The fan only really needs to be on when your idleing. That is what draws air through the vanes on the radiator. 120 degrees is not overheating. Given your using your cars gauge to get that reading. Check your temp sensor and there should be a fan relay and or a fan control moudule for your radiator fan. It tells when to cut the fan on and off. If you want there is an after market fan control at local auto parts you can install to control the fan.

92 Honda accord. Radiator cooling fan does not turn on. All fuses were checked...Ok, Replaced both A and B temperature switches. The A switch, located at the thermostat housing was tested by putting it...


If bypassing the sensor in the car allows the fan to start, then I would say the issue has to do with the sensor. I've heard of them getting an air pocket around the sensor and preventing the fan from coming on. Maybe the contacts aren't making up in the connector? Corrosion could be causing an issue. Maybe a loose wire that opens the circuit when plugged into the sensor.

Car running hot


Check fan relay and wire connections; if they are ok, and the fan work if you jump directly, could be the temperature sending unit, engine temperature sensor out of range or thermostat stuck. Stop the car, could overheating and damage other components and engine itself.

Overheats if left idling but not if driving...cooling fans aren't coming on...what couls be wrong?


the cooling fans on your car are comanded on by the engine control module which reads engine temperature from the temperature sensor . when comanded on the engine control module sends a signal to the cooling fan relays . which in turn runs the current to the cooling fans . So you might want to check the cooling fan relays and make sure the fues for the cooling fans are good and the relays .if the cooling fan fuses and relays are good it could be a problem with the fan motors or the engine control module not reading the right temperature in that case it could mean you have a problem with the temperature sensor

+my honda civic 1998 radiator cooling fan not turning.


This gets complicated. First of all don't let the engine
overheat. There are two complete fan circuits, one for
the air conditioning and one for the radiator. To test
the fan, remove the electrical connector at the fan and
use jumper wires to connect the fan motor directly to
the battery. If it doesn't run, replace it, if it does operate
try the fuses located in the engine compartment or
under the driver's side dash. The fuse diagram should
be on the fuse box cover. Other than that you may need
professional help.

Would my cooling fan fuse be bad if the car is starting to overheat


Hi. If the cooling fan is not working or i should say if it will not go automatic if the car reached the threshold temperature then thre could be problem on the fuse or to the relay of the fan. You can test the fan by connecting the positive and the negative wire directly to the battery and see if it will run if directly connected.

Radiator fan doesn' run


If you can apply 12volts directly to the fan connection and it runs, then the fan thermostat is your problem. If a direct connection does not work, then the fan motor has failed and will need to be replaced.

Cooling fan is not working


If you have not checked it yet, you can do so, around the lower right corner of the fan motor is the electrical connection. Us 2 jumper wires and connect directly to the hot and neg post of the battery, if the fan does not work, replace the fan motor. do this for both sides, this should give you which direction you will need to go. If the motor is good, check the fuses (the one in the engine compartment). the coolant temperature switch, the radiator relay, and lastly the condenser fan relay. I hope this helps you, Good Luck!

Engine over heating.


deep copper color is only rust. you can remove that by back flowing the empty system. There exist some cleaning fluids to let it run for a while as well. Go to autoshop.
Check fan by connecting direct to power if ok, suspect temperature sensing switch on the block.
The old thermostats can cause boiling over, they need replacement once in a while. You can check this with a oven thermometer old style in a opan of water on your stove reading the watched opening temperature. Replace with right value. They come in sorts some times.
