Where are all the running hot posts?

Yeah, I've been leaning towards bearings in compressor going bad.

Worst possible case, etc.....

61,000 original miles. On almost everything.

When I had the engine out to replace the freeze plugs, I pressure washed the water jackets and picked out a handfull of rock like deposits, so it should be fairly free of cloggage in that area.

Water pump was replaced at that time.

If it ran borderline hot without AC, I'd suspect one of those other things, but it actually runs cooler than I'd think is normal otherwise.
