Dorman - First Stop Clutch Master Cylinder P/N:CM39931
Dorman CM640174 clutch master cylinder for the 2007-2010 Saturn Sky 4-cylinder 2.0L and other vehicles turns clutch pedal force into hydraulic pressure to release the clutch. Its design follows the original clutch master cylinder, so it works as a direct replacement.
Fluid around the clutch master cylinder, a soft or sinking clutch pedal, or a clutch that will not fully release can mean this clutch master cylinder is failing. These signs alone do not prove the clutch master cylinder is at fault, since a worn clutch slave cylinder can also be behind them.
This clutch master cylinder fits the 2007-2010 Saturn Sky 4-cylinder 2.0L and the 2007-2009 Pontiac Solstice 4-cylinder 2.0L, and each car takes one.
