The Mishimoto aluminum expansion tank for 2019 and newer Ram 6.7L Cummins engines offers a robust upgrade to the factory plastic reservoir, which can become brittle and prone to cracking over time. Crafted from TIG-welded aluminum, this tank delivers exceptional durability and heat resistance, ensuring reliable performance under demanding conditions. Its internal baffles help maintain optimal coolant flow, prevent air pockets, and reduce coolant starvation, contributing to more consistent engine cooling and enhanced reliability. Installation is straightforward, with a direct fit replacing the stock unit without the need to drain the entire cooling system. All necessary provisions for factory sensors are included, including an OEM-style level sensor that preserves the truck’s low coolant warning system. This feature allows seamless integration with the vehicle’s existing diagnostics, providing peace of mind during everyday driving. The natural finish offers a sleek, clean look, and can be further customized through powder-coating, anodizing, or hydro-dipping to match your truck’s aesthetic. Backed by Mishimoto’s lifetime warranty, this expansion tank is designed to withstand high temperatures and heavy use while adding a polished appearance to your engine bay, making it both a functional and aesthetic upgrade for your Ram Cummins diesel engine.
