Thanks Blue Dragon.

Seems there's a consensus that the electric water pump is a weak link, so i figure spend the $500 or so on it and replace while I'm in there with the thermostat replacement.

Tend to think the same about the radiator.

Summer is coming. Get it done now.

AGREED, (Although this is from my E39, i think i can help a bit) when my thermo was just replaced, it got stuck closed a few times, but then never happened again. (no coolant loss either) Keep in mind it was a new part, I wouldn't let something like this go unchecked with an aged one.

I had almost the same symptoms you are going through.
