ANOTHER Oil Cooler Question
Pulled the oil cooler from my 7.3 apart today to clean it up and put in new O-Rings. I had previously figured out that the PO had put some sealer in the radiator but it didn't dawn on me until I Looked that the same sealer would plug the oil cooler. Pretty obvious now, I just hadn't put the two together before. So, now I have to figure out a way to clear the water passages.
My first thought was to run a piece of drill rod through the water passages and push the sealer out. Then follow with some solvent to clean the walls of the tubes.
My question for the list is how careful I need to be about cleaning/flushing the main tube. It looks to be a pretty robust assembly, I doubt if I'm going to hurt anything, but I also don't want to assume that a good solvent rinse will work and then end up with a dead motor either. Can I put this tube in my parts washer and give it a good scrub?
Thanks in advance.

I would do the solvent, leave the rod in your tool box.
Right now I am brain dead, but I think I remember something about the coolant passages having an odd shape to help absorb more heat.

Sounds like a good bath is in order.
