Wehrli 11-16 Chevrolet 6.6L LML Duramax OEM Placement Coolant Tank Kit - Chevy Orange

If you're looking to clean up the engine bay of your 2011-2016 Chevrolet Silverado or GMC Sierra 2500/3500 HD with the 6.6L LML Duramax engine, this fabricated aluminum coolant tank kit from Wehrli Custom Fabrication is a solid choice. It directly replaces the factory plastic coolant reservoir, which can often become cloudy or brittle over time, with a much more robust and visually appealing aluminum unit. This kit is designed to mount in the original location, using the factory mounting points, making installation straightforward.

The tank itself is constructed from durable aluminum and finished in a striking Chevy Orange powder coat, giving your engine bay a custom look. A notable feature is the integrated coolant level sight glass, which allows you to easily check your coolant level at a glance without needing to remove the cap. It also includes a low coolant level sensor to alert you if the level drops too low, helping to prevent potential engine damage. The kit comes complete with a black anodized billet aluminum cap, overflow hose, and all necessary mounting hardware, ensuring you have everything needed for a clean installation with basic hand tools.

This Wehrli coolant tank kit is a direct replacement for several GM part numbers, including 22866587 and 22769155, and requires no other modifications to install on stock trucks. It’s a great way to add a custom touch while improving the longevity and serviceability of your cooling system.
