Then, how do I know if my radiator fan is bad?

Symptoms of a Bad Radiator Fan

  1. No Whirring Noise from the Engine Bay. The radiator fan makes a noticeable sound when it operates.
  2. Rising Temperature Gauge. When the radiator fan stops working, the coolant does not cool down.
  3. Coolant Evaporates.
  4. The Radiator Fan Relay.
  5. The Radiator Fan Motor.
  6. The Radiator Fan Resistor.

Also Know, how long should a radiator fan last? Image Gallery: Car Safety Most auto mechanics agree that a properly maintained radiator should last for at least eight to 10 years. See more car safety pictures. An automobile engine wastes a lot of energy in the form of heat.

Also Know, what causes radiator fan to stop working?

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. A wiring problem (blown fuse, loose or corroded connector, shorts, opens, etc.)

Can you drive 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.

Should radiator fan run 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.

How do you test a radiator fan?

How to Check a Radiator Fan
  1. Determine whether your radiator fan is manual or electric.
  2. To check an electric radiator fan, start the car and let it get up to the temperature where the fan normally kicks on.
  3. Use the volt meter to test if there is power to the wires.
  4. Normal voltage for a radiator fan is around 12 volts.

When should you replace a radiator fan?

Another way is to watch the temperature gauge, and if it constantly reads high, it may be time to have your cooling/radiator fan motor replaced. To keep this part in good working condition, the coolant should be changed every 25,000 to 40,000 miles.

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.

How much is a cooling fan relay?

To get your cooling fan relay replaced, you will pay, on average, $80-$160, depending on the type of car you have and the mechanic's fees. The labor should cost around $70, while parts should run you $10-$50.

Where is the cooling fan sensor?

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.

Where is the cooling fan switch located?

Locate the cooling fan switch near the thermostat housing on the left side of engine behind the distributor assembly.

How do I know when my water pump is bad?

Here are some common symptoms that hint towards having a bad water pump:
  1. Coolant leak at the front-center of your car.
  2. Water pump pulley is loose and making whining sounds.
  3. Engine is overheating.
  4. Steam coming from your radiator.

How do you direct a radiator fan?

How to Straight Wire a Cooling Fan to an Engine
  1. Locate the positive and negative wires on the cooling fan. Cut both wires and strip 1/2 an inch of insulation off of the ends of the two fan wires.
  2. Connect one end of the 12-gauge jumper wire to the black ground wire of the fan. Connect the other end of that wire to the engine block or any metal part of the car body.

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.

Does the coolant temp sensor control the fan?

The sensor works by measuring the temperature that's being given off by the thermostat and/or the coolant itself. The temperature is then sent to the on-board control system. As the control system receives the temperature from the CTS, it may trigger the cooling fan to either shut off or turn on.

Does the radiator fan run all the time?

An electric fan SHOULD NOT run all the time. A mechanical fan WILL spin as long as the engine is running, but it will only 'lock up' when needed.

How do you replace a cooling fan?

  1. Step 1: Locate the Radiator Cooling Fan. Locating the radiator cooling fan is the first step in replacing it.
  2. Step 2: Disconnect the Power Supply.
  3. Step 3: Remove the Fan Housing.
  4. Step 4: Remove the Radiator Cooling Fan and the Fan Motor.
  5. Step 5: Attach the Replacement Radiator Cooling Fan and Fan Motor.

How much does it cost to replace a cooling fan?

The average cost for cooling fan replacement is $240 to $610 depending on the make, model, and style of cooling fan used.

Will a bad radiator fan cause AC not to work?

Yes, a broken radiator fan can cause the air conditiong to stop working. The AC system depends upon being able to dissipate heat into the engine coolant. You really need to have the fan replaced, or at least, have a diagnostic check to see what is causing the fan to stop working.

Do radiator fans always spin?

This unit spins when the engine is running, and it always spins at the same rate as the engine. The faster the engine is running the faster the fan will spin. If you find that your vehicle is not cooling off properly, the radiator fan might be the culprit. You can replace the fan with a new unit.
