Wehrli L5P Duramax Thermostat Housing - Brizzle Blue

Wehrli is known for making well-built parts for Duramax trucks, and this thermostat housing is no exception. If you're working on your 2017-2025 6.6L Duramax Silverado or Sierra, this part is a direct replacement for the stock thermostat housing.

This housing is powder coated in a Brizzle Blue finish, which really helps clean up the look of your engine bay. It's designed to perfectly complement other WCFab upgrades, like their upper coolant pipes, intake kits, and coolant tanks, making it easy to build a cohesive look under the hood. It's a straightforward swap that makes a noticeable difference in appearance.
