Wehrli 11-16 Chevrolet 6.6L LML Duramax OEM Placement Coolant Tank Kit - CAT Yellow

This fabricated aluminum coolant tank kit from Wehrli Custom Fabrication is built to replace the factory plastic coolant reservoir on your 2011-2016 Chevrolet Silverado 2500 HD or 3500 HD, or GMC Sierra 2500 HD or 3500 HD equipped with the 6.6L LML Duramax diesel engine. The factory plastic tank can become brittle and discolored over time, but this aluminum unit offers a much more robust and visually appealing solution for your engine bay. It's designed to mount directly in the original location, using the factory mounting points, so you won't need to modify your truck to install it.

The tank itself is constructed from aluminum and finished with a durable custom powder coat in CAT Yellow, giving your engine bay a clean, custom look. A notable feature is the coolant level sight glass, which makes it easy to 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 fluid gets too low, helping to prevent engine damage. To top it off, it comes with a black anodized billet aluminum cap, an overflow hose, and all the necessary mounting hardware. This kit is designed to be a straightforward upgrade using basic hand tools.

This kit replaces several GM part numbers, including 22866587 and 22769155, offering a direct replacement for a worn or unsightly original tank. It's a solid option if you're looking to dress up your engine bay and gain a more reliable coolant reservoir.
