Last week I changed my Mehran's radiator fan from direct to auto as my mechanic suggested so. It is 96 model. It was working well and fan used to start when temp gauge reached 60-70% and then stops at 50% until today I saw temperature gauge to its full right and radiator fan was starting and stopping as it used to do. But there was little steam from radiator as I suspect fan starts too late. What could have gone wrong? Today I change it back to direct
As I think sending unit, which is poor china one, is shorted to ground and hence gauge needle traveled to its far right. Is the thermostat dependent on the temperature sending unit or its independent?
