How To Install Radiator Fan Switch – Your radiator fan has stopped working, and while it’s not the end of the world, it would be more comfortable to drive the car with a working fan. Some causes of a broken fan also require immediate repair as they can lead to other problems if left untreated. Fortunately for you, the average cost of a radiator fan is not too expensive. The price is usually between $300-400. The mechanic may charge you an additional $100 to $200 for the work. However, in some cases, if you wait too long, the cost can range from $300 to $1,200 per repair. Between $300-$400, for a quick fix and long-term satisfaction, we think that price is right.
The engine has a combustion chamber where the explosions occur, causing the engine to heat up quickly. To protect the engine from overheating and breakdown, coolant flows between the radiator and the engine to maintain a usable temperature. The job of the radiator is to keep the coolant at the right temperature to absorb more heat as it returns to the engine and keep the engine warm.
How To Install Radiator Fan Switch
A radiator fan is required to keep the coolant temperature low enough. If the radiator fan isn’t working properly, it can damage your car, and if you leave it too long without fixing it, thousands of dollars in repairs can be out of pocket.

When you notice that your radiator fan has stopped working or your car isn’t cooling, you need to take some troubleshooting steps to find out what the problem is. If you can’t figure it out, take your car to a mechanic right away to have the problem fixed.
If you prefer to do some work yourself, you can troubleshoot the cooling fan to find out where the problem is and how to fix it. The problem is usually multiple areas, such as the fan motor, heat exchanger, wiring or transmission.
In a new car, you should first make sure the radio fan has stopped working before deciding what to do. If you want to verify that it is working properly, you start the engine and let the car go. Turn on the A/C full blast – this should start the cooling fan immediately. In older cars it usually takes 15-20 minutes for the engine to reach the correct temperature. If there is an engine temperature error, it can damage the radiator. What you do next will depend on when and if the radio fan turns on and if the fan stops working.
If the fan turns on when the A/C is running at maximum volume, but does not work properly when the engine is warm or hot, you may need to check the alternator temperature. This switch is responsible for sending signals to the computer to control the fan.
Your Radiator Fan Stopped Working
If the fan does not turn on, you need to look for a blown fuse or circuit breaker. On older cars you may have a fusible link – it’s a wire inside an insulated plastic block. Try grabbing the end and pulling if the wire stretches, the wire connection may be broken and you will need to replace it.
The last case when testing the radiator fan is when the fan does not turn on after the engine has been running for 20 minutes. You need to make sure your refrigerator reaches the desired temperature, which is usually around 104 degrees Fahrenheit. If so, you may be dealing with a stuck thermostat – meaning the refrigerant is constantly flowing, resulting in a lower operating temperature. These steps can help you determine if your fan is really broken and what to do next to fix it when the radiator fan stops working.
If your fan still fails to turn on, you can test by connecting the fan to another power source. After connecting the direct battery to the radiator fan follow the next steps.
First you need to open the cable connector. Check for damage and clean the connectors to make sure the wires are firmly connected and not damaged.

Second, look at the cables to avoid confusion and determine which are power cables and which are ground wires.
Third, you need to connect the negative terminal of the battery to the ground side of the fan connector. Then connect the battery positive to the other wire. You will need to refer to your vehicle’s service manual to determine if the vehicle has a 4-wire terminal or three terminals, two of which are power and one ground wire.
Fourth, after connecting the fan to the battery, the fan should start. However, if your fan does not start with direct voltage, you will need to test the input voltage to make sure there is no damage to the terminals. If the test shows that there is indeed power, then you have narrowed down the problem to the fan motor. If the fan does not turn on at all or runs at a very low speed, you may also need to replace the fan motor.
If the radiator fan motor or fuse, circuit breakers, and clutch appear to be working properly, you may need to check other components to determine what the problem is with the radiator fan. You will need to refer to your maintenance manual to see other parts of the circuit.

The temperature switch on most cars is connected to the car’s computer or the train’s computer. All you need for this test is the test light.
First you need to connect the test light battery to ground. Second, start the engine and let the car run. Reverse test the connector terminals using a test light – hopefully one end of the connector can illuminate the test light. Now just wait for the engine to reach the correct temperature. After the engine reaches operating temperature, retest the other connector wire. If the light does not come on, you have determined that the switch is not working.
In some vehicles, the coolant controls both the coolant and the radiator fan. In this case, you may need to use a voltmeter to test the temperature sensor. If you don’t have a resistance reading, but you can tell that the ohm reading is the same at low and high temperatures, then you should replace the sensor to adjust the radiator fan.
There are several steps you can take to determine if the fan relay is causing your radiator fan to stop working. The first step you should take is to replace the transmission with another one and make sure it is working properly. If the new relay starts working, you know the old relay is causing the problem.

If you can’t find a transmission that you’re sure is working properly, you can test the transmission using another method. You can use a transmission tester – it will help you solve transmission problems in almost all cars. All you have to do is follow the instructions that come with the device. If you don’t want to buy a relay tester, you can buy a digital multimeter at any electronics or hardware store.
When using a digital multimeter, you must first ensure that the relay you are testing has no visible damaged wires. Second, it is necessary to determine which pins and terminals are part of the control circuit and which are part of the power circuit. After identifying the correct terminal, set the multimeter to “Continuity”. Connect one wire to the power circuit and one wire to the power supply. If you find zero, the power pins on your relay have stopped working and you need to replace the relay. Changing the relay can cause your radio fan to stop working.
After you’ve gone through all the troubleshooting tips to determine which part is causing your radiator fan to stop working, you need to perform a proper diagnosis to determine which part needs to be replaced or repaired. There are several common reasons why the radiator fan may not turn on.
A fuse can blow if a current is tripped in an electronic component, forcing the fuse to cut power to protect the device from overloading. While a blown fuse is not a major problem, it is important to find and fix it. Replacing a blown fuse
