When you press the clutch pedal, the clutch master cylinder turns that pedal effort into hydraulic pressure — and the Dorman First Stop Clutch Master Cylinder CM640174 is a direct-fit replacement for the 2007-2009 Pontiac Solstice and 2007-2010 Saturn Sky, both with the L4-2.0L engine.

  • Direct replacement: reverse-engineered from the original equipment to fit and function like the master it replaces.
  • Piston-type cylinder: 19 mm inside-diameter bore.
  • Durable materials: high-grade rubber components compatible with standard brake fluid.
  • Backed by value: supported by a team of engineers and quality control experts in the United States.

The body is black plastic. This unit does not include a reservoir and is not pre-bled or pre-filled, so you'll need to bleed the clutch hydraulic system after installation. A master cylinder that is leaking or malfunctioning, a soft or sinking clutch pedal, or difficulty disengaging the clutch can be signs this part may need replacing — diagnose the cause before replacing. Country of origin: Mexico.

Frequently Asked Questions

Will this clutch master cylinder fit my vehicle?

It's a direct-fit replacement for the 2007-2009 Pontiac Solstice and 2007-2010 Saturn Sky with the L4-2.0L engine. Check the Buyer's Guide tab to confirm your vehicle.

What does a clutch master cylinder do?

When you press the clutch pedal, it converts that effort into hydraulic pressure and sends fluid to the slave cylinder to disengage the clutch.

Does it include a reservoir or come pre-bled?

No — the reservoir is not included and the unit is not pre-bled or pre-filled, so you'll need to bleed the clutch hydraulic system after installation.

What fluid is it compatible with?

It uses high-grade rubber components compatible with standard brake fluid. Refer to your vehicle service information for the correct fluid specification.

What are signs mine may need replacing?

A leaking or malfunctioning cylinder, a soft or sinking clutch pedal, or trouble disengaging the clutch may be signs; diagnose the cause before replacing.
