GMC Duramax Thermostat Housing Kit - Wehrli - Billet - Sparkle Bomber Orange - 2001-2005. A top-outlet billet thermostat housing and upper coolant pipe kit for LB7/LLY trucks, finished in Sparkle Bomber Orange.

It replaces the OEM upper radiator hose over the driver-side valve cover and the coolant return pipe, routing flow upward and forward from the thermostat. This cleaner layout improves access to driver-side fuel components and creates room for larger aftermarket turbos. Compatible with Single and Dual CP3 setups and factory VGT turbos; required with race-cover or SXE turbos in the valley. CNC-machined billet aluminum upper housing with two-stage powder coat. Includes coolant pipe, silicone boots, and T-bolt clamps. Replaces GM 15792832 and 15198345. Made in the USA.
