Wehrli 11-16 Chevrolet 6.6L LML Duramax OEM Placement Coolant Tank Kit - Illusion Purple

This fabricated aluminum coolant tank kit from Wehrli Custom Fabrication is built for your 2011-2016 Chevrolet Silverado 2500 HD or 3500 HD, or its GMC Sierra counterpart, when equipped with the 6.6L LML Duramax diesel engine. It's designed to mount directly in the factory coolant tank's location, making installation straightforward without needing other modifications. The kit replaces the often unappealing factory clear plastic reservoir with a custom-finished aluminum tank that really dresses up your engine bay.

The tank itself is constructed from aluminum and features a durable Illusion Purple powder coat finish for a unique look. A key feature is the integrated coolant level sight glass, allowing you to easily check your coolant level at a glance. It also includes a low coolant level sensor to alert you if the fluid gets too low, and a black anodized billet aluminum cap for a solid feel and secure seal. The kit comes complete with an overflow hose and all necessary mounting hardware, utilizing the factory mounting points for a direct fit installation with basic hand tools.

This kit is a great way to upgrade the appearance of your Duramax engine bay while maintaining the functionality of the factory cooling system. It replaces GM part numbers 22866587, 22769155, 22810003, 25869265, 22820166, 22957038, and 23106015.
