  • This is a dual purpose Heat Exchanger and oil cooler for the 4.2L diesel for all years the engine was manufactured.
    • This part has a copper nickel core which is the reason it is more expensive than the other part listed which you can find by clicking here ==> 31212003.

      • The heat exchanger is complete and ready to install.
    • This part is made with OEM equivalent materials and is guaranteed for fit and function.
