How do you find a serpentine belt routing diagram? ›

Some vehicles have the serpentine belt diagram located on a decal somewhere in the engine compartment. But if your car does not have a decal, you can easily look up the diagram in a repair manual or repair database. Another option is to take a photo of the old belt before removal.

What Does a Serpentine Belt Do? As we mentioned early, a serpentine belt delivers power to your alternator, power steering pump, and air conditioning compressor.

Straightedge or String Line: Place a straightedge or taut string along the faces of the pulleys to see if they line up perfectly. Any deviation from a straight line suggests angular or parallel misalignment.

A car's serpentine belt helps power many of the vehicle's accessories, including the water pump, the alternator, and the power steering pump, to name a few. Older cars may have a serpentine belt that requires manual tightening to keep things running smoothly, but most modern cars have automatic belt tensioners.
