Here's a general outline. Specific details may vary slightly depending on your engine (3.1L V6 or 3.4L V6). Always consult a repair manual specific to your year and engine for precise instructions and diagrams. A Haynes or Chilton manual is a good investment.
Tools You'll Need:
* New serpentine belt: Get the correct belt for your specific engine. The part number is usually printed on the old belt. Auto parts stores can help you find the correct one.
* Socket wrench set: You'll need various sizes, likely including a ratchet, extensions, and possibly universal joints for better access.
* Wrench set: For any bolts or nuts that might require a wrench.
* Jack and jack stands: Crucial for safety. Never work under a car supported only by a jack.
* Wheel chocks: To prevent the car from rolling.
* Gloves: To protect your hands.
* Safety glasses: To protect your eyes.
* Pliers: Possibly needed to help with belt routing.
* Belt tensioner tool: This tool is usually *required* to release tension on the tensioner pulley to remove and install the belt. There are several different types of tools, and some can be rented from auto parts stores. Improvising may damage the tensioner.
* Flashlight: To see in tight spaces.
General Steps:
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks. Raise the front of the car using the jack and securely support it with jack stands.
2. Locate the Serpentine Belt: Identify the serpentine belt. It's the long belt that runs around various pulleys on the engine.
3. Identify the Tensioner: Locate the tensioner pulley. This is the pulley that needs to be relieved of tension to remove and install the belt. It might have a bolt that can be loosened or a lever to be pressed/moved.
4. Release Belt Tension: This is the most critical step. Use the appropriate tensioner tool to release the tension on the belt tensioner. This will allow you to slip the belt off the pulleys. Consult your repair manual for the correct procedure for your specific tensioner. Forcing it without the right tool can cause damage.
5. Remove the Old Belt: Once the tension is released, carefully work the belt off of each pulley, starting with the tensioner pulley.
6. Install the New Belt: Route the new belt onto the pulleys in the same order as the old belt. Again, your repair manual will have a diagram showing the correct routing. Pay close attention to the direction the belt runs.
7. Release Tensioner Tool: Once the new belt is on all the pulleys, carefully release the tensioner tool.
8. Check Belt Tension: Ensure the belt is properly tensioned. It should have a slight amount of give when pressed with your thumb. Consult your repair manual for specifications if available.
9. Lower the Car: Carefully lower the car using the jack.
10. Start the Engine: Start the engine and check for any squealing or slipping. If you hear any unusual noises, turn the engine off immediately and re-inspect your work.
Important Considerations:
* Diagram: Find a diagram of your specific engine's serpentine belt routing. Getting the routing wrong can cause engine damage.
* Tensioner: Be absolutely sure you are using the correct method to release the tensioner. Damaging the tensioner is an expensive mistake.
* Manual: A repair manual is invaluable for this job. It will provide detailed instructions, diagrams, and torque specifications.
Again, if you're not comfortable performing this repair, take your car to a qualified mechanic. It's much safer and less likely to lead to further damage to your vehicle.
