Do you leave your car running to bleed a clutch?

No, you typically do not need to leave your car running to bleed a clutch. Bleeding a clutch involves pumping the clutch pedal to expel air from the hydraulic system, which can be done with the engine off. However, some mechanics prefer to run the engine briefly to ensure the master and slave cylinders are functioning properly after bleeding. Always consult your vehicle's manual for specific instructions.
