Product Description

The **Mishimoto R2957-MT Replacement Radiator** is a direct-fit OEM-style cooling solution engineered for **2007-2018 Jeep Wrangler JK and Wrangler Unlimited JK** models equipped with the 3.8L or 3.6L engines. As radiators age, plastic tanks and cores can develop leaks, clogging, or structural issues that reduce cooling efficiency and can lead to overheating. This Mishimoto radiator replaces the original unit with **an aluminum core and factory-spec plastic end tanks** that integrate seamlessly with stock hoses, mounts, and accessories - requiring no cutting, bending, or modification for installation.

Designed to match OEM cooling performance and durability, this radiator maintains proper engine temperature under daily driving or light off-road conditions. With ~1.5" inlet/outlet connections and a crossflow design, it promotes even coolant distribution through the engine bay. Backed by **Mishimoto's Lifetime Warranty**, the R2957-MT unit is ideal for Jeep owners restoring cooling capacity after a failure or seeking a reliable OE replacement without performance losses.
