The Chevrolet Duramax Thermostat Housing Kit from Wehrli, fitted with an Upper Coolant Pipe and finished in the stunning Illusion Blueberry, is an exceptional aftermarket offering for `01-`05 Duramax models. This kit is crafted to improve under-the-hood aesthetics and overall functionality by altering the coolant routing in your vehicle.

This product offers a practical solution to some of the usual constraints found in stock systems. The kit modifies the OEM upper radiator hose that generally crosses the driver side valve cover and the coolant return pipe. By changing the coolant routing to move upwards and forward from the thermostat, it provides improved access to driver side fuel system components, creates additional room for larger aftermarket turbochargers, and enhances overall engine bay appearance. The kit is compatible with both Single and Dual CP3 Pump setups and is a must for those using race cover style or SXE turbochargers in the valley.
