Chevrolet Duramax Thermostat Housing Kit - Wehrli - GM Duramax LML - Chevy Orange - 2011-2016. A direct-replacement housing that refreshes your LML’s cooling junction and adds a uniform Chevy Orange finish under the hood.

Built by Wehrli Custom Fabrication (WCFab), this housing replaces the OEM part on 2011–2016 6.6L LML trucks and pairs cleanly with WCFab intake kits, intercooler piping, the upper coolant pipe, and coolant tanks. The durable powder coat handles under-hood heat and regular cleaning, while factory-style fitment helps keep hose routing and serviceability familiar. It’s a straightforward way to tidy the bay and match existing WCFab hardware.
