How does this housing restore cooling system performance?

The thermostat housing directs coolant through the thermostat and radiator passages while providing a mounting point for the temperature sensor. Replacing a cracked or leaking housing prevents coolant loss and helps maintain proper engine operating temperatures by allowing the thermostat and sensor to operate correctly.

• Seals coolant passages to stop external leaks and pressure loss.
• Houses sensor to ensure accurate temperature readings for engine management.
• Matches factory thermostat position to preserve coolant flow dynamics.

What materials and build quality can I expect?

The WMPHE housing is manufactured from engineered materials sized and finished to reproduce OEM fitment. It is produced to withstand typical underhood heat and coolant exposure, and includes the sensor boss and mating flange surfaces machined to accept stock fasteners and gaskets.

• Durable molded material formulated for automotive coolant resistance.
• Precision mounting faces to reduce installation fuss and leaks.
• Preformed ports for original hose connections and sensor location.

What should I check before ordering and installing?

Always verify the correct part number and vehicle application before purchase. Confirm the OE reference on your old housing or use the "confirmed fit" tool in the product listing, and inspect hoses, thermostat, and clamps during replacement to ensure a reliable repair.

• Compare the old part number to 55565336, 55579010, 902-808, etc.
• Inspect adjacent hoses and replace clamps or thermostat if worn.
• Drain coolant and follow proper bleeding procedures after installation.

Who is this for: This WMPHE thermostat housing assembly is intended for DIY mechanics and professional technicians servicing compact GM vehicles that use the referenced OE parts. It’s a practical choice if your Cruze, Trax, Sonic, or Encore exhibits coolant leaks at the housing, temperature sensor faults, or you are performing scheduled cooling-system maintenance. Make sure to match the part numbers and confirm vehicle fitment before ordering to ensure a seamless replacement.
