How to Replace the Serpentine Belt on a 1989 Chevrolet Celebrity

The serpentine belt, often referred to as a drive or accessory belt, rotates the pulleys of the accessory systems in your 1989 Chevrolet Celebrity. Serpentine belts wear down after several thousand miles of use. One of the first signs that the serpentine belt is wearing down is a loud squeak coming from your engine. Replace the serpentine belt when it wears down to keep the accessory systems in your engine running efficiently.

Tools Used: Metric wrench set, Replacement serpentine belt

Replace Serpentine Belt

Locate the tensioner pulley in the engine compartment. The tensioner pulley sits in between the alternator and crankshaft pulleys and is used to keep the serpentine belt tight. A bolt sits in the middle of the tensioner.

Place a wrench on the tensioner pulley bolt and rotate the pulley to the left. The belt will loosen on all of the pulleys.

Remove the belt from one of the pulleys and rotate the tensioner back to the right. (It's easiest to take the belt off the alternator or tensioner pulleys.)

Pull the belts off the other pulleys and discard the belt. The 1989 Chevrolet Celebrity has six pulleys: alternator, power steering, water pump, air conditioning, crankshaft and tensioner.

Find the accessory belt diagram in the engine compartment and use it as a guide for replacing the serpentine belt (see Resources)--the engine will not run right if the belt is not placed on the pulleys in the same order.

Route the belt around the pulleys according to the belt diagram, leaving the alternator or tensioner open.

Move the tensioner pulley to the left, wrap the belt around the final pulley and rotate the tensioner back to its original position. The belt will tighten around the other pulleys.

Tips & Warnings

Make sure the serpentine belt sits in the center groove of each pulley. If it is not properly situated, the belt will not drive the accessory systems, or it will create a loud squealing noise.
