Replacing the Spark Plugs on a Ford Aerostar Video
Q. How do you access the spark plugs on a Ford Aerostar?
A. There are three spark plugs on the driver side and three on the passenger side. By removing the two front tires you will see a "cut out" inside the wheel well. From that vantage point you should be able to access all 6 of the Ford Aerostar's spark plugs.
