Tools You'll Need:
* New serpentine belt: Make sure you get the correct size and type. Your owner's manual or an auto parts store can help with this.
* Socket wrench set: You'll likely need various sizes, including a wrench to possibly loosen the tensioner pulley.
* Wrench (possibly) for the tensioner pulley. The type depends on the Cavalier's specific tensioner. Some use a bolt, others have a different mechanism.
* Gloves: To protect your hands.
* Jack and jack stands (recommended): This gives you better access and safety. Never work under a car supported only by a jack.
* Ratchet: To help with the socket wrench.
* Optional: Belt routing diagram: A diagram showing the correct path of the belt around all the pulleys. You can usually find one online or in a repair manual.
Steps:
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. If jacking up the car, use jack stands properly. Disconnect the negative battery terminal to prevent accidental shorts.
2. Locate the Serpentine Belt: Identify the serpentine belt. It's the long, ribbed belt that runs around multiple pulleys.
3. Identify the Tensioner Pulley: This is the pulley that needs to be loosened to remove the old belt. It usually has a bolt or other mechanism to adjust its tension. The location and type vary slightly between engine types in the Cavalier.
4. Loosen the Tensioner: Use the appropriate wrench to loosen the tensioner pulley. This will create slack in the belt, allowing you to remove it. Be careful! The tensioner spring will try to snap back, so be prepared for some force. Sometimes you need to use a ratchet and a wrench simultaneously.
5. Remove the Old Belt: Carefully remove the old belt from around the pulleys.
6. Inspect Pulleys and Components: While the belt is off, inspect the pulleys for damage or wear. Check the belt routing to confirm you understand the path.
7. Install the New Belt: Carefully route the new belt onto the pulleys, following the same path as the old belt. Make sure it sits correctly in the grooves of each pulley. Consult your owner's manual or a routing diagram to ensure the correct order.
8. Tighten the Tensioner: Once the new belt is in place, slowly release the tensioner pulley. The belt should be snug. Do not overtighten.
9. Check Belt Tension: Make sure the belt is properly tensioned. You should be able to push it down about ½ inch in the middle of the longest span. If it's too loose or too tight, adjust the tensioner accordingly.
10. Reconnect Battery: Reconnect the negative battery terminal.
11. Test the Engine: Start the engine and listen for any squealing or unusual noises. If there are noises, double-check the belt routing and tension. If the noises continue, the belt may be faulty, or another component might require attention.
12. Lower the Vehicle (if applicable): If you used a jack, carefully lower the vehicle to the ground.
Important Considerations:
* Engine Type: The 1994 Chevy Cavalier came with different engine options. The exact procedure for loosening the tensioner might vary slightly depending on the engine.
* Repair Manual: A repair manual specific to your Cavalier year and engine is highly recommended. It will have detailed diagrams and instructions.
* Professional Help: If you're uncomfortable performing this task, it's best to seek help from a qualified mechanic. Incorrect installation can lead to belt failure and potential engine damage.
Remember, this is a general guide. Always refer to your owner's manual and/or a repair manual for your specific vehicle model before attempting any repairs. Safety should always be your top priority.
