Chevrolet Duramax LMM Thermostat Housing Kit - Wehrli - Dual CP3 - Brizzle Blue - 06-10. This billet top-outlet housing and upper coolant pipe re-routes the OEM upper radiator hose and return pipe on 2006-2010 LBZ/LMM trucks for a cleaner, more serviceable layout.

By directing coolant upward and forward from the thermostat, the kit clears the area over the driver-side valve cover, improving access to fuel system components and creating room for larger aftermarket turbochargers. Designed for WCFab Dual CP3 systems and compatible with dual alternator setups, it remains compatible with factory VGT turbos and is 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. Brizzle Blue finish.
