Tools You'll Need:
* New Power Steering Belt: Make sure you get the correct size. Your owner's manual or a parts store can help with this.
* Wrench(es): You'll likely need a wrench to loosen the power steering pump pulley. The size will depend on your Jeep; consult your owner's manual or look at the bolt head.
* Socket Wrench Set: Helpful for accessing bolts more easily.
* Crescent Wrench or Adjustable Wrench: A good backup if you don't have the exact size wrench.
* Socket Extension(s): May be needed for better reach.
* Gloves: Protect your hands.
* Jack and Jack Stands (highly recommended): Safely lifting the Jeep will give you better access and more comfortable working space. Never work under a vehicle supported only by a jack.
* Wheel Chocks: To secure the Jeep.
* Pry Bar (optional but helpful): For loosening stubborn pulleys.
* Shop Rags: To clean up any grease or dirt.
Steps:
1. Safety First: Park your Jeep on a level surface, engage the parking brake, and chock the rear wheels. 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 Power Steering Belt: The power steering belt is usually located on the front of the engine, often running between the crankshaft pulley and the power steering pump pulley.
3. Loosen the Power Steering Pump Pulley: Locate the bolt in the center of the power steering pump pulley. Use the appropriate wrench to loosen this bolt. You might only need to loosen it, not completely remove it, depending on how the belt is routed.
4. Loosen (or remove) the Belt Tensioner (if applicable): Some 1989 Wranglers have an automatic belt tensioner. If yours does, you may need to use a wrench or socket to loosen the tensioner, allowing the belt to come loose. Others might have a manual tensioner that requires you to pry it with a bar, carefully, to release tension on the belt. Consult your repair manual for specifics on your model.
5. Remove the Old Belt: Once the tension is released, the belt should slip off the pulleys.
6. Install the New Belt: Carefully route the new belt onto the pulleys in the same path as the old belt. Make sure it sits correctly in all the grooves.
7. Tighten the Power Steering Pump Pulley (and/or tensioner): Tighten the bolt on the power steering pump pulley and the belt tensioner (if applicable) to the manufacturer's specified torque.
8. Lower the Jeep: Carefully lower the Jeep using the jack.
9. Check Belt Tension: Inspect the new belt to ensure it's properly seated and there's adequate tension. You should be able to push on the belt midway between pulleys with your thumb and it should deflect only slightly. Consult your repair manual for the correct tension specifications. If the tension is off, repeat steps 3-7.
10. Start the Engine: Start the engine and listen for any squealing or unusual noises. If you hear any squealing, the belt might be too loose or improperly routed. Turn off the engine immediately if you notice problems.
Important Considerations:
* Repair Manual: A Jeep Wrangler repair manual specific to your year and model is highly recommended. It will provide detailed diagrams, torque specifications, and other important information.
* Difficulty Level: This is a relatively easy repair, but if you're not comfortable working on your vehicle, it's best to take it to a mechanic.
* Belt Routing: Pay close attention to how the belt runs over the pulleys. Incorrect routing can cause problems.
* Torque Specifications: Tighten the bolts to the correct torque specification to avoid damage to the components.
This guide provides general instructions. Always consult your vehicle's repair manual for specific details and safety precautions. If you're unsure about any step, seek professional help.
