The GMC Sierra Thermostat Housing Kit by Wehrli is an optimal upgrade for any 2001-2005 LB7/LLY Duramax engine. This kit features a high-quality, billet CNC machined construction, finished in a striking Candy Teal color. Designed to replace the OEM upper radiator hose and the coolant return pipe, it provides both functional improvements and a refreshed appearance for your engine bay.

This kit re-routes the coolant to an upwards and forward configuration from the thermostat, enhancing accessibility to driver-side fuel system components. It allows for more space, accommodating larger aftermarket turbochargers. Plus, it's compatible with both Single and Dual CP3 Pump setups, and works seamlessly with factory VGT style, race cover style, or SXE turbochargers mounted in the valley. The robust CNC Machined Billet Aluminum construction ensures durability and longevity, while the custom two-stage powder coating adds a unique touch, available in a vibrant Candy Teal shade.
