Wehrli Custom Fabrication WCF100196-GM Secondary Coolant Tank Kit

The Wehrli Custom Fabrication WCF100196-GM is a fabricated aluminum secondary coolant tank kit designed to replace the factory plastic reservoir with a durable, custom-finished upgrade. Mounts in the OEM location on the passenger side of the engine bay, retaining all factory hose connections and mounting points — no modifications to the truck are required.

Constructed from high-quality fabricated aluminum and finished in a custom powder coat, this tank adds a clean, professional look to the engine bay while delivering long-lasting durability over the factory plastic degas bottle. The included billet aluminum sight glass provides a quick and easy visual check of coolant level at a glance, without removing caps or covers.
