GMC Sierra Thermostat Housing Kit - Wehrli - LML - Brizzle Blue - '11-'16. This direct-replacement housing fits 2011–2016 GMC Sierra models with the 6.6L Duramax LML and brings a clean Brizzle Blue finish to your engine bay.

Built by Wehrli Custom Fabrication (WCFab), this unit installs in the factory location and replaces the OEM thermostat housing without altering surrounding components. The durable custom powder coat stands up to heat and grime while matching other WCFab parts under the hood. It's a straightforward way to refresh the front of the engine and tie together upgrades like WCFab intake kits, intercooler piping, upper coolant pipes, and coolant tanks—especially when paired with the WCFab Upper Coolant Pipe in the same color.
