I am surprised that nobody has pointed out that one of the side effects of
those nifty sealing powders is the occasional radiator blockage.

I had the same water pump impeller problem with a 1965 Plymouth. To the
original poster: Have you pulled the water pump and checked it?

Right on target there Scott....
"Bar's Stop-leak" is a known radiator destroyer

I didn't use a powder, I used this:

I called them beofre I even cracked the bottle with the same concern. The
woman who asnswered the phone said get ALL the antifreeze out. Flush it,
and drain it and flush it again. It has to be absolutely clear water
coming out of the cooling system.

I used it with much success on another Subaru, but I guess this one must
be too far gone...

Nah...

On the '89 Suby it's a good old fashioned on-the-fan pump.

I think the '97 is at the timing belt, IIRC...

One thing I think people are missing: There *IS* exhaust gas in the
radiator. When I had it inspected the guy stuck the 'sniffer' in the
radiator filler neck and when we revved the engine hydrocarbons went way
up...
