GMC Sierra Thermostat Housing Kit - Wehrli - Sparkle Bomber Orange (2011–2016). A direct-replacement upgrade for the 6.6L Duramax LML that refreshes the engine bay with a durable, standout finish.

Built by Wehrli Custom Fabrication, this housing swaps in for the factory unit and pairs cleanly with other WCFab under-hood upgrades like Intake Kits, Intercooler Piping, Upper Coolant Pipes, and Coolant Tanks. The Sparkle Bomber Orange powder coat resists heat and corrosion while tying your build together—especially when matched with a WCFab Upper Coolant Pipe. It’s a straightforward, quality part that looks right and fits like stock.
