Well I'm lost on Mikep's 195 theory. If you say that the guage is calibrated to a 195 degree thermostat, then you put in a 180 degree then the guage will not read the temp correctly, as in it will read too low, well if that is the case then I guess that my motor stays overheated while running, because my guage reads a little less than halfway between the last mark off cold and the mark on hot, So I guess that the 180 degree thermostat is causing the motor to run hotter than a 195 degree or no thermostat at all? Strange theory especially with a new water pump, new radiator, new hoses, new thermostat, and an aluminum intake. So what is the problem?
