Wehrli 20-24 Chevrolet-GMC 6.6L L5P Duramax OEM Placement Coolant Tank Kit - Chevy Orange

Starting with a fabricated aluminum construction, this coolant tank kit from Wehrli Custom Fabrication 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. The Chevy Orange powder-coat finish offers a clean, custom look under the hood, moving away from the often-cloudy appearance of the stock plastic tank. This kit is designed to mount directly in the OEM coolant tank location, utilizing factory mounting points for a straightforward installation with basic hand tools, meaning no other modifications are necessary for it to fit right.

Beyond just looks, this kit includes practical features to keep you informed about your coolant level. A built-in coolant level sight glass lets you quickly check the fluid level at a glance, and it also comes with a low coolant level sensor to alert you if the level drops too low. The kit is completed with a black anodized billet aluminum cap for a solid feel and durability, an overflow hose, and all the necessary mounting hardware. This setup replaces GM part numbers 23394082 and 84622147, offering an updated and more robust solution for your Duramax L5P's cooling system.
