Park the vehicle and engage the parking brake.
Locate the serpentine belt. It is the long, thin belt that runs across the front of the engine.
Find the belt tensioner. It is a small pulley located near the middle of the belt.
Insert a breaker bar or wrench into the tensioner and turn it counterclockwise. This will loosen the tension on the belt.
Remove the old belt.
Install the new belt. Start by looping it over the crankshaft pulley, then the tensioner pulley, and finally the alternator pulley.
Re-tension the belt. Use the breaker bar or wrench to turn the tensioner pulley clockwise until the belt is tight.
Start the engine and let it run for a few minutes. This will allow the belt to stretch and settle into place.
Check the tension of the belt again and adjust as necessary.
Here are some additional tips for replacing the serpentine belt on a 1994 Jeep Cherokee:
Use the correct size belt. The size of the belt is printed on the old belt.
Be careful not to over-tighten the belt. This can cause the belt to break.
If you are unsure about any of the steps, consult a qualified mechanic.
By following these steps, you can safely and easily replace the serpentine belt on your 1994 Jeep Cherokee.
