The serpentine belt on a 1993 Chevrolet is a ribbed belt that drives several of the engine’s peripheral devices, such as the air-conditioning compressor, the alternator, and the separate pumps for power steering and coolant. Replacing the serpentine belt can be difficult for those new to do-it-yourself auto repair, but the auto-adjusting belt tension system and convenient belt routing diagram printed near the radiator make this an encouraging challenge.
Tools Used: Tools, Serpentine belt, Ratchet-wrench set
Install Serpentine Belt
Refer to the serpentine belt routing diagram printed near the radiator, and locate the tensioner pulley. It is usually located on the passenger side of the engine. For Chevrolet models without the routing diagram on the radiator support, refer to the owner’s manual for proper routing of the serpentine belt. Some Chevrolet models may also require removal of the air intake duct so you can access the tensioner pulley.
Feel the tension on the old serpentine belt to understand how much to tighten the new belt once it is fit into place.
