Tools and materials needed:
- Wrench
- Phillips head screwdriver
- 10mm socket
- 14mm wrench
- Clear tubing (about 2 feet long)
- Container of DOT 3 or DOT 4 brake fluid
- Funnel
- Rags
Step-by-step instructions:
1. Prepare the vehicle. Park your 240SX on a level surface and turn off the engine. Allow it to cool down completely. Engage the parking brake and chock the wheels to prevent the vehicle from rolling.
2. Locate the clutch bleeder valve. The clutch bleeder valve is located on the underside of the vehicle, near the transmission. It is typically a small, brass-colored valve with a 10mm bleed screw.
3. Clean the bleeder valve. Use a wire brush or a rag to clean any dirt or debris from around the bleeder valve. This will help prevent any contaminants from entering the clutch system.
4. Attach the clear tubing to the bleeder valve. Slide one end of the clear tubing over the bleeder valve nipple. Make sure that the tubing fits snugly over the valve to prevent any leaks.
5. Place the other end of the tubing into a container of brake fluid. The container should be filled with enough brake fluid to cover the end of the tubing. Make sure that the container is positioned lower than the bleeder valve to allow gravity to help move the air bubbles out of the clutch line.
6. Open the bleeder valve 1/4 turn. Use the 10mm socket to open the bleeder valve 1/4 turn. You should see brake fluid and air bubbles coming out of the tubing.
7. Close the bleeder valve. Once the flow of brake fluid slows to a trickle, close the bleeder valve by turning it clockwise until it is snug.
8. Repeat steps 6 and 7 until no more air bubbles come out of the tubing. You may need to repeat this process several times to completely bleed the clutch line.
9. Top up the brake fluid reservoir. Once you are satisfied that all the air bubbles have been removed from the clutch line, top up the brake fluid reservoir to the "MAX" line.
10. Test the clutch. Start the engine and pump the clutch pedal several times. The pedal should feel firm and have good resistance. If the pedal feels soft or spongy, there may still be air in the system and you will need to repeat the bleeding process.
Note: Be sure to keep an eye on the brake fluid level in the reservoir during the bleeding process. If the reservoir runs low on fluid, air can be drawn into the system, which will necessitate repeating the bleeding process.
