Subject: Overheating at idle

My '86 recently began overheating but only at idle...drive all day on the
highway and it's fine, but stop and idle for a few minutes, and the
temperature climbs. Rev the engine and the temp returns to normal. Even
after a 15 minute drive: stop and idle, and it'll get hot.
I recently had a leak, so it might be an air lock problem ? I'm thinking the
water pump or the thermostat. It's not the fan since the radiator never
seems to get hot enough to kick that on. I guess tomorrow's job is pull the
thermostat and check it? There are no unusual noises from the water pump...
As usual, all advice and critiques appreciated  :)

Thanks
Tom
