Wehrli 20-24 Chevrolet-GMC 6.6L L5P Duramax OEM Placement Coolant Tank Kit - Candy Teal

When you're looking to clean up the engine bay of your 2020-2025 Chevrolet or GMC 6.6L L5P Duramax truck, replacing that bulky, clear plastic coolant reservoir is a great place to start. This fabricated aluminum coolant tank from Wehrli Custom Fabrication mounts right in the factory location, making the swap straightforward. It's designed to give your engine bay a much cleaner, more custom appearance.

This tank isn't just about looks, though. It's built from aluminum and finished in a sharp candy teal powder coat, which holds up well to engine bay heat and grime. You get a built-in coolant level sight glass so you can easily check your fluid level at a glance, and it includes a low coolant level sensor to alert you if things get too low. The kit also comes with a black anodized billet aluminum cap, an overflow hose, and all the necessary mounting hardware. Since it uses the OEM mounting points and connects to factory lines, installation is pretty simple with basic hand tools.

This Wehrli coolant tank is a solid option if you're aiming for a more polished look under the hood. It directly replaces GM part numbers 23394082 and 84622147, and it fits on stock trucks without needing any other modifications.
