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

When you're looking to clean up the engine bay on your 2020-2025 6.6L L5P Duramax truck, replacing the factory plastic coolant reservoir is a great place to start. This fabricated aluminum coolant tank from Wehrli Custom Fabrication mounts right in the original location, making the swap straightforward. It's designed to dress up your engine bay with a custom, semi-gloss black powder coat finish that looks much cleaner than the stock clear plastic tank.

This kit isn't just about looks, though. It includes a coolant level sight glass so you can easily check your coolant level at a glance, and it also comes with a low coolant level sensor to keep you informed. The cap is a custom piece, CNC machined from billet aluminum and black anodized for a solid feel and durable finish. Everything you need for installation, including mounting hardware and an overflow hose, is included, and it uses the factory mounting points, so no other modifications are necessary. It's a well-built replacement that offers both improved aesthetics and practical functionality.

This Wehrli coolant tank is a direct replacement for GM part numbers 23394082 and 84622147, ensuring it's designed to integrate seamlessly with your truck's cooling system. Installation is designed to be simple, requiring only basic hand tools, making it an accessible upgrade for many Duramax owners.
