Wehrli 11-16 Chevrolet 6.6L LML Duramax OEM Placement Coolant Tank Kit - Sparkle Granny Smith

Starting with a custom powder-coated fabricated aluminum coolant tank, this kit from Wehrli Custom Fabrication is designed to replace the often-unattractive factory plastic coolant reservoir in your 2011-2016 Chevrolet Silverado 2500 HD or 3500 HD, or GMC Sierra 2500 HD or 3500 HD equipped with the 6.6L LML Duramax engine. The Sparkle Granny Smith finish adds a unique touch to your engine bay, setting it apart from stock. This tank is built to mount directly in the OEM coolant tank location, utilizing factory mounting points for a straightforward installation that doesn't require any other modifications to your truck.

Beyond just looks, this aluminum tank includes a coolant level sight glass, making it easy to check your coolant level at a glance without needing to remove the cap. It also comes with a low coolant level sensor to alert you if the level drops too low, helping to prevent potential engine damage. The kit is completed with a black anodized CNC machined billet aluminum cap, an overflow hose, and all necessary mounting hardware. This is a well-built upgrade that offers both improved aesthetics and functional benefits over the original plastic tank.

Installation is designed to be simple, requiring only basic hand tools. This kit directly replaces GM part numbers 22866587, 22769155, 22810003, 25869265, 22820166, 22957038, and 23106015, ensuring a proper fit for your specific application.
