just can't thank everyone enough for your advice and effort. here's more.info:

1) the temp rises very rapidly, certainly within the 10 minute range, driving or in the garage at idle (but with blipped throttle.)

2) t-stat must be opening , as evidenced by the very high temp on the other side (the neck of the overflow tank). I could be wrong, but I don't think that's "where the money is". (Sutton's Law)

3) I've never tested the system w/o the thermostat, and I might, but I just don't think that's it. (see #2 + my stubborn personality)

4) I'm running bone stock everything, including pulleys.

5) Can I run the lower hose into a big tub of water with the t-stat in, and get an accurate determination about function the WP?

6) Note to Thomas Kirkham: thanx for your help (again!). I can't see how this has anything to do with your really excellent work, but appreciate your wilingness, as always, (and everyone else's) to pitch in and help me solve this conundrum.

7) What are the chances that this is an air pocket problem, despite the fact that, with the car level, no air came from the coolant temp sensor outlet in the intake?

8) What are the chances that it is a bad, tho' brand new, water pump?
