There is an ideal temperature range for any engine to operate within,
and the thermostat is designed to get the engine up to that point as
quickly as possible, and then keep in from climbing much higher. If the
thermostat is fully open, and the temp continues to rise, then the low
speed on the radiator fan is triggered. If temperature equilibrium is
(engine btu output versus cooling system heat rejection) is still not
achieved, the fan is triggered to run at high speed.
The idea that a cooler running engine is desirable is correct only as
long as you don't drop below the engine thermostat's setpoint. To run
it much below this can cause condensation in the oil, fuel mix problems,
etc.

You say that running cold "causes greater ring wear and a host of other
problems."
If this is indeed the case then this would be a good reason to NOT use
the
Red Line Water Wetter product to lower temperature. Anyone with Red
Line's
Water Wetter experience have any suggestions to the contrary?
Manufacturer
claims that the product can be used to provide rust and corrosion
protection
in plain water for racing engines. So would it provide similar
protection in
our systems with coolant?
The product label says it reduces temperature with a 50/50 coolant mix
by 8
degrees. Would running only 8 degrees lower cause the engine to run
rich?
And thus wash down the cylinder walls (of oil) causing greater ring wear
and
a host of other problems?
One earlier reply to my query was that the engine (well maintained) runs
perfectly well without "red line's water wetter" even while crossing the
desert using the AC and that adding Water Wetter is not necessary.
I always thought running cooler was a good thing, but then these VW
systems
are so new to me that I just am not convinced of anything yet.
Any informed advice anyone?
