Product Details
This kit gives you a custom-fabricated aluminum auxiliary coolant tank for your 2020-2025 Duramax L5P truck. It's designed to replace the factory clear plastic reservoir that cools your fuel system, giving your engine bay a much cleaner look. You get the aluminum tank itself, a black anodized billet aluminum cap, and all the necessary mounting hardware to get it installed. It also includes a pre-formed hose and an overflow flow fitting.
Wehrli builds this tank from aluminum and finishes it with a fine texture black powder coating, which is a solid choice for durability and appearance. The cap is CNC machined from billet aluminum and then black anodized for a strong, corrosion-resistant finish. This kit is made to mount in the original location using the factory mounting points, so it fits right in without needing other modifications to your truck.
This auxiliary coolant tank is a direct replacement for GM part number 84211275. It's designed to install easily with basic hand tools, making it a straightforward upgrade to dress up your engine bay.
