Has there been an STC or field approval on an oil cooler for a 172A?

You could contact a cooler manufacturer to find out.

Or the FAA website has the STC's and you can search.

YES!!Has there been an STC or field approval on an oil cooler for a 172A?
Probably; I know of a flight school in Columbia, CA that has an old straight tail with a cooler mounted on the firewall behind a Cont O-300. I'm just guessing that its probably STC'd.
