts, check if each one is aligned on their pulleys correctly. Next, check the belt tensioner, which is important for keeping the belt in place. Any sticking or roughness on the tensioner is a sign of wear. Lastly, inspect the belt surfaces. If you notice multiple cracks and glazing on the belt, consider replacing it.

Should You Lubricate a Serpentine Belt?

No. Any spray lube, dressing, or oil applied on the belt can damage it or worsen its condition. A squeaking belt is a sign of slippage. Spraying lubricant, such as WD 40 or other lubes can make the slippage worse.
