It is located between the engine and the gearbox. It is used to disengage the engine, which prevents the movement to be transmitted to the gearbox while the gear shifts are made. Roughly speaking, it is the piece that disengages the engine from the wheels when the driver presses on the clutch pedal.
Same problem. Pulley is spinning just fine but clutch won't engage. I also had an evap small leak and I read that the PCM does pre-checks before sending signal to a/c compressor but after fixing leak still no a/c. How to diagnose if clutch has gone bad or PCM won't send signal?
