just a curiosity issue here. i = always assumed that turning on the heater would help an about to overheat = engine cool down. the idea being that coolant will be further cooled down by = being passed thru the heater core. well, i also had this other = thought, that maybe possibly, there is some counter effect by the extra stress = caused to the engine by the electrical needs of the heater blower, ie the engine has = to work harder to run the electrical motor, and thus get a little = hotter. my intuition says that the cooling effect will probably = outweight the heating effect. any other opinions on this?
