Wehrli 20-24 Chevrolet-GMC 6.6L L5P Duramax OEM Placement Coolant Tank Kit - WCFab Grey

This kit gives you a fabricated aluminum coolant tank designed to fit right into the factory location on your 2020-2025 Chevrolet Silverado 2500 HD or 3500 HD, or your 2020-2025 GMC Sierra 2500 HD or 3500 HD with the 6.6L L5P Duramax engine. It's a great way to replace the standard, often cloudy, plastic coolant reservoir with something that looks much sharper under the hood.

The tank itself is made from aluminum and finished in a WCFab Grey powder coat, which helps it stand up to the engine bay environment. It comes with a black anodized billet aluminum cap that's CNC machined for a solid feel, a coolant level sight glass so you can easily check your fluid level, and the necessary mounting hardware. You also get an overflow hose and a low coolant level sensor, so you can retain that factory warning light functionality. This setup uses the original mounting points and requires no other modifications to install, making it a straightforward upgrade with basic hand tools.

This kit replaces GM part numbers 23394082 and 84622147. It's a well-built piece that not only dresses up your engine bay but also offers a more durable alternative to the stock plastic tank.
