Wehrli L5P Duramax Thermostat Housing - Kiwi Green

When you're working on the cooling system of your 2017-2025 6.6L Duramax Silverado 2500 HD or 3500 HD, or its GMC Sierra counterparts, replacing the thermostat housing is a good opportunity to clean up the engine bay. The factory housing can look a bit plain, and this option from Wehrli offers a direct replacement that adds a custom touch.

This housing is powder coated in a vibrant Kiwi Green finish, designed to complement other WCFab upgrades you might have or plan to install, like their intake kits or intercooler piping. It's a straightforward swap for the OEM part, meaning it fits right in without any fabrication needed. The powder coat not only looks good but also helps protect the housing.

If you're looking to give your Duramax engine bay a more personalized and tidy appearance, this thermostat housing is a solid option. It's a simple way to make a noticeable difference in how your engine compartment looks, especially when paired with other matching WCFab components.
