High-Quality Coolant Tank Upgrade for 6.6L Duramax

If you’re tired of staring at that faded, yellowed plastic coolant tank every time you pop the hood, this upgrade is for you. The Wehrli OEM Placement Coolant Tank Kit gives your 2020–2025 L5P Duramax the finished, high-end engine bay it deserves—with durability to match. Designed to mount in the factory location using OEM hardware, this tank replaces the stock reservoir with a fabricated aluminum unit that’s built to last and finished in your choice of custom powder coat colors. You’ll get a clear view of coolant levels thanks to the integrated sight glass, and the included low coolant level sensor ensures your warning systems keep working just like stock. The billet aluminum cap is black anodized for a clean, aggressive look and threads on with precision thanks to its CNC-machined construction. Everything you need to install is included—from hardware to the overflow hose—and the process can be handled with basic hand tools.
