Product Details
When you're working on the cooling system of your 2017-2025 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD, replacing the thermostat housing is a straightforward way to clean up the engine bay. This housing from Wehrli is a direct replacement for the factory part, but with a custom touch.
It's powder coated in a vibrant Cat Yellow, which really makes the engine compartment pop, especially when paired with other Wehrli Fabrication (WCFab) upgrades like their intake kits or coolant pipes. The powder coat finish not only looks good but also offers a durable surface that resists corrosion better than a standard painted or bare metal housing.
This part is designed to fit right in place of your original, making the installation simple. It's a popular choice for Duramax owners looking to add a bit of personal style to their truck's engine bay.
