Wehrli 06-10 Duramax LBZ/LMM Thermostat Housing Kit - Kiwi Green

With this Wehrli thermostat housing kit, you get the billet aluminum upper thermostat housing, the upper coolant pipe, silicone boots, and T-bolt clamps. This kit is designed to replace the factory upper radiator hose that typically crosses over the driver side valve cover, along with the coolant return pipe. It reroutes the coolant flow to an upward and forward path from the thermostat. This updated routing is a big help for accessing fuel system components on the driver's side of the engine, and it creates more space for larger aftermarket turbochargers. Plus, it gives your engine bay a cleaner, more modern look. This kit fits a range of Duramax trucks, including models like the 2006-2010 Chevrolet Silverado 2500 HD and 2007-2010 GMC Sierra 3500 HD.

The main housing is CNC machined from billet aluminum, making it a solid and well-built component. The custom powder coat finish in Kiwi Green not only adds a unique visual element but also helps protect the aluminum. This setup is compatible with factory VGT-style turbochargers and is also required if you're installing race cover style or S400/SXe turbochargers mounted in the valley. You can choose between configurations for single or twin CP3 fuel pump setups, depending on your specific needs. This kit is a popular choice for those looking to clean up their engine bay and improve access for other modifications.
