Can I Drive My Car Without Radiator Fan? 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.
Can you drive with a broken radiator fan blade? Do not drive with broken fan blades. Close, but not quite. The motor mounts being bad allows the engine to move too much when accelerating and decelerating.
What happens if your radiator fan stops working? If your cooling fan stops working, your engine could overheat. This could cause damage to your engine parts. It’s a serious issue and needs to be looked at by a garage.
How important is the radiator fan? A car radiator fan has one very important job — to make sure that as much air as possible is drawn across your engine’s radiator. This helps to ensure that your motor is able to maintain a safe and stable temperature no matter how fast you’re driving or how hot external temperatures get.

Are radiator fans needed?
Air cools the radiator and the coolant in it before it sends it back into the engine to pick up some more heat. Now your engine has an ideal temperature range in which it is most efficient: it shouldn’t be too hot or too cool. The electric radiator fans help maintain the ideal temperature.
How much does it cost to replace an engine 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 long does a radiator fan take to turn 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 there’s a problem with the engine’s temperature, then this can damage the radiator.
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 much does it cost to fix radiator fan?
The average cost for a replacement fan is between $634 and $789. Labor costs are between $102 and $130 while parts are between $532 and $659. Taxes and fees are not included in the estimate.
How do I know if I need a new radiator fan?
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.
Why is my radiator fan so loud?
Worn bearings, bent or broken blades, and unbalanced rotating assemblies can cause a fan to screech, howl, or otherwise make noises it shouldn’t. If you have a noisy radiator fan, don’t put up with it any longer than you have to. Our expert mechanics are here to help with all your vehicle service needs.
Should radiator fan turn on when AC is on?
Both radiator fans should always run when the AC compressor is engaged. 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.
Are Case fans and radiator fans the same?
There are two main stats for a fan. There’s the CFM (cubic feet per minute) rating, which describes how good it is at moving air when there isn’t any obstruction. On a radiator, you need high static pressure, and for case fans, you want high CFM.
Is a radiator fan the same as a cooling fan?
There’s no difference, really; both remove waste heat generated by the engine’s combustion process. A radiator is used in water-cooled engines and the fan removes heat from the cooling fluid in the radiator before it returns to the engine.
Which fuse is 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.
At what temperature does a radiator fan turn on?
A temperature-sensitive switch functions to turn the fan on and off periodically. Radiator fans are designed to start when the temperature of the engine coolant reaches around 200 degrees Fahrenheit.
How do I know if my radiator fan is bad?
The first symptom or sign that something has gone wrong is that your cooling fan doesn’t come on at all. This is the most common symptom of a faulty cooling fan motor, but it may not be one you notice while driving your vehicle. If the motor burned out or starts to fail in any way, the cooling fans are disabled.
How do you test a radiator fan?
How to Check a Radiator Fan
Determine whether your radiator fan is manual or electric.
To check an electric radiator fan, start the car and let it get up to the temperature where the fan normally kicks on.
Use the volt meter to test if there is power to the wires.
Normal voltage for a radiator fan is around 12 volts.
What are the symptoms of a bad thermostat?
Leakage from the mounting surface. Appearance: Seepage, drips or large coolant bleed marks on or around the mounting surface or on the housing.
Rust and corrosion. Appearance: Rust and corrosion on the surfaces of the thermostat.
Deposit build-up.
Map-controlled thermostats.
What causes a radiator fan to not turn on?
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.
Do both radiator fans turn on at the same time?
The answer to your question is yes both fans will run when your at 230 degrees, if you have the parking lights on and your at 212 degrees one fan will come on, and when you have the air conditioning on you have one fan on as well.
