Product Details
The factory plastic auxiliary coolant reservoir on your 2020-2025 Duramax L5P can look a bit out of place. This kit from Wehrli Custom Fabrication replaces that clear plastic tank with a custom-fabricated aluminum one, finished in a sharp Bronze Chrome powder coat. It’s designed to mount in the OEM location using the factory mounting points, making installation straightforward with basic hand tools.
This kit includes a black anodized billet aluminum cap, CNC machined for a precise fit, and a preformed hose for the overflow flow fitting. The aluminum construction is more durable than the stock plastic, and the custom powder coating offers a clean, dress-up look for your engine bay. It’s a direct replacement for GM part numbers like 84211275, requiring no other modifications to install on stock trucks.
