Let me throw my two cents in here:
1) I never had a problem with oil temps and my stock oil cooler. Never
higher than 195 on my digital monitor, except in a long climb from FL in
July. I think your oil temps may be symptomatic of something else...
2) PMA does NOT mean "same as factory", it merely means the FAA has approved
the production methods and materials to fabricate the parts as sumbitted.
PMA alone does not mean you can put the part on your plane unless it is
PMA'd as the exact replacement part per the original TC and drawings as I
understand the regs... As Gary has described, you can get PMA on a new
style cowling, but you still need the STC to mount it on a Grumman!
3) TC only applies to the aircraft as designed and submitted to the FAA, and
it's operating limitations. Notice that Cirrus is not re-accomplishing the
TC for the SR-22 with Turbo-normalizing, even though it will be a factory
option! The OEM figured it would be easier/faster/cheaper to licence Tornado
Alley's new STC - and they are probably right...
4) STC means someone has submitted the appropriate data to the FAA, and the
FAA accepted it for the specific application (so if Gary gets an STC for the
AA-5B, it won't apply to the AA-1...)
5) There are such things as one-time STCs, and Field Approved 337s that
muddy the waters even further!
I highly suggest you consult the regs for the final answers, I am just going
from the top of my head. Interestingly enough, the old, leaking oil cooler
I recently pulled off my 1975 Tiger was a 1973 vintage on my 1975, and was
OEM based upon my logbooks!

I am not an A&P and I sometimes get upset at the very officious replies to
simple questions so here is my input.
PMA means same as factory and you can install it with a log book entry.
maybe owner or maybe A&P... see part 43 (think Concord battery)
TC means that it is the factory part and can be installed with a log book
entry.
STC means that someone has done it before, the FAA has blessed it and you
can install it with a 337 and be guaranteed acceptance.
337 with no STC means that you hope the FAA will approve what you have
installed!
