Wehrli 11-16 Chevrolet 6.6L LML Duramax OEM Placement Coolant Tank Kit - Bengal Grey

When you're working on your 2011-2016 Chevrolet Silverado or GMC Sierra with the 6.6L LML Duramax engine, you've got a few options for cleaning up the engine bay. This kit from Wehrli Custom Fabrication gives you a fabricated aluminum coolant tank that mounts right where your factory plastic one sits. It’s a great way to replace that often-cloudy or yellowed plastic reservoir with something that looks much sharper and is built to last.

What you get in this kit is a well-built aluminum coolant tank finished in a durable Bengal Grey powder coat. It includes a clear sight glass so you can easily check your coolant level at a glance, and it also comes with the necessary low coolant level sensor to keep your dash lights working as they should. The cap is a black anodized, CNC machined billet aluminum piece, and the kit also includes the overflow hose and all the mounting hardware needed for installation. Since it uses the factory mounting points and is designed for OEM placement, it fits right onto stock trucks without needing any other modifications.

Installation is straightforward and can be done with basic hand tools, making it a manageable project for many DIYers. This kit replaces several GM part numbers, including 22866587 and 22769155, offering a clean, custom look for your Duramax engine bay.
