Running 'Warm'!

[Bernie Benz]

Good logic, Tom.

Further, the fan controlling thermostat is located in the cold, outflow side
of the radiator so coolant blockage by the thermostat or by Mike Miller's
suggestion of antifreeze slush are not logical explanations.  Audi gremlins?

Bernie,

This seems counter-intuitive to me.  If the the thermostat does not open, I
agree that it would certainly send the temp guage skyward, but how would
that account for the fan coming on at the high speed?  If the t-stat doesn't
open, coolant does not circulate through the radiator, so what tells the
radiator fan to come on full bore?  Isn't the switch in the (cold) rad
itself?  Or is it located somewhere else?

Tom

Could very well be a failing to open thermostat, BTDT at 175K. Mine didn't
owe me much more, but yours is infant morality!
