Replacement Thermostat and Housing. Effectively restore function to your truck's cooling system by replacing a damaged thermostat with this thermostat and housing kit. The product is a housing with a thermostat installed within it, and it's simple to replace. The thermostat kit is made for select Chevy Silverado 1500 trucks and is a reliable replacement part that doesn't require any modifications to use.

Tough Build Design. The exposed housing of this thermostat is made from industrial-grade aluminum that's resistant to weathering and can withstand impacts over time. The thermostat is designed to hold up to long-term use, thanks to its tough design.

Basic Installation. Replacing the original thermostat housing with this product is a simple process that requires unbolting the original part and pushing this product into its place before bolting it in. Mechanics take 30-90 minutes to complete this installation.

Efficient and Affordable Design. The thermostat relies on sealed wax pellets to determine when the engine is hot and when it's cool. The wax controls whether the thermostat valve is open or closed and whether coolant can transfer between the radiator and the engine, and whether it's trapped in the engine block.
