How To Test Radiator Fan With Multimeter
The main function of a radiator fan is to prevent the engine from overheating. It distributes cooler air through the engine’s radiator and heat exchanger. This fan, which has four to eight blades, rotates rapidly to deliver cooler air to the motor. It acts as part of the overall cooling system. If the fan has any problems or stops working, you can use a multimeter to check that it has the correct voltage and that its motors are working. Do you know how to check the radiator fan with a multimeter? There is a sensor on the lower passenger side of the radiator. It does the job of recording the coolant temperature. It sends a signal to the radiator fan to turn on when the temperature crosses 172°F. The fan should also turn on after turning on the air conditioner. There must be a problem with the fan if it doesn’t spin when it should and spin when it shouldn’t. In either case you can detect the problem using a multimeter.

How to check the Radiator Fan with a Multimeter
If the radiator fan is not running, you must check its fuses to find out if the problem is with the fan itself or other components in the system. So how to check the radiator fan, this is how to check the radiator fan with a multimeter by checking the fuse.

- Fuse blown? Here’s how to fix the problem.
Check the fuse with a multimeter
So, to know how to check if the radiator fan is working or not, you have to check the voltage of a few fuses in the fuse box under the dash (numbers 3, 15 and 20) and the fuse box under the hood ( numbers 47 and 50. ). Start the engine or turn the ignition off to IG2. Set the multimeter to ’20’ in the DCV section because you will be testing a 12V circuit. The black multimeter probe will go to the negative battery terminal (for the fuse under the hood) or the metal ground point on the car (for the- dash fuse). Each fuse has two contacts that you must touch the multimeter’s test probes to get a reading.

There’s no need to worry about recording an exact voltage reading as it varies due to a number of factors including alternator output and charge in the battery. Tap the cloak for another contact and read. Now, what do the readings mean? How to test the cooling fan with this tool? 12V on both contacts. It means the fuse is working fine and you just need to move on to check the next one.Read more: how to check if windows 8.1 is genuine or not | Q&A12V on one contact and 0V on the other. This is a sign of a blown fuse. You need to replace it.0V on both contacts. It means the fuse does not have any power, this is only possible if the black probe is not properly connected to the negative terminal of the battery or ground to the metal part. Remove the probe and then reconnect it to take readings.
Frequently asked questions
Since radiator fans are such an essential part of a car, our automotive experts have all the questions answered around this:1. How to know if the radiator fan is broken?Usually, a bad cooling fan is easy to spot. Here are the 3 most common symptoms:Fuse blownFirst of all, a blown radiator fan is the most well known symptom. Car owners understand the importance of a cooling fan motor because it keeps the car at the right temperature, especially when idling and at low speeds. So, if this component were to supercharge, the fuse would blow for the benefit of the motor: The voltage would damage the entire system if the fuse switched them all the way into the system. The simple method to fix this problem is to replace the fuse to restore fan functionality.Car overheatingSecond, an overheating car is another sign of a radiator fan problem. Radiator fans are created for the purpose of cooling and conditioning the air when it reaches a certain temperature. However, when the cooling fan motor fails, the temperature will continue to rise, resulting in the motor overheating. On the other hand, vehicle overheating can be caused by many different factors, so you should diagnose your vehicle thoroughly.Cooling fan stopped workingLast but not least, a bad cooling fan is a cooling fan that stops working. This could be due to an engine failure that shuts down the cooling fan, thus making it impossible for air to escape.2. Should the radiator fan be turned on when the car starts?The temperature of the engine is the main factor to activate the radiator fan. Below 200 degrees, the fan is off, above it, the fan is on.3. What causes the radiator fan to be noisy?There are many factors that can trigger the fan: Coolant temperature sensor, temperature switch, etc.4. Is the cooling fan AC powered on?There are two common factors that open a radiator fan: When the AC compressor is running and when the coolant sensor reaches the appropriate temperature.5. What controls the radiator fan?The radiator fan clutch is the part that controls the radiator fan. This unit can sense the heat of the radiator to activate or deactivate the cooling fan. For that reason, when the engine reaches a higher than standard temperature, the radiator fan is turned on.6. How much does it cost to repair the radiator fan?The cost of a radiator fan is not as expensive as many drivers think: Around 300-450 USD is the price that most car manufacturers and auto shops have. With that, car owners could expect to pay $200 for the labor involved.
