When do you turn on the radiator fan?
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. Click to see full answer.
Why do you need a radiator fan in a car?
The radiator fan is a crucial part of your car that is in charge of cooling the car and keeping the occupants at a normal temperature level. These cooling radiator fans are very imperative to when your car is running slowly or sitting still, as external airflow will not be able to move through the grille and cool-off the passengers.
Is the fan supposed to be on when AC is on?
Both radiator fans should always run when the AC compressor is engaged. Both radiator fans should always run when the coolant temperature sensor in the bottom tank of the radiator reaches about 212*F. Click to see full answer. Similarly one may ask, is the fan supposed to be on when AC is on?
What happens when the radiator fan burns out?
If the cooling fan motor burns out, the cooling fans will then, in turn, be disabled. Since the cooling fan motors work in tandem with the fan blades to pull air through the radiator, the blades will then not be able to spin or cause any airflow to cool off the car.

Why does a car have a radiator fan?
The primary cooling for an engine, besides coolant, which simply raises the boiling point of the water, is a result of the water being cooled by circulating it through the channels of the radiator. The thin fins of the radiator help to dissipate the heat as fresh, cooler air is pulled through the radiator from the front of the vehicle.

Why does my radiator not turn on when I start the car?
However, if you are able to notice the telltale signs and symptoms of a bad or failing radiator fan motor, you might be able to stop the problem before it gets worse. The most common symptom of a faulty cooling radiator fan motor is that the cooling fan does not come on when you start the car.
Both radiator fans should always run when the coolant temperature sensor in the bottom tank of the radiator reaches about 212*F. Click to see full answer. Similarly one may ask, is the fan supposed to be on when AC is on? The fan only turns on when cooling or heating (in winter) is required.
Can a radiator fan and condenser fan share a relay?
There are, however, some models that use a dedicated second unit to the condenser. In such a scenario, the condenser fan and radiator fan may or may not share the same relay. If the cooling fan does not engage, you can check whether the relay is to blame by swapping it out for a different relay.
What happens when a radiator relay goes bad?
A faulty or broken relay cannot deliver power to the cooling fans. In turn, the unpowered fans won’t run, leaving the radiator to its own devices. Deprived of the helpful influx of air from the cooling fans, the radiator cannot remove as much heat as it usually does.
How does a secondary radiator cool an engine?
The first, more conventional system cools the engine by sending coolant through passages in the block and to a heat exchanger up front, and also directs coolant to an oil cooler and the heater core.
