Wehrli 01-07 Chevrolet 6.6L LB7/LLY/LBZ Duramax OEM Placement Coolant Tank Kit - Bengal Blue

Wehrli Custom Fabrication is known for building tough, reliable parts for diesel trucks, and this coolant tank kit is no exception. If you're looking to clean up the engine bay on your 2001-2007 Chevrolet Silverado or GMC Sierra with the 6.6L Duramax diesel (LB7, LLY, or LBZ engines), this kit is a great way to replace that factory plastic coolant reservoir with something much more durable and visually appealing. It’s designed to mount right in the original location, making the swap straightforward.

This kit replaces the stock, often cloudy or yellowed, plastic tank with a fabricated aluminum one that's finished in a sharp Bengal Blue powder coat. You get a built-in coolant level sight glass so you can easily check your fluid level at a glance, and it even includes a low coolant level sensor to alert you if things get too low. The cap is a black anodized billet aluminum piece, and the kit comes with the necessary overflow hose and mounting hardware. It uses the factory mounting points, so no extra modifications are needed to install it on stock trucks.

This kit is a solid option for anyone wanting to improve the look and durability of their Duramax engine bay. It includes everything you need to swap out the old plastic tank for this well-built aluminum unit, including the cap, sensor, and hose. Just remember to refer to the manufacturer's installation instructions for any specific details during the swap.
