Wehrli 11-16 Chevrolet 6.6L LML Duramax OEM Placement Coolant Tank Kit - Gun Metal

When you're working on your 2011-2016 Chevrolet Silverado or GMC Sierra with the 6.6L LML Duramax engine, you'll notice the factory plastic coolant reservoir isn't exactly a showpiece. This kit from Wehrli Custom Fabrication gives you a well-built, fabricated aluminum coolant tank that mounts right in the original location, making it a straightforward replacement. It's designed to dress up your engine bay and offer a more robust solution than the stock plastic tank.

What you get in this kit is a custom powder-coated aluminum coolant tank, finished in a sharp gunmetal color. It also includes a black anodized billet aluminum cap that's CNC machined for a precise fit, a coolant level sight glass so you can easily check your fluid level at a glance, an overflow hose, and the crucial low coolant level sensor. This means you're not just getting a good-looking part; you're getting a functional upgrade that uses the factory mounting points and requires no other modifications to install. It's designed to work with stock trucks, making the installation process manageable with basic hand tools.

Replacing the factory GM part numbers (like 22866587 or 22769155) with this kit means you're opting for a more durable and aesthetically pleasing component. It’s a solid choice if you’re looking to clean up the appearance of your engine bay while ensuring your cooling system functions properly.
