How does an electric radiator fan in a car work?
Electric radiator-fan motors are switched on either by the ignition switch – and run while the engine is working – or by a thermostatic switch . Thermostatically controlled motors do not work the fan until the engine coolant rises above normal operating temperature, and then switch off when it has cooled down again.
What happens when the radiator fan does not turn on?
The fan is responsible for keeping the coolant at the right temperature. If the fan is failing, engine temperatures will begin to rise. While the fan should turn on as soon as the temperature reaches a certain point, it won’t. Many times, drivers aren’t aware that the engine is overheating until the temperature light goes on the dashboard.
Where is the cooling fan located on a late model car?
The radiator cooling fan is mounted directly to the radiator. All late model vehicles are equipped with a radiator cooling fan. In some vehicles, there is more than one radiator cooling fan attached to the radiator. It’s possible to have one fail while the other continues operation.
Which is the correct direction for the radiator fan to blow?
If the radiator is mounted on the side of the vehicle, the fan should pull air in. The reasoning is that pulling outside air inwards will mean that cooler air will flow through the fins on the radiator instead of pushing hot air from around the hot engine through the radiator.
Are there any electric radiator fans for high performance cars?
Of course, high-performance engines require more airflow. Many electric cooling fans are rated by recommended horsepower to help you choose the optimum cooling fan for your vehicle. Electric radiator fans are available in both pusher and puller designs. Pusher-style fans mount on the front of the radiator and blow air through the radiator core.
Do you need a fan behind or in front of the radiator?
Some folks believe more fans are better. But that isn’t completely true, either. You don’t really need a fan both behind and in front of the radiator. Ideally, you will have a fan behind the radiator that provides cooling capacity based on coolant temperature.
Do you have an electric cooling fan in your car?
If the cooling system in your vehicle uses an electric cooling fan, most likely you have a transversal (sideways) mounted engine. However, some longitudinal (front to rear) mounted engines use the electric fan as well, but they usually have an engine-powered cooling fan.
Why does the radiator cooling fan stay on high speed?
When I drive, the cooling fan comes on turbo mode and truck is not running hot. The fan stays on high and will not go off until truck is turned off. Heat inside the car is hot and truck does not overheat. Coolant level is perfect. helpful? So I assume this did not do this before you made this repair of the water pump?
