<VV> Water temps - Air temps

[Sethracer at aol.com]

True, Jim. Just like the "fresh-air heater" Corvairs. If - (when?) you  
throw the fan belt, turn the heater on full blast right away!

The  heater in my Cruze can pull more heat out of the coolant than the 
engine  
dumps into it.  I have noticed that with the fan on the top one or  two 
speeds, the engine temperature will drop.  If you start with a  cold engine 
and kick the heater on, the engine never does really warm  up.  I've only 
tried this in cold weather.  Without the heater  running full tilt, the 
engine temperature behaves as expected, so the  thermostat is working.

If he was  talking about water temps, perhaps Mark meant: "The higher the
pressure in  the system, the higher the pressure CAN be."

Meaning - The higher  pressure will discourage boiling (also dependent on
coolant chemical  composition). You are correct, Jay. With stock water 
pumper
vehicles, I  have watched the water temps trend up under load - climbing the
grapevine -  then cool back down to thermostat temp while coasting
downhill. Some   of the characteristics change, depending on coolant fan 
design,
engine  driven  vs. electrics. Sitting in traffic, watching a temp gauge on 
 a
water pumper  with electric fans, can be a heart stopper! -  Seth

I disagree.
A higher pressure system CAN run at  a  higher temp without boiling.
Actual operating temperature depends  on  cooling system design and
vehicle operating conditions.
Running  down  the highway on a cool day, a water pumper is likely to  be
running at the  thermostat opening temperature.
In traffic on a  hot day, it will be running  all its fans and the coolant
temp will  probably be at or above the fan  thermostat temp.
