GMC Sierra Thermostat Housing Kit - Wehrli - Dual CP3 - Illusion Blueberry - 08–10. This top-outlet billet housing and upper coolant pipe reroute the factory hose for a cleaner layout on 2008–2010 Sierra Duramax builds using WCFab Dual CP3.

Routing coolant upward and forward from the thermostat frees access to driver-side fuel components and creates room for larger turbochargers. The CNC-machined upper housing is finished in Illusion Blueberry and the kit includes the coolant pipe, silicone boots, and T-bolt clamps. Compatible with factory VGT turbos and dual alternators; required when using race-cover or SXE turbos in the valley. Not compatible with PPE dual-fueler kits or 2006–2007 GMC Sierra. Replaces GM 19330105, 15792824, 25833204, 97361881.
