Detailed Product Description

The Dorman 902-2052 thermostat housing is engineered to meet the exact specifications required for Chevrolet and GMC models such as the Blazer, C10, C20, K5 Blazer, and various Suburban and pickup truck variants.

Installation Notes and Tips

When installing the Dorman 902-2052 thermostat housing, ensure the engine is cool to avoid injury from hot coolant. Use the included gasket to create a proper seal and prevent leaks. Verify that the 90-degree housing neck aligns correctly with the vehicle’s coolant hoses.

Tighten mounting bolts evenly to manufacturer torque specifications to avoid warping the housing.
