radiator fan is supposed to turn on before over heating to draw more air thru radiator and over engine to assist with cooling if fan is not turning on soon enuff , you need a new lower temp fan switch
Ummmm, Radiator fans run off a temperature switch. Sometimes they put the fan switch and sender for the gauge together so I suppose it could be related. Have you checked to see if the wires are unplugged? Just a thought.
Check the coolant level. check the radiator fans.
Most likely you have overheating, that's why the keeps running. You need to check the temperature control sensor and the thermostat.
sounds like your temperature sensor unit if you have already checked the thermostat and the radiator and fans are ok
The fans normally come on when needed. Is the car running hot -- is the temperature gauge reading above normal? If so, there's a problem with the fans or the cooling system. If not, don't worry about it.
Inoperative radiator fans, bad water pump, failed headgasket?
a bad termastat
Why does the temperature gauge on your 2001 malibu not work and the cooling fans run all the time?
Low coolant? Water pump not circulating coolant? System air bound? cooling fans not working? Defective radiator cap? Bad temperature gauge?
likely possibilities are the following. Low or bad coolant , water pump, thermostat needs changing, clogged radiator or lines, coolant temperature sensor or radiator fans not coming on, head gasket Also check the radiator caps on the hose and the overflow container. That was my problem. One or both may have to be replaced.
If it has electric fans, make sure they are coming on when it get's hot. If not, then check the fuses and relays for them and power to the fans. Might just be a relay for the fans.
it may be your thermostat or water pump is it over heating with steam comming out ?
