Note to question/answer +question
The answer "the hot coolant is cooled by the fluid"
a good answer but thats not what I asked.
I believe that it is the primary purpose of the radiator to cool down the engine.
I must ask again: how to turn off if possible the heating of the
windshield fluid?Can I bypass the thermostat does the thermostat turn on when the temp.= freezing point?
Fumes of methanol are not very healthy since it is
a "wood alcohol"-if it is overheating the fluid so
that it cannot be drained to the windshield because it is
boiling than how do you fix this?
