Product Description

The CSF 3959 is an OEM-style engine coolant radiator engineered for the supercharged 6.2L V8 Hellcat powertrain as installed in the Dodge Durango SRT Hellcat (2021, 2023-2025) and Jeep Grand Cherokee Trackhawk (2018-2021). Built with an OEM-specified plastic tank and aluminum core in a cross-flow configuration, this radiator directly replaces Dodge/Jeep OEM part number 68365278AA and installs without modification. The B-Tube coolant passage design and multi-louvered fin array maximize heat transfer efficiency - essential for managing the thermal output of a supercharged V8 producing up to 710 hp in stock Durango Hellcat trim and 707 hp in the Grand Cherokee Trackhawk.

The shared 6.2L supercharged architecture between the Durango Hellcat and Grand Cherokee Trackhawk means a single CSF 3959 unit serves both platforms, covering all Durango Hellcat trim levels - standard, Premium, and Plus. Glass-filled engineered plastic tanks, EPDM rubber gaskets rated to -120°F, and factory-torqued assembly ensure long-term durability under the sustained heat cycling and high-load operating conditions typical of these vehicles. Each unit is individually nitrogen leak tested to 150% of operating pressure before leaving the factory.
