I was going to mention this before, if I didn't already, a sort of quick
and dirty check on the pump, or at least coolant flow.
If you rev the engine up manually (under the hood), you should see a
fair amount of turbulence in the overflow tank as it gets circulated.
The engine might need to be warm (thermostat open) for this to work, I
Also, during warm up, as the tstat opens, you should be able to feel the
warm coolant move through the radiator. Not very convincing of flow,
but it is something.
I also forget (had one of these years ago), does the transmission have
cooling lines running through the radiator? if so, that may be a source
of extra heat. Though, the radiator should be able to cast it off.
Do you still have A/C?
