My clutch won't engage 1997 Honda civic


Clutch plate and pressure plate seem to be too weak to pull the car. To test the clutch plate, park the car on flat surface. Pull the hand brake up, start the car, depress the foot brake pedal, depress the clutch pedal, put the car in 1st gear, press the gas pedal and leave the clutch pedal at once, while keeping the brake pedal depressed.
Follow one of the two following statements:
1. Engine does not shut down and remain start. (Clutch plate, pressure plate and clutch bearing defective - Replace all as a set)
2. Engine shuts down. (Clutch system is OK and does not require any repair).

Try different location on the clutch pedal to get it to start


If you look above the clutch pedal you should be able to see the operating switch, depress clutch pedal and see that there is clearane between the pedal and switch, It may be loose or require adjustment, the other option is to remove terminal block and bridge the terminals, this will delete the need for the switch and also the need to depress the pedal to start the motor, Regards Mike

How to bleed the slave cylinder


Same as bleeding brakes. Have someone depress the clutch pedal and hold it while another opens the bleeder on the slave cylinder; and close the bleeder before the clutch pedal is released. If a helper is not available to depress the clutch you can run a hose from the bleeder to a container with enough fluid in it to keep the hose covered, then slowly pump the clutch pedal until the air is out of the cylinder.
