Chevrolet Silverado Thermostat Housing Kit - Wehrli - Dual CP3 - Flat Black - 06-10. Built for 2006–2010 LBZ/LMM Duramax trucks with WCFAB Dual CP3, this top-outlet billet housing and upper coolant pipe reroutes coolant cleanly.

It replaces the OEM upper radiator hose that crosses the driver-side valve cover and the coolant return pipe, redirecting flow upward and forward from the thermostat. The new path improves access to driver-side fuel components, adds space for larger aftermarket turbos, and supports dual alternator setups. Required with race-cover or SXE turbos in the valley. Compatible with factory VGT; not compatible with PPE dual fueler kits or 2006–2007 GMC Sierra. Flat Black finish. Replaces GM 19330105, 15792824, 25833204, 97361881.

• CNC-machined billet aluminum thermostat upper housing
