Replace oil cooler or ok for 3k plus road trip????????

I am suspect of a bad oil cooler on my early 03 6.0L. I am getting normal temps around town but as soon as I get on the highway I am seeing a 20-30* difference in ECT-EOT. I get about 178-180 on my ECT and anywhere from 190-210 on my EOT. The later of the 2 being the highway driving unloaded. When towing it see 210+ up to 220. The temps here are 20-30f.

I am not seeing any oil in the coolant or vise versa. I am waiting my UOA to come back from black stone but for the past 3 test I have not had any coolant present in my oil. I assume that these temps have been this way for some time but only was able to see it when I installed my insight.

I would like some feed back from some techs on what I should do. I am going on a road trip on 2-19 and would like to get this straightened out before then. I have two issues. A possible ICP w/o codes and this oil cooler issue.


If I need to replace the cooler I would like to know if anyone has any pdf files of the shop manual on removing whatever needs to come out for the oil cooler. I had the egr delete done but tech never mentioned oil cooler plus I didnt even think of it at the time so shame on me.


If anyone has some advice and shop manual print outs it is greatly appreciated

its a straight forward repair. turbo and intake must come off. once out of the way I think its nine 10 mm bolts removed from the oil cooler housing and it will lift off. the repair kit you buy from ford has instructions with photos included from international. give her hell and get it done before you go on your trip.
