Wehrli 20-24 Duramax L5P Auxiliary Coolant Tank Kit - Bengal Red

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 plastic reservoir for your fuel cooling system, giving your engine bay a much cleaner look. You get the main aluminum tank, a black anodized billet aluminum cap, the necessary mounting hardware, an overflow flow fitting, and a preformed hose.

The tank itself is made from aluminum and finished in a Bengal Red powder coat, which is a custom single-stage coating. This isn't just about looks, though; the aluminum construction is a solid upgrade from the stock plastic. It uses the factory mounting points, so it installs easily with basic hand tools without needing any other modifications to your truck. It's a direct replacement for GM part number 84211275.
