Wehrli 20-24 Chevrolet-GMC 6.6L L5P Duramax OEM Placement Coolant Tank Kit - Fine Texture Black

If you're looking to clean up the engine bay on your 2020-2025 Chevrolet Silverado 2500 HD or 3500 HD, or your GMC Sierra 2500 HD or 3500 HD with the 6.6L L5P Duramax engine, this fabricated aluminum coolant tank kit from Wehrli Custom Fabrication is a solid option. It's designed to mount right in the factory location, meaning you won't need to modify anything on your truck to install it. This kit replaces that often unsightly clear plastic coolant reservoir with a custom powder-coated aluminum tank that looks much better under the hood.

This kit comes with everything you need to make the swap. You get the aluminum coolant tank itself, which features a fine texture black powder coat finish for durability and a clean look. It also includes a built-in coolant level sight glass so you can easily check your fluid level at a glance. A low coolant level sensor is integrated to alert you if the level drops too low, and the kit is topped off with a black anodized CNC machined billet aluminum cap and an overflow hose. It uses the factory mounting points, making installation straightforward with basic hand tools.

Replacing the OEM plastic tank with this aluminum version not only improves the appearance of your engine bay but also offers a more robust solution. The kit is designed as a direct replacement for GM part numbers 23394082 and 84622147, ensuring a proper fit for your L5P Duramax.
