Wehrli 20-24 Chevrolet-GMC 6.6L L5P Duramax OEM Placement Coolant Tank Kit - CAT Yellow

Starting with the custom powder coat finish in CAT Yellow, this Wehrli coolant tank kit is built to replace the factory plastic reservoir on your 2020-2025 Chevrolet Silverado 2500 HD or 3500 HD, and GMC Sierra 2500 HD or 3500 HD with the 6.6L L5P Duramax engine. It’s designed to mount directly in the original location, using the factory mounting points, so you won't need to modify anything on your truck to install it. This makes it a straightforward way to dress up your engine bay and swap out that often-cloudy plastic tank for something much more robust and visually appealing.

Beyond just looks, this tank is made from fabricated aluminum, which is a strong material that holds up well. It includes a coolant level sight glass, so you can easily check your coolant level at a glance without having to remove the cap. You also get a low coolant level sensor, which is a smart addition that helps prevent potential engine damage by alerting you if the level gets too low. The kit comes complete with a black anodized billet aluminum cap, an overflow hose, and all the necessary mounting hardware, making it a complete package for a clean installation.

This kit replaces GM part numbers 23394082 and 84622147. It’s designed for an easy installation using basic hand tools, meaning you can likely tackle this yourself without needing specialized equipment. If you're looking to clean up the appearance of your engine bay and add a more durable coolant reservoir, this Wehrli kit is a solid option.
