Tools You'll Need:
* New serpentine belt: Make sure you get the correct size and type for your Jeep. The best way to ensure this is to check your owner's manual or the belt itself for part numbers before buying a replacement. Auto parts stores can cross-reference this information for you.
* Wrench(es): You'll likely need a few different sizes, depending on which tensioner your Jeep has. A socket wrench set is ideal.
* Socket wrench extensions: These will make access to some bolts easier.
* Ratchet: To turn the socket wrench.
* Gloves: To protect your hands.
* Jack and jack stands (highly recommended): Lifting the vehicle makes access much easier and safer. Never work under a vehicle supported only by a jack.
* Wheel chocks: For safety.
Steps:
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks to secure the vehicle. If jacking, lift the front of the vehicle and securely support it with jack stands. Disconnect the negative battery terminal.
2. Locate the Serpentine Belt: Identify the serpentine belt routing around the various pulleys (alternator, power steering pump, water pump, etc.). Trace its path carefully before removing it, as you'll need this information for reinstallation. Take a picture if it helps.
3. Identify the Tensioner: The tensioner pulley is what allows you to remove the belt. There are usually two types:
* Automatic Tensioner: This type is spring-loaded and usually has a bolt or lever that needs to be moved to release tension. Locate the tensioner (often near the alternator) and identify the bolt or lever. You'll use a wrench to loosen this bolt or lever, releasing tension on the belt.
* Manual Tensioner: This type usually requires turning a bolt to relieve tension on the belt.
4. Release Belt Tension: Use the appropriate wrench to loosen the tensioner bolt or lever. This will allow you to carefully slip the belt off the pulleys.
5. Remove the Old Belt: Once tension is released, carefully pry the belt off the smallest pulley first (usually the crank pulley). Work your way around until the belt is completely removed.
6. Install the New Belt: Starting with the smallest pulley, carefully position the new belt onto each pulley, following the same path as the old belt.
7. Tighten the Tensioner: Once the belt is on all pulleys, slowly tighten the tensioner bolt or lever until you feel sufficient tension on the belt. You should be able to slightly twist the belt midway between pulleys with your hand; it shouldn't be too loose or too tight. The exact amount of tension is sometimes tricky.
8. Check Belt Routing: Double-check that the belt is correctly routed around all the pulleys before lowering the vehicle.
9. Lower the Vehicle (If Applicable): Carefully lower the vehicle to the ground using the jack.
10. Reconnect the Battery: Reconnect the negative battery terminal.
11. Test: Start the engine and listen carefully for any squeaking or squealing noises, which could indicate incorrect tension or routing. Inspect the belt for proper movement and alignment.
Important Considerations:
* Belt Diagram: Find a diagram showing the belt routing for your specific year and engine. Many are available online.
* Tension: Incorrect tension can lead to premature belt failure or damage to other components. Consult your owner's manual for guidelines.
* Professional Help: If you're uncomfortable performing this task yourself, it's best to take your Jeep to a qualified mechanic.
This guide provides general instructions. Variations might exist depending on your specific 1992 Jeep Cherokee model. Always refer to your owner's manual for the most accurate and detailed instructions. Safety should always be your top priority when working on your vehicle.
