Wehrli 20-24 Chevrolet-GMC 6.6L L5P Duramax OEM Placement Coolant Tank Kit - Gloss White

Starting with a fabricated aluminum coolant tank that mounts directly in the factory location is a smart move for your 2020-2025 L5P Duramax. This kit from Wehrli Custom Fabrication replaces the standard, often cloudy, plastic coolant reservoir with a much cleaner-looking gloss white aluminum unit. It’s designed to use the OEM mounting points, so you won’t need to modify anything on your stock truck to get it installed.

What really sets this tank apart is the attention to detail. You get a built-in coolant level sight glass, so checking your fluid level is as simple as a quick glance, no more guessing. It also comes with a low coolant level sensor, just like the factory part, so your dash warning light will still function correctly. The cap is a black anodized, CNC machined billet aluminum piece, which adds a solid touch and complements the gloss white powder coat finish. This kit includes everything needed for installation, including the overflow hose and all necessary mounting hardware, making it a straightforward upgrade with basic hand tools.

Replacing the factory plastic tank with this aluminum version not only improves the appearance of your engine bay but also offers a more robust solution. It’s a well-built part that fits right in, giving your Duramax a custom look without any hassle.
