Product details

Motorad’s Integrated Housing Thermostat line focuses on OE-style replacement parts for modern cooling systems that use a combined thermostat and housing design. The 1011-180 is manufactured to OEM specifications and processes, with a copper case and wax compound that reacts quickly to coolant temperature changes. That helps maintain stable engine operating temperature in vehicles such as the Chevrolet Malibu, Pontiac G6, Saturn Aura, and Cadillac XTS, where precise thermal control is important for drivability and cooling performance.

This part cross-references Dorman - OE Solutions 902-693 and Wix 51011 for the same application. The silver housing includes a bleeder hole, jiggle pin, and metal gasket/seal to support proper coolant flow and air bleeding during service.

What it helps address

• Engine running too cool or too hot due to thermostat wear
• Coolant leaks at the thermostat housing interface
• Air trapped in the cooling system after service
• Delayed warm-up or unstable operating temperature
• Replacement needs on integrated thermostat housing designs

Installation notes and tips

Verify the 180°F temperature specification and outlet-port layout before installation. Clean the mating surfaces thoroughly, inspect the cooling system for contamination, and follow the vehicle service procedure for coolant refill and air bleeding. The included bleeder hole and jiggle pin help with purge during installation, but the system still requires proper bleeding to avoid trapped air.
