Should I replace oil cooler??

I am about to do a coolant flush with ELC coolant and adding a coolant filter. Two questions, should I add the filter before I flush or at the same time? Also should I replace the oil cooler? Im at 140,000 and it hasn't been touched. I hear that flushing the coolant can clog it? Also if I should replace it how hard is it? Thanks!!

I know this was almost a given with 6.0. If you flushed with chemicals you ran the risk of your oil cooler clogging shortly after. Not sure about the 6.4. I would just watch oil and coolant temps to make sure they stay in range after the flush. I usually have a steady 3 to 4 degree difference when between ECT and EOT when unloaded.

I did the chemical flush and change to elc at about 95,000 miles. I did not clog my oil cooler. My delta stayed to about 2-4* difference. I would not change the oil cooler unless you need to. After the flush just keep an eye on your coolant and oil temps. I can imagine the oil cooler is a PITA to change. Also just so you know BPD is coming out with an external oil cooler like the one for the 6.0.

Just curious, I will be instsalling my mini maxx and will have the oil and coolant as one of the monitors to watch. What are the normal tamps for the oil and coolant? Thanks

My temps are usually 194 coolant and 196 oil. That is not towing and just cruising.

Thank you, is there a specific temp range for the oil and coolant?

Not sure what the acceptable delta is but I would say when it starts getting closer to a double digit spread then I would start getting concerned. unloaded of course
