Re: What is the best Thermostat temp?

	Sorry, I meant run cooler.  I guess the UR-Q tends to run a little
to hot and has a Heat Soak problem in the head.  John Karasaki put in a 70
deg C thermstat ( See his post).  I guess he is happy with it as I believe
it runs cooler now, which if was running TOO HOT could rob power so I
spose cooler could be running better.  Right.  At least more reliably.

	Jeesh, everyone keeps forgetting I want to replace it because it
is Stuck Open so I cant even get the gauge to read above the bottom on the
Freeway inn freezing temps.  Once in Town it starts to go up.  Anyhow I am
settling on an 87 - 95 degree unit I have decided.

	Agreed on the temp below the goosneck.  I spose you are right on
the flow direction thing.  L8R
