Periodic Overheating Not Solved Again

Not really.

Being you didn't make any effort to give the year, model and engine size, I really doubt anyone could give an educated guess.

I believe it's still his early nineties 3.0 AeroScare.

A water pump is a water pump

Try to install a small block chevy pump on that AeroScare - - - - ANd I've seen the (plastic) impellers on some fords totally "explode" at about 4000 engine RPM (2.5 duratec) and I.ve seen water pump impellers "slip" on the shaft when hot (Chrysler slant six) including one of each on my own vehicles - as well as on numerous customer vehicles.

That's my thought, too. Coolant is not circulating, so to me that means either the pump is failing or something is blocking the flow. Thermostat opens at the right temp.

I reckon I can't complain about getting 21 years and 150K miles (8000 Canadian) out of the pump.

I'll say one thing about Ford, original parts are head and shoulders above any other car I've had. Original radiator went 17 years.

Only bad parts I have seen are the AC compressor and everything in the heater circuit.

Of course the most important part - radio/cassette - works like new.

Back to the cooling again. Any simple way to tell if the water pump is going bad in thus aeroscare before giving it over to mr monkeywrench?

Part 2... Obd2 says vacuum leak on side 1. I checked all connections and hoses i can see. Whats next ti check?

Check your local scrapyard for vacancies.

As a former Aeroscare owner (2 of them) - and I REALLY liked them both

- there comes a time to let a dead horse lie down. Mine both went past 240,000km before that time came - and were no longer in my care when that happened.

Yep, im thinking i got my money out of it. Heater, ac bad now. PS never stopped squealing after new one installed. upholstry non existant after converted to hauling lumber. Worst if all, the cigarette lighter failed. Lol.

Even all that i can live with. The difficult access to plugs and most engine parts i wont miss.
