1. Safety First: Ensure the vehicle is parked on level ground, the engine is turned off, and the handbrake is engaged.
2. Locate the Bleed Screw: The bleed screw for the clutch system is typically located on the clutch slave cylinder. It is often made of metal with a small rubber cap.
3. Gather Supplies: You will need a clear plastic tube, a wrench, and a container to catch the old fluid.
4. Attach the Tube: Connect one end of the transparent tube to the bleed screw and place the other end in the container to collect the old fluid.
5. Open the Bleed Screw: Use the wrench to loosen and open the bleed screw slightly.
6. Press the Clutch Pedal: Ask an assistant to press down the clutch pedal firmly and hold it down.
7. Open and Close the Bleed Screw: While the clutch pedal is held down, briefly open and close the bleed screw several times. This will help push air bubbles out of the system along with the old fluid.
8. Watch the Fluid: Observe the fluid flowing through the tube. You should see bubbles at first and then gradually just fluid as the air is purged.
9. Monitor the Clutch Pedal: Ask your assistant to pay attention to the clutch pedal's resistance as you open and close the bleed screw. The pedal should feel firmer as air is removed.
10. Repeat the Steps: Continue opening and closing the bleed screw while the assistant operates the clutch pedal, repeating the process until no more bubbles are visible in the tube, and the clutch pedal feels solid and responsive.
11. Close the Bleed Screw: Once you no longer see air bubbles, close the bleed screw tightly to prevent any further fluid loss.
12. Refill the Clutch Fluid: Open the clutch fluid reservoir cap and top up the fluid to the recommended level using DOT4 brake fluid compatible with your vehicle.
13. Test Drive: Take the Vivaro van for a test drive to ensure the clutch engages smoothly and without any issues.
14. Re-Check Fluid Level: After the test drive, re-check the clutch fluid level in the reservoir and adjust it if necessary.
Remember, brake and clutch systems deal with hydraulic pressure and safety; if you are not comfortable performing these steps or encounter any issues, it's best to consult with a qualified mechanic or refer to your Vivaro van's specific repair manual for more detailed instructions.
