Tools and Materials Needed:
- Jack stands
- Wheel chocks
- 10 mm wrench
- 7 mm wrench
- Catch container for old fluid
- Clutch fluid reservoir cap
- New DOT3 or DOT4 brake fluid
Steps:
1. Safety First: Engage the parking brake, chock the wheels of your truck, and position it on level ground.
2. Open the Clutch Fluid Reservoir Cap: Locate the clutch fluid reservoir cap, which is usually labeled, and remove it.
3. Top Up the Reservoir Fluid: Check the clutch fluid reservoir and ensure that it is filled to the appropriate level. Add DOT3 or DOT4 brake fluid as required.
4. Attach Catch Container: Connect a clear plastic hose to the clutch slave cylinder's bleeder valve (usually located on the side of the transmission near the clutch housing). Place the other end of the hose into a clear container suspended below. This allows you to observe and collect the expelled air and fluid.
5. Jack the Truck: Using the jack stands, slightly lift the front end of the truck to provide easier access to the bleeder valve.
6. Loosen the Bleeder Valve: With a 10 mm wrench, loosen the clutch bleeder valve to allow the fluid and air inside to exit.
7. Press and Hold the Clutch Pedal: Ask an assistance to press down the clutch pedal firmly and hold it.
8. Monitor the Fluid Flow: While the clutch pedal is held, observe the catch container and watch for air bubbles exiting through the hose from the bleeder valve.
9. Close the Bleeder Valve: Once you see only clutch fluid flowing (without air bubbles) into the catch container, your assistant should keep holding the clutch pedal down while you tighten the bleeder valve.
10. Release the Clutch Pedal: Ask your assistant to slowly release the clutch pedal.
11. Repeat the Process: Repeat the steps of loosening the bleeder valve, pressing the clutch pedal, and closing the valve until no more air bubbles are visible.
12. Check Fluid Levels: Keep checking the clutch fluid level in the reservoir and replenish as required to prevent it from going too low.
13. Ensure Proper Pedal Feel: After bleeding, release the clutch pedal. It should feel firm and spring back smoothly when you press it down.
14. Clean-Up and Inspection: Clean up any spilled clutch fluid and inspect for leaks. Address any leaks, if present.
15. Reinstall the Reservoir Cap: Replace the reservoir fluid cap securely.
16. Test the Clutch: Take the truck for a test drive to see if the clutch engages smoothly and effectively.
Bleeding the clutch on your 1999 2500 truck is an essential maintenance procedure that helps remove air from the hydraulic system. Ensure you use fresh clutch fluid and follow the steps carefully to ensure optimal clutch performance. If you encounter any issues during the process or have concerns about the clutch system, consult with a professional mechanic.
