Chevrolet Cobalt Forum : “MY FAN DOESN'T COME ON EVEN WHEN MY COOLANT TEMPERATURE REACHES 220 DEGREES. WHA...”
MY FAN DOESN'T COME ON EVEN WHEN MY COOLANT TEMPERATURE REACHES 220 DEGREES. WHAT IS A NORMAL, SAFE COOLANT TEMP. RANGE FOR THIS CAR?
THE COOLANT TEMPERATURE HAS BEEN GETTING AS HIGH AS 228 DEGREES, AFTER THE CAR HAS BEEN RUNNING FOR AT LEAST 15 MINUTES. IT DOESN'T START OUT HIGH, BUT I DON'T KNOW THE NORMAL RANGE FOR THE COOLANT TEMPERATURE. MY FAN IS NOT COMING ON, EVEN AT 228 DEGREES.
THE CAR WAS BOUGHT USED, BUT IS STILL UNDER DEALER'S WARRANTY. SHOULD I HAVE IT CHECKED, OR IS IT OK FOR THE TEMP. TO BE THAT HIGH AND NO FAN KICK ON?
Have it checked. Sounds like either the fan relay or fan control is not operational. Typically there is a high and low speed fan operation, the low usually kicks on around 185, high around 212. Shouldn't get to 230 with no fan at all. Then again your coolant temp sensor may be bad, but even so the fan should kick on.
HI all can any one help please ?????
i have the same problem with my optra LS 2006 and when i run the air conditionar both fans operate ..
i tried to remove the temperature sensor wires the low fan does not work ..
what should i do ??? should i change the sensor
by the way i have 5 volts on the wire terminals
have da fan relay and da thermostat checked out its more than likely those to that are causing it to overheat, and if it was me i would stop driving da car
