This radiator is built as a direct OEM primary replacement for the 2013-2018 RAM 2500 6.7L Cummins , allowing for hassle-free installation with no need for cutting, bending, or altering your vehicle. Its construction includes plastic end tanks and an aluminum core to replicate the original cooling capabilities. Stock radiators often succumb to wear over time, leading to leaks, clogs, or cracking at plastic connections. Keep your engine cool and running smoothly with this reliable replacement, which, like all Mishimoto products, comes protected by the Mishimoto Lifetime Warranty.
