The radiator fan is very essential when it comes to cooling your vehicle. Your vehicle engine must remain cool to prevent overheating and breaking down completely. The radiator fan is responsible for blowing or pulling air around the radiator to keep it cool. Most manufactured radiators land with an electric fan which is easy to change or repair if need be.
Step 1 – Let Your Car to Cool
If you have just noticed the problem and your engine has been running, it is very essential to allow the engine and radiator to fully cool so that you do not burn your hands or create any additional damage to the engine.
Turn off the ignition and let the vehicle sit for 30 minutes to an hour. As long as there is no direct sun on the engine, you can open up the hood of your vehicle to speed up the cooling process.
Step 2 – Take out the Fan
Check for your radiator and find the cooling fan. The fan should be found in the front or the back of the radiator, making it easier to access. You will need to screw out any bolts holding it in with your ratchet. There are often four bolts on most radiators: two on top of the fan and two below.
Once the bolts are taken out, you should be able to pull it out. Ensure to be careful and pull it out slowly since it is connected to a wire at the bottom of the fan. Simply unhook the wire and disconnect the fan, taking it completely out of the radiator.
Step 3 – Clean the Fan
Immediately you set the fan down on your workspace, look at it to see if there is any grease, tar, or other substances stuck to the fan or the blades. If there is, you will have to clean it off. The easiest way to perform this is to dip a rag into degreaser and clean off the bad areas.
Use pipe cleaners to clean out the small components of the fan, gently rubbing it back and forth to take out any unwanted substances or materials.
A dirty fan could make your radiator fan to not work, and with a little simple cleaning, you may be able to fix it entirely. Check it with 12 volts of electricity to see if it works. If you do not have a way to test it easily, follow the next step as a precaution before changing your fan.
Step 4 – Check Your Fuses
Check where the fuses are kept in your fan and check them. With some fuses, you can inform if they are broken by holding them up to the light and seeing if a circuit is connected. You can equally use a fuse multimeter to check if there are any bad ones. Change old fuses with new ones and test your fan again if possible.
Step 5 – Re-connect the Fan
Change the fan into your radiator, remembering to plug it back into the wire. Bolt it into position with your ratchet and test it by starting your vehicle.
Most times, following these steps will fix your radiator fan. If you continue to have issues, you will need to take it in to a professional and perhaps have it changed.
