What you'll need:
* Clutch bleeding kit: This usually includes a clear hose and a suitable container to catch the old fluid. You can often adapt a brake bleeder kit for this purpose.
* New DOT 3 brake fluid: Never use anything else. DOT 3 is the correct spec for this vehicle.
* Wrench: The size will depend on your car, but it's likely a 10mm or 11mm for the bleeder screw on the slave cylinder.
* Container: To catch the old fluid.
* Jack and jack stands (optional but recommended): Easier access to the slave cylinder.
* Gloves: Brake fluid is corrosive.
* Clean rags: To wipe up spills.
Procedure:
1. Locate the clutch slave cylinder bleeder: This is usually located on the transmission housing near where the clutch line connects. It's a small screw with a valve. Consult a repair manual or online diagrams specific to your 2003 Cavalier for the precise location. This is crucial as the process varies slightly between manual transmission types.
2. Prepare the system: Open the hood. Top off the master cylinder reservoir with fresh DOT 3 brake fluid. Keep an eye on the fluid level throughout the bleeding process; it will drop.
3. Attach the bleeding kit: Attach one end of the clear hose to the bleeder screw on the slave cylinder. Submerge the other end of the hose into the container of brake fluid.
4. Have your helper pump the clutch pedal: Your helper should slowly and firmly pump the clutch pedal several times.
5. Open the bleeder screw: While your helper holds the clutch pedal down, carefully open the bleeder screw on the slave cylinder. You should see fluid flowing through the clear hose. Close the bleeder screw when your helper releases the pedal.
6. Repeat steps 4 and 5: Repeat this process several times until you see no more air bubbles in the fluid flowing through the hose. The fluid should flow steadily and consistently, free of air bubbles.
7. Check the master cylinder reservoir: Add more brake fluid as needed to keep the reservoir level topped up.
8. Check for leaks: Once you're finished, thoroughly inspect the system for any leaks around the slave cylinder, the master cylinder, and the clutch line.
9. Test the clutch: After completing the bleeding process, test the clutch pedal. It should feel firm and responsive with a normal engagement point.
Important Considerations:
* Gravity Bleeding (Alternative Method): If you don't have a helper, you can try gravity bleeding. This is slower but can be effective. Simply open the bleeder screw slightly and let the fluid drain slowly, while topping off the master cylinder reservoir as needed. This method requires more patience.
* Repair Manual: A repair manual specific to your 2003 Chevrolet Cavalier will provide diagrams and detailed instructions tailored to your specific vehicle. This is strongly recommended for accurate location of components and avoiding potential mistakes.
* Professional Help: If you are uncomfortable performing this procedure yourself, it is always best to take your vehicle to a qualified mechanic. Incorrectly bleeding the clutch can cause damage to the hydraulic system.
Remember to always work in a well-ventilated area, as brake fluid fumes can be harmful. Brake fluid is corrosive, so wear gloves and clean up any spills immediately.
