Chevrolet Silverado Thermostat Housing Kit - Wehrli - Dual CP3 - Kiwi Green - 06-10. A top‑outlet billet thermostat housing and upper coolant pipe that refines coolant routing on 2006–2010 Duramax LBZ/LMM trucks.

It replaces the factory upper hose over the driver-side valve cover and the coolant return pipe, routing coolant upward and forward from the thermostat. This layout improves access to driver‑side fuel components and frees space for larger aftermarket turbos.
