Most vehicles on the road today have a single belt-drive system that runs all the important accessories, including the alternator, A/C compressor, power steering and water pump.

The belt is running these accessories from both sides and is working harder than ever. Should this single belt fail, the results can be catastrophic, leaving you and the car on the side of the road with a very large tow bill. Spotting and diagnosing belt noise and belt-wear problems is very important.

When replacing the serpentine belt, it’s so important to replace the tensioner and pulley in the drive system as well. Doing the complete job will bring the drive system back to its original condition and maximize the life of all related components.
