Here's a general guide. Specific steps may vary slightly depending on your engine (2.2L or 2.4L). Consult a repair manual specific to your Cavalier's year and engine for precise instructions and diagrams.
Tools You'll Need:
* Socket wrench set (likely need a 7mm and possibly a 10mm or 13mm depending on the distributor hold down bolt)
* Pliers or a screwdriver (depending on the type of distributor hold-down clamp)
* New distributor cap and rotor
* Flashlight (to see inside the distributor)
* Wire brush (optional, for cleaning distributor terminals)
Steps:
1. Locate the Distributor: The distributor is usually located on top of the engine, near the firewall (the partition between the engine compartment and the passenger compartment). It's a cylindrical component with several wires connected to it.
2. Disconnect the Ignition Wires: Carefully remove the ignition wires from the distributor cap. Make a note of where each wire goes (a diagram or photo is helpful). Some people use a marker to number the wires and cap terminals. It's crucial to reconnect them correctly.
3. Remove the Distributor Cap: Once the wires are disconnected, you can carefully remove the distributor cap by gently pulling it straight up. Sometimes it might be a little stubborn. Avoid twisting it forcefully.
4. Remove the Rotor: The rotor is the small, spinning component inside the distributor cap. It's usually held on by friction. You should be able to simply pull it off.
5. Inspect the Distributor: Inspect the distributor for any signs of damage or wear. Clean the contact points inside the distributor cap and on the distributor body with a wire brush if necessary.
6. Install the New Rotor: Carefully install the new rotor, ensuring it's properly seated.
7. Install the New Distributor Cap: Carefully place the new distributor cap onto the distributor, ensuring that it aligns correctly with the rotor.
8. Reconnect the Ignition Wires: Reconnect the ignition wires to the distributor cap, making sure each wire goes back into the correct terminal, matching your notes or diagram.
9. Reinstall the Hold Down: Re-attach the distributor hold down clamp, ensuring it's secure.
10. Reconnect the Battery: Reconnect the negative battery terminal.
11. Test: Start the engine and listen for any unusual noises or misfires. Check for any error codes. If the engine runs rough, double-check that all ignition wires are correctly connected. If problems persist, you may need professional help.
Important Considerations:
* Repair Manual: A repair manual specific to your 1998 Chevy Cavalier is highly recommended. It will provide detailed diagrams and instructions.
* Engine Type: The process might be slightly different depending on the specific engine in your Cavalier (2.2L or 2.4L).
* Safety: Always disconnect the negative battery terminal before working on the ignition system.
* Professional Help: If you're uncomfortable performing this repair yourself, take your car to a qualified mechanic.
This is a general guide. Improper installation can lead to engine damage. If you are not comfortable with automotive repair, it's best to take your vehicle to a qualified mechanic.
