Interesting, their website does not show a radiator for an eco diesel. More info?I replaced my rad after the stock rad sprun a leak where the plastic attaches to the core. I replaced with a cold case radiator part number R117437. It's a 3 core and has a rad cap. All aluminum. Fitment is 100 percent. My engine runs cooler and my engine oil temp runs cooler then my coolant temp. Never did that with the stock radiator.
I purchased the radiator from americantrucks website. The rad is a perfect fit. the only difference is the rad cap.
