Mishimoto 2019+ Ram 6.7L Cummins Expansion Tank - Natural

The factory expansion tank on your 2019 and newer Ram 2500 or 3500 with the 6.7L Cummins engine is often a weak point in an otherwise tough cooling system. Over time, the stock plastic tank can become brittle, leading to cracks, discoloration, and internal breakdown from constant heat cycles. Mishimoto's aluminum expansion tank is built to address this issue head-on, offering a robust solution that lasts. Its TIG-welded aluminum construction is designed to withstand high temperatures and demanding use, ensuring long-term reliability.

Installation is straightforward, as this expansion tank is made to fit directly in place of the original unit. You won't need to drain the entire cooling system for the swap, and no special tools are required. Mishimoto includes all the necessary provisions for your factory sensors, including an OEM-style level sensor that keeps your truck's stock low coolant warning system working just as it should. This natural finish tank also gives your engine bay a cleaner, more finished look, and can be customized further with powder-coating, anodizing, or hydro-dipping.

This expansion tank is backed by the Mishimoto Lifetime Warranty, offering peace of mind for this considered purchase.
