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
