I've heard here in the forum that replacing a stock thermostat with a 180-degree unit (without modifying the fan circuit), will cause the engine to run hotter. Can someone please explain why? Why would a car run hotter if the 180-deg. thermostat opens sooner than a 195-deg? I would think that the car would run cooler, but the effect seems to be the total opposite. WHY?? :confused:

the coolant passes thru the radiator faster and does not have time to cool before returning to block. remove the thermostat and watch how fast and hot it gets. get a eec tuner to control the low and high speed fan with a 180 thermostat and you will have it made in the shade.
