What fuse controls my radiator fan?

By Olivia Owen |

What fuse controls my 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 do I know if my radiator fan fuse is bad?

Symptoms of a Bad or Failing Cooling/Radiator Fan Motor

  1. Cooling fans do not come on. The most common symptom of a faulty cooling fan motor are cooling fans that do not come on.
  2. Vehicle overheating. Another symptom of a possible problem with the cooling or radiator fan motors is the vehicle overheating.
  3. Blown fuse.

Does a radiator fan have a fuse?

A radiator fan is necessary to keep your car cool. The fuses inside of the radiator fan must be in good working order to make sure that the engine is able to stay cool. Without these components your car overheats.

What relay controls the radiator fan?

cooling fan relay
The cooling fan relay is the relay that controls the engine’s cooling fans. When the correct parameters are met, a temperature switch or the computer will activate the relay, which will allow power to the fans.

When should my radiator fan 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 does the radiator cooling fan relay work?

The cooling fan relay takes the low voltage signal and internally switches the relay “on” to allow battery voltage to be supplied to the radiator cooling fan. By using a lower voltage signal to control the relay, there is less stress on the rest of the wiring and charging system.

What do you need to know about radiator fan control?

The simplest form of radiator fan control is a switch that applies B+ voltage to the fan whenever the driver closes the switch, regardless of the ignition switch position. This arrangement is found on some race cars and custom vehicles. A disadvantage, of course, is that if the switch is left on, the battery will be discharged in a few hours.

Where does the cooling fan in the engine go?

The cooling fan in the engine compartment should turn on to pull air through the radiator and A/C condenser. A main cooling fan for the radiator. A second fan for the condenser.

How do you remove a radiator fan motor?

Step 1 – Make a note of the parts that need to be removed from your car. Look at the engine compartment area and identify anything that is in the way of your clear path to the radiator fan motor. You may need to remove some bolts, screws, and clips.

Can a radiator fan and condenser fan share a relay?

There are, however, some models that use a dedicated second unit to the condenser. In such a scenario, the condenser fan and radiator fan may or may not share the same relay. If the cooling fan does not engage, you can check whether the relay is to blame by swapping it out for a different relay.

What are the symptoms of a bad cooling fan relay?

1. Engine running hot One of the first symptoms commonly associated with a bad or failing cooling fan relay is an engine that runs hot or overheats. If you notice that your engine is running at higher temperatures than normal, that may be a sign that the relay is not functioning properly.
