Mishimoto aluminum expansion tank for 2019+ Ram 6.7L Cummins replaces the factory plastic unit with a TIG‑welded reservoir that increases durability and cooling stability. Internal baffles reduce air pockets and coolant slosh, and provisions for factory sensors include an OEM‑style level sensor so warning systems keep working. Offered in a natural finish for customization and covered by Mishimoto’s Lifetime Warranty, it installs as a direct replacement.
