How do you bleed the clutch sistem in a fiero car?

Bleeding the clutch system on a Pontiac Fiero is similar to bleeding brakes, but there are a few key differences. Because it's a hydraulic system, air in the lines will prevent the clutch from engaging properly. Here's how to do it, but always consult your Fiero's repair manual for specific details and torque specifications for your year and model. The procedure might vary slightly depending on the year.

Tools You'll Need:

* Clutch bleeding kit: This typically includes a clear hose, a wrench that fits your bleeder valve (usually 8mm or 10mm), and a container to catch the fluid.

* New clutch fluid: DOT 3 or DOT 4 brake fluid is generally suitable. Use the correct type recommended in your owner's manual.

* Wrench(es): To access the bleeder valve.

* Rags or shop towels: To clean up spills.

* A helper: This makes the process much easier.

* Funnel: To add fluid to the master cylinder reservoir.

Steps:

1. Locate the Bleeder Valve: The clutch bleeder valve is located on the slave cylinder, which is typically bolted to the transmission bell housing. It's often a small valve with a small hexagonal opening. You'll need to get under the car to access it. Consult your repair manual for the precise location.

2. Locate the Master Cylinder Reservoir: This is the reservoir that holds the clutch fluid. It's usually near the brake master cylinder.

3. Check the Fluid Level: Ensure the master cylinder reservoir is filled to the appropriate level with fresh DOT 3 or DOT 4 brake fluid.

4. Attach the Bleeding Kit: Attach one end of the clear hose to the bleeder valve and the other end to the container to collect the fluid. Make sure the hose is securely attached to prevent leaks.

5. Have Your Helper Ready: Your helper will need to pump the clutch pedal repeatedly.

6. Open the Bleeder Valve: Using the appropriate wrench, carefully open the bleeder valve about 1/4 to 1/2 turn.

7. Pump the Clutch Pedal: Have your helper slowly and firmly pump the clutch pedal several times. They should hold the pedal down on the last pump.

8. Close the Bleeder Valve: While the pedal is depressed, close the bleeder valve.

9. Release the Pedal: Have your helper release the clutch pedal.

10. Repeat: Repeat steps 6-9 several times until no more air bubbles are visible in the clear hose and the fluid runs clear.

11. Check and Refill: Top off the master cylinder reservoir as needed.

12. Test the Clutch: After bleeding, test the clutch engagement. The clutch pedal should feel firm and engage smoothly.

Important Considerations:

* Air in the System: If the clutch still feels spongy after bleeding, there might be more air trapped in the system, or you may have a leak. Re-bleed the system.

* Fluid Type: Using the incorrect fluid can damage the system.

* Safety: Wear safety glasses to protect your eyes from splashes of brake fluid. Brake fluid can damage paint, so be careful where you work.

* Manual: This guide is a general overview. Always refer to your Fiero's repair manual for the specific procedure for your model year.

If you're uncomfortable performing this task, it's best to take your Fiero to a qualified mechanic. Improper bleeding can lead to clutch failure.
