Tools You'll Need:
* New serpentine belt: Get the correct size and type for your specific Cavalier engine (2.2L or 2.4L). The part number is usually found on the old belt or through an auto parts store lookup using your VIN.
* Wrench(es): You'll likely need various sizes depending on the tensioner and other components.
* Socket set: Helpful for getting to hard-to-reach bolts or nuts.
* Ratchet: To make wrench work easier.
* Pliers: Possibly for adjusting the belt routing if necessary.
* Gloves: To protect your hands.
* Jack and jack stands (optional but highly recommended): For safer access and to reduce strain.
* Shop rags or paper towels: For cleaning.
Steps:
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. Disconnect the negative battery terminal to prevent accidental shorts. If you jack up the car, use jack stands to support it securely.
2. Locate the Serpentine Belt: It's the large belt that runs around various engine pulleys (alternator, power steering pump, water pump, etc.).
3. Identify the Belt Tensioner: This is a pulley with a mechanism to adjust belt tension. It usually has a bolt or a lever to release tension.
4. Release Belt Tension: This is the crucial step. Using the appropriate wrench(es) or socket, loosen the tensioner. This will usually involve turning a bolt or lever. Consult a repair manual or online video specific to your Cavalier's engine for the correct procedure – this step varies significantly between models. The tensioner may have to be loosened slightly for the belt to come off.
5. Remove the Old Belt: Once the tension is released, the belt should easily slip off the pulleys. You may need to slightly pry it off with a flat-head screwdriver, but be gentle to avoid damage.
6. Inspect Pulleys and Belt Routing: Examine the pulleys for wear or damage. Note the routing of the old belt carefully before discarding it; this is vital for correct installation of the new belt. Often, a diagram is printed on the underside of the engine cover.
7. Install the New Belt: Carefully align the new belt with the pulleys, following the same path as the old belt. Make sure the belt is seated correctly in each pulley groove.
8. Re-tighten the Tensioner: Once the belt is fully seated, re-tighten the belt tensioner to its proper position. Again, consult your manual for the correct torque. You should feel a slight amount of resistance when turning the belt.
9. Check Belt Tension: Try to twist the belt between two pulleys. It should only have a slight give.
10. Reconnect the Battery Terminal: Reconnect the negative battery terminal.
11. Start the Engine: Start the engine and listen for any unusual noises or squealing from the belt. Check for leaks. If you hear anything, shut the engine off and double check your work.
12. Double-Check: After a short drive, re-check the tension and look for any signs of the belt slipping or rubbing.
Important Considerations:
* Repair Manual: A repair manual specific to your 2001 Chevy Cavalier is invaluable. It will provide detailed diagrams, torque specifications, and step-by-step instructions.
* Online Videos: Searching YouTube for "2001 Chevy Cavalier serpentine belt replacement" can provide helpful visual guidance. However, always cross-reference with your owner's manual.
* Professional Help: If you're uncomfortable performing this task yourself, take it to a qualified mechanic. Incorrect installation can damage the engine.
