Tools You'll Need:
* New serpentine belt: Make sure you get the correct size and type. Your owner's manual or a parts store can help you identify the correct one.
* Wrench (likely 13mm and possibly others): To loosen the tensioner pulley. The exact size may vary; check your vehicle.
* Socket wrench set: Helpful for accessing and turning bolts, although open-ended wrenches often suffice.
* Jack and jack stands (highly recommended): This makes accessing the belt much easier and safer.
* Wheel chocks: Essential for safety when using a jack.
* Gloves: To protect your hands.
* Pen or marker (optional): To mark the belt routing before removal. Highly recommended for reinstallation.
* Pliers or needle-nose pliers (optional): Can be helpful for maneuvering the belt.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks. Jack up the front of the Jeep and securely support it with jack stands. Never work under a vehicle supported only by a jack.
2. Locate the Serpentine Belt: Identify the serpentine belt and trace its path around the various pulleys (alternator, power steering pump, water pump, etc.).
3. Locate the Belt Tensioner: This is a pulley with a mechanism to release tension on the belt. It often has a bolt you need to loosen or a lever to push/pull.
4. Release Belt Tension: This is the trickiest part. You'll need to use the appropriate wrench to loosen the tensioner's bolt. Some tensioners require you to use a wrench and leverage the tensioner; others use a pivot-style lever. As you loosen the tensioner, the belt should become slack enough to slip off the pulleys. *It's helpful to have a helper to maintain tension while you remove the belt.*
5. Remove the Old Belt: Carefully remove the old serpentine belt from the pulleys, working your way around the system.
6. Installation of the New Belt: This is where your markings (if you made them) come in handy. If you didn't mark the routing, carefully trace the belt path from the diagram in your owner's manual. Work the new belt onto the pulleys in the same order as the old one. Make sure the belt is seated correctly on each pulley groove.
7. Tighten the Tensioner: Once the new belt is fully seated, carefully tighten the tensioner bolt. You might need to gently work the belt around the pulleys while tightening the tensioner bolt to ensure the belt is properly seated.
8. Check Belt Tension: After tightening the tensioner, rotate the belt by hand to check if it is properly tensioned. There should be some tension, but it shouldn't be overly tight. A loose belt will squeal, and a too-tight belt can cause premature wear and damage to bearings.
9. Lower the Jeep: Carefully lower the Jeep to the ground.
10. Start the Engine: Start the engine and listen for any squealing noises. If you hear squealing, the belt tension might be incorrect or the belt might not be properly seated.
Important Notes:
* Consult a Repair Manual: A repair manual specific to your 2000 Jeep Wrangler will provide detailed diagrams and instructions.
* Safety First: Always prioritize safety. Use jack stands, never work under a vehicle supported only by a jack.
* Belt Routing: The exact routing of the belt might vary slightly depending on your specific engine options and accessories. Always double-check your owner's manual or a repair manual.
* Tension: Improper tension is a common mistake. Too loose and the belt will slip; too tight and it can put stress on the bearings and other components.
If you're uncomfortable performing this repair yourself, it's always best to take your Jeep to a qualified mechanic. This guide is for informational purposes only and doesn't replace professional advice.
