Oil cooler leaking!
Well it just never fails fix one thing something else breaks!
So how much of a PITA is an oil cooler to do?
It sure don't look like it's going to be fun!

Pretty easy really, just a bit tedious. Just watch the front gasket when you are putting the cooler back on as it likes to slide out of place.
Two write-ups in the 7.3L PSD Tech Folder for your viewing. If that doesn't do it for you, there are dozens of videos on YouTube.
As for pressing the ends on, just keep them straight as not to break or crack them. Some have used cargo straps, others used large woodworking pipe clamps, others have used theirgirth strength to press them on. Use some assembly lube or something similar on the o-rings though, or they will tear or catch.
Use the OEM o-ring set, not the Felpro or Dorman sets.

Use some sort of lube on the o-rings before pressing the ends back on.
I've had the o-rings actually roll out of position when installed without lube, and you can end up not only blowing oil all over the place, but can also simultaneously get a big hot mess of coolant in the oil REALLY fast.

Did mine about three weeks ago. Managed to do it all, but a helper would have made it much easier when re-installing it.
My house is at end of road, sort of up on a hill, so people can't see what I'm doing..... so I bet my neighbors were wondering why I was screaming & cussing all day !

Leaking badly or just a minor drip spot when it sits overnight but seals back up when the motor is warm? Depending one where you live that might not be a real run repair in the middle of winter if you don’t have a shop to do it in.

Your welcome. Bob at Diesel-O-Rings is another good supplier of parts like this too.
As for the water pump, if it isn't broke (or leaking), don't fix it.
Let us know if you hit a snag, we are here to help.

A good friend of mine delayed his oil cooler job for 2 years by keeping it plugged in for a few months during winter. He is local to me here in north GA though, so the winters are very mild.
He said if he knew it was going to be that easy to replace (I helped him), he would have done it a lot sooner. He went with Felpro from a parts store against my advice, but so far so good.
