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.
