Tools You'll Need:
* New serpentine belt: Make sure you get the correct size and type for your engine. A parts store can help you with this.
* Jack and jack stands: Essential for safe working conditions. Never work under a car supported only by a jack.
* Wrench set: Various sizes will likely be needed, depending on your specific tensioner design.
* Socket set: Again, you might need different sizes.
* Ratchet: To use with your sockets and wrenches.
* Pliers (optional): May be needed for some tensioner designs or to help route the belt.
* Gloves: To protect your hands.
* Safety glasses: To protect your eyes.
* Diagram or picture of the serpentine belt routing: This is CRUCIAL. Getting the belt routing wrong can lead to damage. You can usually find a diagram online or in a repair manual.
Procedure:
1. Safety First: Park the car on a level surface, engage the parking brake firmly, and chock the wheels. Raise the front of the car using a jack and securely support it with jack stands.
2. Locate the Serpentine Belt and Tensioner: Identify the serpentine belt and the tensioner pulley. The tensioner is the pulley that moves to allow belt removal and installation.
3. Release Tension: This is the most critical step. There are different types of tensioners:
* Spring-loaded tensioner: Often you'll need a wrench or socket to turn a bolt or lever on the tensioner to relieve pressure on the belt. This will usually allow you to remove the belt from one pulley. Consult a diagram to find the correct bolt/lever. *Some tensioners require a special tool.*
* Hydraulic tensioner: These are less common but work automatically; you may need to carefully pry the tensioner slightly or use a specialized tool.
4. Remove the Old Belt: Once the tension is released, carefully slip the belt off the pulleys. Note the routing carefully. Take pictures if needed.
5. Install the New Belt: Follow the routing diagram precisely! Carefully route the new belt onto each pulley, ensuring it sits correctly in the grooves of all pulleys.
6. Release Tensioner (if necessary): If you used a tool to release tension in step 3, you may have to maintain this pressure while routing the belt. Be extremely careful not to let the tensioner snap back, as this could cause injury.
7. Check Belt Routing: Double and triple-check that the belt is routed correctly before releasing the tensioner.
8. Re-engage Tensioner: Release the tensioner tool. The tensioner should automatically re-engage, putting the belt under proper tension.
9. Check Tension: After installing the belt, try to twist the belt with your hand. There should be some resistance, but you shouldn't be able to twist it easily.
10. Lower the Vehicle: Carefully lower the vehicle using the jack.
11. Start the Engine: Start the engine and listen for any squealing or unusual noises. If you hear squealing, the belt may be improperly routed or too loose.
Important Notes:
* Consult a repair manual: A repair manual specific to your 1998 Chevy Prizm will provide detailed instructions and diagrams.
* Diagram is crucial: Without a proper diagram showing the correct serpentine belt routing, you risk damaging your engine.
* Tension is key: Improper tension can lead to premature belt wear or failure.
* If you're unsure: If you're not comfortable performing this repair yourself, it's best to take your car to a qualified mechanic.
This guide provides general steps. The specifics may vary slightly depending on your engine. Always prioritize safety and refer to a repair manual for your specific vehicle for the most accurate instructions.
