The GMC Sierra 3500 HD Coolant Tank Kit by Wehrli is a must-have upgrade for your 2011-2016 Duramax Diesel truck. Designed in Bengal Silver to seamlessly integrate into your engine bay, this kit replaces the factory plastic reservoir with a more durable and visually appealing fabricated aluminum tank.

This coolant tank kit not only improves the look under the hood but also enhances the functionality. The custom powder-coated aluminum construction resists rust and corrosion, providing a long-lasting solution that can withstand extreme engine bay temperatures. Additionally, it includes a sight glass for easy monitoring of coolant levels, and a low coolant sensor to alert you when it’s time for a top-up. The tank uses OEM mounting points, ensuring a perfect fit without the need for additional modifications, and it can be installed with basic hand tools.
