our d4 had a shagged oil cooler too so what the mechanics did was get a aftermarket transmission cooler for a Toyota land cruiser and mounted that in front of the rad as oil cooler cores are NLA from cat you can get a full rad core and gaskets though. they simply pulled the rad apart and resurfaced the flange faces with devcon and any corroded areas got the devcon treatment too then reassembled with new gaskets. the replacement cooler was plumbed to the factory ports on the engine. it works like a dream. we kept the oil cooler as we are in a hot climate. besides cat designed them with one so there was a reason.
the oil gauges on these old girls are only to indicate if oil pressure is too low and not the actual amount. I read in another post that as long as they have a minimum of 5 psi pressure at idle that is fine. the gauges are more like an oil pressure light on your car.
The way I did mine on the 5U was, since it had rust holes in the bottom tank, I put about 50 layers of POR-15 on it. Waiting for a sunny day to hook up the lines again to see if it will hold. Those oil coolers were deemed unnecessary but I quite like having original equipment in place. I might dink with it some more if it still leaks, such as making a new bottom tank

POR 15 is good stuff it's dearer than devcon epoxy adhesives and puttys and once cured devcon can be drilled, threaded or filed. i hope it works for you. remember it is only a anti corrosive paint not a filler. not sure how it would handle coolant and heat at the same time. their fuel tank sealer might be a good choice.
Yes, we'll see once I hook it back up. Won't shock me if it doesn't work : ), but I had the stuff on the shelf and it wasn't any bother to apply those layers over time.
Thank you all for your help! Do I need to check the pressure with a real gauge to make sure I didn't blow out the cooler with too much pressure. That is why I was hoping to get a top end cold pressure range. Thanks again! Elton
Cat just went with a wider core radiator and eliminated the oil cooler on later tractors.
