What is the fan located behind the radiator?
Those located at the rear of the radiator are called puller fans. The pusher fans receive air that comes in through the grill area and then they push that cooler air over the radiator. The puller fans pull the air from the grill, drawing it over the radiator.
How do I know if my radiator fan motor is bad?
Symptoms of a Bad or Failing Cooling/Radiator Fan Motor
- 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. Another symptom of a possible problem with the cooling or radiator fan motors is the vehicle overheating.
- Blown fuse.
What causes radiator fan to stop working?
Six things may prevent an electric cooling fan from coming on: Defective temperature switch, coolant sensor or other sensor. Engine thermostat is stuck OPEN (engine never gets hot enough to turn on the fan) Faulty fan relay.
What controls the radiator fan?
A mechanical fan is connected to the engine directly by drive pulleys. This type of radiator fan is controlled by a thermal fan clutch that senses radiator heat. After sensing the heat temperature, the radiator fan turns on when the engine is running at a higher temperature.
What are the signs of a bad thermostat?
Symptoms of a Failing Car Thermostat
- The temperature gauge reads high and the engine overheats.
- The temperature changes erratically.
- The vehicle’s coolant leaks around the thermostat or under the vehicle.
How much does it cost to fix radiator fan?
The average cost for radiator fan motor replacement is between $593 and $627. Labor costs are estimated between $128 and $162 while parts are priced at $465. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.
How much does it cost to replace a radiator fan motor?
Can I replace my own radiator fan?
Without the cooling fan, very little air is drawn through the radiator allowing the exchange of heat within the coolant. The cooling/radiator fan assembly must be removed in order to change the motor. Below we will cover the process necessary to complete the change of the cooling/radiator fan motor, for most cars.
Is there a fuse for the radiator fan?
The cooling fan relay is normally located in either the underhood fuse and relay center or mounted to the electric fan assembly behind the radiator. Keep area around the fan blade clear in order to avoid injury.
Can a bad thermostat cause radiator fan not to work?
If the thermostat is stuck open (allowing coolant to flow) it can cause the engine to run cooler than normal so obviously the fan wouldn’t come on..but not like the engine/coolant can be running too hot and the thermostat somehow effects the sensor reading or operation of the fan.
How do you replace a radiator cooling fan?
Begin with the engine cold, vehicle on level ground in park, with the emergency brake set. Step 1 – Locate and disconnect the electrical connector for the cooling fan. Step 2 – Next, remove the lower mounting bolts that attach the fan to the radiator. (Note: Some vehicles have alignment dowels which need not be removed.)
Where is the electric fan on a radiator?
An electric fan motor connected to a plastic fan blade located directly behind the radiator which is controlled by a coolant temperature sensor. This engine temperature information is utilized by the computer which signals the control relay to send power to the cooling fan.
How do you replace a cooling fan relay?
The cooling fan relay has an electrical connector that will need to be disconnected and switched over to the replacement cooling fan relay. Most commonly used connectors are a push type connector. Disconnect connector and remove cooling fan relay. Step 3: Compare the replacement cooling fan relay to the one being removed.
Why does my car have a radiator fan?
You probably already know the purpose of the radiator and the cooling system in your car. When you are driving fast, the wind is passing through the radiator to cool the coolant down without issues, but when you are driving slow, there is no wind pushed through the radiator. This is why we use a radiator fan.
