How do I know if my radiator fan motor is bad?
Signs of a Radiator Fan Assembly in Need of Replacement
- Engine Overheating. When the radiator fan isn’t functioning properly, it is not able to adequately cool down the car’s engine.
- Air Conditioner Function Diminished.
- Loud Noise Coming From Radiator Fan.
What causes a radiator fan to not come on?
The most common reasons why a radiator fan is not working are due to a blown fuse, a bad relay, or a broken wire. It can also be caused by a faulty coolant temp sensor, low coolant level or the fan itself can be damaged.
Where is the radiator fan located?
The car radiator fan is found between the engine and the radiator, although some radiator fans are found at the front or anterior part of the radiator. Electric fans are found in the front part of the radiator and are also referred to as “pusher fans”.
How much does it cost to replace a coolant fan?
As one of the more expensive car repairs needed (not including the replacement of a seized car engine, obviously), the replacement of the radiator coolant fan could incur about $128 to $162 in labor costs and around $465 in parts. So, total radiator fan replacement cost could be anywhere from $592 to $627.
Should radiator fan run when AC is on?
Q: Should the radiator fan run when AC is on? Yes. Both the radiator and condenser cooling fan are expected to turn on the moment you switch on the air conditioning system. For instance, it is expected for the cooling fan to switch on when the engine carries loads or once it reaches the normal operating temperature.
How do I check if my radiator fan is working?
The first part to check is the fan wiring when the fan isn’t working. Start by unplugging the positive and negative feed wires (should put out approximately 12 volts DC). Then, check to see if there’s current available with a voltmeter. If not, take a look at the wires and the fan relay under the car’s hood.
What sensor turns on the radiator fan?
coolant temperature sensor
On most modern cars, the cooling fan is controlled by the Engine Control Unit (ECU) which gets a signal from the coolant temperature sensor.
How do you test a radiator fan?

Can I drive car if radiator fan is not working?
Yes, you can drive your car without a radiator fan, but you never should. Your vehicle’s cooling system is crucial to its performance, and every time your engine overheats, you cause damage.

Is a cooling fan the same as a radiator fan?
The cooling fan is also known as a radiator fan because it’s mounted directly to the radiator in some engine layout. Typically, the fan is positioned between the radiator and engine as it draws heat to the atmosphere. In front-wheel cars, the cooling fan used is an electrical component powered by the battery.
When should radiator fans kick on?
about 200 degrees Fahrenheit
Your radiator fan should kick in at about 200 degrees Fahrenheit. If you notice your vehicle is overheating or at the very least running hotter than it normally does, listen for the fan to see if you can hear it.
How do I know if my radiator fan relay is bad?
Keep a lookout for the following bad cooling fan relay symptoms:
- The engine runs hot or overheats.
- The cooling fans don’t work.
- The cooling fans keep running.
- Warning lights.
- Poor air conditioning performance.
- Swapping Relays.
- Measuring the Relay Coil’s Resistance.
- Listening for Noises.
How can I tell if my radiator fan is working?
A simple way to check if the radiator fan is working is to start your engine and turn the air-conditioning system (A/C) to the maximum speed. If the fan is spinning, then it means that the fan motor, fuse, wiring, and relay are all working properly.
Is it hard to replace radiator fan?
Most cars have the radiator fan mounted directly on the radiator, making it simple to replace. If you are skilled with basic automotive tools and have some general expertise, you might be able to change the radiator fan yourself and save on the labor costs. However, you should never drive with a failing radiator fan.
