I agree with nobody@[EMAIL PROTECTED]
and that these engines run better and more
efficiently warm (normal operating temp).
I have been told to match the thermostat with the proper temp fan switch.
AFAIK You want the thermostat and fans to work together not against each
other. Normally the thermostat opens up and then when the radiator gets
hot
enough the fans come on.
If the fan comes on too early, due to a lower temp fan switch, then the
coolant going back into the engine will be too cool and the thermostat
closes due to the engine becoming too cold. I see jumps of coolant
temperature readings.
You want a relatively stable temp. ;-)
So if you were going to boil water or add water to the boiling water,
would
you grab the water from the refrigerator or some stored at room
temperature?
You would burn a little more energy with the colder H20 from the fridge.
Easier on the system if the temps are close to one another! ;-)
At least that is how I see it! ;-)
Does this make sense?
