Does radiator fan turn on immediately?
Turn the air conditioning to the maximum setting – this should spark the cooling fan to immediately come on. This typically takes about 15-20 minutes for the engine to reach the right temperature for the radiator fan to turn on in older cars. If the fan doesn’t come on, you need to look for a broken fuse or breaker.
Is it possible for an electric cooling fan to run if the ignition is turned off?

When does the cooling fan turn on on a Toyota?
The Toyota’s fan only turns on when the coolant reaches a certain temperature, which is measured by a sensor. This sensor switches the cooling fan off and on as needed.
How is the coolant temperature of a Toyota regulated?
A Toyota’s coolant temperature is regulated by many electrical and mechanical components. One of the more important components is the cooling fan. The fan lowers the coolant temperature after the coolant has finished its cycle through the engine. A Toyota’s cooling fan is powered by an electric motor.
Why does the cooling fan not turn on?
As the motor ages, the circuitry can fail, causing the motor to malfunction. This leads to the fan not operating properly or not at all. The Toyota’s fan only turns on when the coolant reaches a certain temperature, which is measured by a sensor. This sensor switches the cooling fan off and on as needed.
What to do if your Toyota won’t start?
Battery – If the connections on your battery become corroded, there is no longer a connection to the rest of the car. This can keep you from starting. Clean the posts and try to start the car. Additionally, the battery may be dead. Take a battery tester and test the cranking amps to see if they are weak.
