So where exactly is the temp gauge supposed to read at for normal operating temp? The temperature will get to the M and kick back down below R (after fan finished running). When I first acquired the car I don't remember it running this hot, It never over heats or even gets close to the red area but I don’t want to stress the engine out anymore than I already have. New original temperature thermostat, new coolant switch and sensor plus replaced the radiator with one that was out of a Thunderbird. Only thing left to do is maybe try another thermostat or new water pump. I did run some crappy water through it not too long ago, is it possible that the water could have deteriorated some stuff, heater core?
