Hello, look on the radiator must carry a thermocoury, it is a ruptor that connects (current passes) when the temperature is more or less between 87 and 95 degrees and disconnects when it falls from that temperature (it does not pass current) is a round piece of plastic with a metal hexagon where the key is inserted to replace or put it new You find in the old cars were only two cables that when disconnected the two cables stopped the radiator and如果风扇工作的统一,但是今天,随着汽车携带很多汽车,可以看到散热器固定在哪里被卡住了,您将不得不平等地更换它。
