Chevrolet 4500 Coolant Tank Kit - Wehrli - Fabricated Aluminum, OEM Placement, WCFab - Red (2019+). This premium reservoir replaces the stock plastic tank with a robust, serviceable aluminum unit built for long-term reliability.

Built for L5D Duramax 4500 trucks, the WCFab tank mounts in the factory location with included hardware. The OEM reservoir often yellows over time and its molded-in sensor can trigger false low-coolant warnings. This kit addresses both issues with a fabricated aluminum body, a high-quality, serviceable float-type level sensor, a black anodized billet cap, and a billet sight glass for quick checks. The durable red powder coat resists corrosion, and the kit includes an overflow hose. Made in the USA.
