Wehrli 20-24 Chevrolet-GMC 6.6L L5P Duramax OEM Placement Coolant Tank Kit - Sparkle Copper

When you open the hood of your 2020-2025 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD with the 6.6L L5P Duramax engine, you'll get a custom coolant tank kit from Wehrli. This kit replaces the factory clear plastic coolant reservoir with a fabricated aluminum tank that mounts in the original location. It's designed to dress up your engine bay and give it a much cleaner look than the stock component.

The tank itself is made from aluminum and finished in a custom sparkle copper powder coat. It includes a coolant level sight glass so you can easily check your fluid level at a glance, and a low coolant level sensor to alert you if it gets too low. The kit also comes with a black anodized billet aluminum cap and all the necessary mounting hardware, plus an overflow hose. This setup uses the factory mounting points and installs easily with basic hand tools, meaning no other modifications are needed for it to fit right on your stock truck.

This Wehrli coolant tank kit is a solid option if you're looking to improve the appearance of your engine bay. It directly replaces GM part numbers 23394082 and 84622147, and supersedes WCF100679.
