To check the temperature at which the fan comes on, turn the A/C off and keep the engine running until it reaches normal operating temperature. Most fans should come on when the coolant reaches about 200 to 230 degrees. If the fan does not come on, something in the control circuit is defective.
Keeping this in view, what temp should car fan kick in?
about 200 degrees Fahrenheit
Beside above, should cooling fan come on when AC is on? If the coolant level in the radiator is low, that can cause overheating inside the engine without the radiator fans running. Check that first, refill if necessary, burp air pockets from the cooling system. Both radiator fans should always run when the AC compressor is engaged.
Accordingly, how do I know if my cooling fan is bad?
Usually a bad or failing cooling fan motor will display a few symptoms that can alert the driver of a potential problem that should be serviced.
- Cooling fans do not come on. The most common symptom of a faulty cooling fan motor are cooling fans that do not come on.
- Vehicle overheating.
- Blown fuse.
How long does a radiator fan take to turn on?
15-20 minutes
