Product Details

What It Helps Address

• Coolant temperature that runs outside the factory thermostat range
• Leaking or worn thermostat housing service points
• Delayed engine warm-up after thermostat wear
• Cooling system service on GM trucks, SUVs, and performance cars
• Replacement of a housing assembly that no longer seals correctly

Installation Notes

Install with a new gasket or seal, since the seal is required and not included. Mounting hardware is not included. Verify the 187°F specification, housing style, and vehicle application before installation. This assembly uses a mechanical actuator and two mounting holes, so clean the mating surfaces carefully and inspect the cooling system for contamination before reassembly.

Quality Assurance

Manufactured by an OE supplier using OEM-quality materials, OEM specifications, and controlled processes. The housing is built to meet safety standards expected in factory-style cooling system service.
