Wehrli 06-10 Duramax LBZ/LMM Thermostat Housing Kit - WCFab Grey

When you're working on your 2006-2010 Duramax LBZ or LMM, this Wehrli Custom Fabrication Thermostat Housing Kit in WCFab Grey gives you a cleaner coolant routing and better access. What you get in this kit is a CNC machined billet aluminum thermostat housing, a coolant pipe, silicone boots, and t-bolt clamps. This setup replaces the stock upper radiator hose that typically crosses over the driver side valve cover and the coolant return pipe, rerouting the coolant flow upwards and forward from the thermostat. This change is a big help for accessing fuel system components on the driver's side of the engine.

Beyond making maintenance easier, this kit is also designed to make room for larger aftermarket turbochargers, especially those with a race cover or SXE style. It's also compatible with factory VGT style turbochargers, so you don't have to change your turbo setup to benefit from the improved routing and engine bay appearance. The billet aluminum construction means it's well-built and ready for the demands of a Duramax engine, and the custom powder coat finish adds a clean look under the hood. This kit is a popular choice for those looking to upgrade their turbo setup or simply clean up their engine bay.

This kit is specifically designed for the 2006-2010 Duramax LBZ and LMM platforms, fitting a range of Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD trucks. It's a solid option if you're planning a turbo upgrade or need better access to your fuel system. Make sure to check the manufacturer's installation instructions for any specific details regarding the coolant system refill and bleeding process.
