Replace a Fan Clutch


1. Check for Fan Clutch Problems

The first thing that needs to be done is to be sure that the problem is with the fan clutch. A quick visual inspection of the fan will give you an idea if it is already calling for a replacement. You also have to listen to the sound when the engine is turned on. If there is an annoying and loud sound, this is another indication that it needs a replacement.

Another indication that you have a problem with the clutch is when the engine experiences overheating. Remember, it controls the cooling fans. Therefore, when the fan clutch does not work, the fans will not also provide a cooling effect, and this is why the engine will suffer from heating.

2. Remove the Fan Clutch

Once you are sure that the fan clutch is problematic, proceed to have it removed. Before you can access the fan, you have to remove the air intake hose, fan shroud, and belt. Use the screwdriver to take off the intake hose. Once the screw is loose, take it off and wiggle the hose until it is completely moved out of its place.

After removing the air intake hose, you will now have easier access to the fan shroud. Remove the bolts on both sides.

3. Remove the Fan

After removing the shroud, you will now have easier access to the old fan, and you can have it removed. Use an open-ended wrench to remove the bolts that are attached to the fan. In the case of some designs, you will need to use a pulley locking tool. The latter has the main purpose of preventing the movement of the pulley while you are removing the nut.

4. Install the Fan Clutch

Once you are done with the removal of the old fan clutch, now is the time to have it replaced with a new one. Hold it in place while aligning the bolts. Fasten the bolts and see to it that it is secured. This is an important part of the process. If the fan is not properly positioned, it can loosen and can cause problems in the engine.

5. Install the Shroud and the Hose

After the installation of the new fan clutch, you have to return everything that you had earlier removed. This will include the fan shroud and the air intake hose. See to it that you will bring them back to their original position. As with the fan clutch, check the bolts and the screws to be sure that they are as tight as they should be.

Pro Tips

Aside from learning the way to properly install a fan clutch, the tips mentioned below will also be helpful, especially when it comes to making sure that the problem is with your fan clutch.

Testing your Fan Clutch

Earlier, we noted in this post that the first thing that you need to do is to determine if the problem is really the fan clutch. Aside from a quick visual inspection, there are certain tests that could confirm your initial theory.

To test a fan clutch, here are the things that you need to do.

  • Start the car. After starting the car, proceed to the front and open the hood, which should provide you with a good view of the engine and its components.
  • Provide time so that the engine will stabilize. After a few minutes, the fan should slow down. If there is no sign of slowing down, this is an indication that the clutch is frozen.
  • Another test is to attempt to stop the fan from running. Place a rolled paper and see if the fan will stop. If it stops easily, this means that the clutch needs a replacement.
  • Spinning the fan with your hand will also be another quick test that you can do. There should be some form of resistance as the fan spins. If it requires too much effort to spin or if it rotates easily, these are also signs that you need a new fan clutch.

Types of Fan Clutch

When looking for a replacement for the old fan clutch, keep in mind that there are two common types available, and they have differences in terms of how they work:

  • Thermal Fan Clutch: With high-speed operations, this type is able to provide maximum cooling. It also has disengaged operation, which is great for noise reduction and fuel efficiency.
  • Non-Thermal Fan Clutch: If you are looking for one that is more affordable, this is what you have to choose. Nonetheless, its life expectancy is typically shorter.

The materials needed are quite basic, and the steps are easy to follow. Basically, you just have to remove the air hose intake, fan shroud, and old fan clutch and replace them with a new one.
