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

When you're working on your 2020-2025 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD with the 6.6L L5P Duramax engine, you get a fabricated aluminum coolant tank, a coolant level sight glass, a custom powder coat finish in Sparkle Granny Smith, a low coolant level sensor, a billet anodized cap, an overflow hose, and all the necessary mounting hardware. This kit is designed to replace the factory plastic coolant reservoir, giving your engine bay a much cleaner and more custom look.

This Wehrli coolant tank is built from aluminum and powder-coated in a unique Sparkle Granny Smith finish, making it a standout piece under the hood. It mounts directly in the original coolant tank location, using the factory mounting points, so no other modifications are needed for installation. The integrated sight glass lets you easily check your coolant level at a glance, and the included low coolant sensor will alert you if the level drops too low, helping to prevent potential engine damage. The kit also comes with a black anodized billet aluminum cap and an overflow hose, completing the custom appearance.

Installation is straightforward and can be done with basic hand tools, making it an accessible upgrade for many truck owners. This kit directly replaces GM part numbers 23394082 and 84622147, and supersedes WCF100679. It's a solid option for anyone looking to dress up their engine bay while maintaining OEM functionality and ease of use.
