Is There an Oil Cooler I Can Use on my 2003 Ford F-350 Super Duty 6.0 Diesel

Updated 12/29/2025 | Published 12/05/2025

Question:

i am looking at your Derale oil cooler. I filled in my vehicle as a 2003 f350 super duty king ranch but no place for engine. It is a 6.0 diesel and not a gasser. Which ones will fit, Also if the oem factory cooler which is prone to plug up plugs up, it seems the oil flow to the oil filter and Derale ports will be cut off. If so can I get around this or just bypass the factory cooler? Also if I mount the cooler in front of the radiator. Wouldnt it cut down the radiator cooling for the engine?

Thanks for reaching out, Doug.

I did a bunch of searching and research on this for you to find an answer. Based off the information that I was able to find it looks like we don't carry a cooler that has ever been installed or fitted for your model of truck. I did double check with Derale and they don't show any confirmed fitments either.

Usually what this means is that the manufacturer hasn't done any fitment testing for your truck or when they did they were not able to get anything to work based off how your system is set up. It's very possible that something we carry would work, we just can't confirm fitment.

I also did some checking to see if it is possible that there is a cooler out there and it looks like there is, but they are more of a custom kit that is specific for your model. What we carry is more universal but it seems like your system needs more of a custom kit.

Sorry I don't have anything I can offer as a solution.

Hey Doug, were you able to find a custom oil cooler setup that works with your 6.0 diesel? Knowing what solution you went with could really help others trying to upgrade their F-350’s cooling system.
