How To Install an Electric Fan in Your Vehicle

Installing a new electric fan in your car as replacement for the old one is a great way to improve the over-all performance of your driving machine. A new electric fan, especially when properly installed and matched to the specs and features of the car, could mean more power and better cooling. There may be some claims to disprove this effect, but it goes alongside claims that a new fan indeed creates wonders for the car's performance. Either way, it's a must that you properly install the fan to avoid poor performance or defective wire connections that can endanger not only your car and the other parts and systems comprising it but your own life and the life of your passengers as well. 

Here's a guide that you can use on how to install an electric fan in your vehicle. The steps and procedures may vary depending on the car model or type, but these steps can be used as a general guide.

  1. Remove the old fan and clutch assembly.  Before doing so, be sure that you prepared the needed hand tools such as the clutch pilot tool, cleaning solvent, holmes, and a dial indicator to check the flywheel round out. Marking the parts comprising the clutch assembly must be done for later re-assembly. Remove the small, big and dual bolts one at a time. You can do it diagonally to avoid warping of the clutch cover.
  2. Install the VSC or Variable Speed Control on the top corner of the fan's shroud. This is usually found near the battery.
  3. Wire the electric motors by using the specified connectors. You can check out the given instruction materials to help you determine the wiring diagram holmes along with details on what color should you use. To bundle the wires neatly together, zip ties can be used.
  4. To ensure that the fans will give the needed kick, a temperature sensor can be mounted in between the radiator core fins. If you want the power to run directly from the battery to the variable speed control, a 10 AWG red wire can be used.
  5. Install the fuse holder in a convenient spot, but see to it that you don't insert the fuse until the fan is ready to be used. You can check out your car's specs to determine the amount of amp that the fuse must have.
  6. For the A/C compressor, splice into the power wire. You can then solder and seal the new connection to turn on the fan when your car's air conditioning unit is not functioning.
  7. Plug the needed wiring into the variable speed control. For a spare connection, you can run a power wire in the fuse box.
  8. Finally, you can mount the fuse and test the newly installed electric fan in your car.

See to it that you did the right steps. To ensure safety, better check out your car's specs and features to determine the right electric fan replacement and accessories like a fan heater. Aside from these features, check out the wiring and mounting points to avoid dangerous electrical problems.
