rebuilding my radiator brings up a ? on engine oil cooler

car- 72 280 se 4.5

i developed a tiny pin hole on my upper radiator. My initial plan was to rip the rad out and braze the hole shut --quick and easy to keep it on the road until i needed to do more complex surgery. Once i had the rad out though, some fins were looking weak showing green. For as many miles as i put on the car, it is just a matter of when it will blow out. Rather fix it now than have it blow out on me while making a 600 mile trip.

So my plan snowballed out of control already. Time to do a radiator rebuild w/ an all new copper core and clean up the end tanks/reassemble the rad. That's no issue and parts are coming in for the surgery.

Now that the rad is apart--i can look further into a second issue--the engine oil cooler. My engine oil cooler is not hooked up--this is how i received the car from the previous owner. the lines are capped off at the engine. what was-- if any-- common fail point of the engine oil cooler setup? My initial thought was one of the threads were stripped on the cooler or it physically leaks. Yet the cooler has pressure checked out and threads are nice. Maybe i have a rare instance of 1 line went bad, so both were blocked off until a later fix that never materialized. yet that seems to good to be true. Sorry im not to familiar w/ the fail issues of these cars. As the car is 8 years older than I.

thanks for insight

mike

There was never any particular problem with oil cooler setup. Once every 20 years you replace hoses.

thank you for the reply back. just the info I needed pertaining the failure--if any. so good chance mine may have failed via normal wear and tear and simply never replaced.

i can get both lines through imc or worldpac w/ ease.

One more question for you-- the illustration you posted w/ part numbers. How do i obtain the software to look up numbers myself? I have similar programs for vw/audi/porsche/bmw. Yet nothing for mb. I think that would be beneficial for me to have.

Thanks

Mike
