Yea the radiator fans r coming on . But the motor has been running about 215 and it usually runs around 180 ish. No water leaks I think that is thermostat. Would that make it no blow cold . I have also changed the flap that changes the air over . But I don't if the thermostat wouldmake it not blow cold or make all the lines under the hood r really hot. Meaning a/c lines.
