GMC Sierra Thermostat Housing Kit - Wehrli - Billet - Brizzle Blue - '08-'10. A top-outlet thermostat housing and upper coolant pipe kit for 2008-2010 GMC Sierra Duramax LMM.

This Wehrli kit replaces the OEM upper radiator hose that crosses the driver-side valve cover and the coolant return pipe, rerouting flow upward and forward from the thermostat. The layout improves access to driver-side fuel components and adds room for larger turbochargers. Includes coolant pipe, silicone boots, T-bolt clamps, and a CNC-machined billet aluminum upper housing in Brizzle Blue. Compatible with factory VGT turbos; required when using race-cover or SXE turbos in the valley. Available for single or twin CP3 setups. Not compatible with 2006-2007 models.
