If your car has an exhaust fan, it’s important to keep the ducts clean. Dirty ducts can cause poor air flow and increase the chances of engine failure. Here are four easy steps to cleaning your exhaust fan ducts:

  1. Open the hood and remove the fan cover.
  2. Locate the two screws that hold the fan in place and remove them.
  3. Lift up the fan blade and clean all of the dust, dirt, and debris that is attached to it with a vacuum cleaner or a brush. Make sure to get into all of the nooks and crannies.
  4. Replace the fan blade and screws, then reattach the cover. ..
