OEM Serpentine Belts

How to Make Sure You're Buying the Correct Serpentine Belt

The serpentine belt is a critical part that drives the alternator, power steering pump, and air conditioning compressor. Whether you own a Ford F-150, a Chevrolet Equinox, or a Volkswagen Tiguan, ensuring you have the correct belt is key to preventing breakdowns and costly repairs. The following are some tips to find a compatible drive belt for your vehicle.

Verifying Drive Belt Compatibility With Your SUV or Truck

1. Check the OEM Part Number

Compare the OEM part number on the old belt or in your owner’s manual to make sure your new belt matches exactly.

2. Confirm the Belt Length and Rib Count

Measure the belt’s length and rib count carefully to ensure a proper fit around all pulleys in the accessory drive system.

3. Inspect Existing Pulleys and Tensioners

Examine pulleys and tensioners for wear or misalignment so the new belt doesn’t slip, squeak, or wear too fast.

4. Look for Signs of Oil Leaks

Oil contamination can shorten belt life, so repair leaks before installing the new belt to prevent premature degradation.

5. Choose an OEM or Trusted Brand

Prioritize belts made by the OEM or other trusted manufacturers to maintain the durability and performance of your engine.

6. Confirm Fitment by Test-Fitting

Before fully tightening, test-fit the belt by routing it around all pulleys to verify tension and alignment are perfect.
