I drive a 1965 mercury comet with a Ford 127 HP online six. I replaced the radiator and the water pump, and put in a thermostat, but the thermosat is for racing and is rated for 180 F, my engine is supposed to have 160 F. Any given time I'm driving my car runs dangerously hot/overheats after about 1/2 and radiator fluid levels are normal, no leaks. Could the thermostat be the issue?
