Description
The Mishimoto aluminum expansion tank designed specifically for 2019 and newer Ram 6.7L Cummins trucks offers a durable upgrade over the factory plastic tank. Constructed from TIG-welded aluminum, this expansion tank withstands high temperatures and heavy-duty use without cracking, discoloration, or internal degradation that can occur with plastic over time. Internal baffles help maintain coolant stability during demanding driving conditions, reducing the risk of air pockets and coolant starvation that can compromise engine cooling performance. This ensures your engine runs efficiently and reliably, even under tough operating conditions. The tank includes an OEM-quality level sensor, allowing the vehicle’s low coolant warning system to function seamlessly, preserving safety features without modification. Installation is straightforward as the Mishimoto tank fits directly in place of the factory unit without requiring draining the entire cooling system, and no special tools are necessary. All necessary provisions for factory sensors are included, making the upgrade clean and hassle-free. Beyond performance and durability, this expansion tank enhances the engine bay’s appearance with a sleek, natural finish that can be customized with powder coating, anodizing, or hydro-dipping for a personalized look. Designed for longevity and aesthetic appeal, the Mishimoto 2019+ Ram 6.7L Cummins expansion tank is backed by the Mishimoto lifetime warranty, providing confidence in its quality and durability. Whether replacing an aging component or upgrading for performance, this aluminum tank is an excellent choice for serious Ram owners looking for a reliable, long-lasting solution that maintains your vehicle’s cooling system integrity.
