How to Replace the Spark Plugs on a 2001 Ford Expedition

Replace the spark plugs in your 2001 Ford Expedition at home, and save time and money. To keep your Expedition in top running condition, you need to perform regular maintenance. One of the most important things to replace in your vehicle is the spark plugs. If your spark plugs are burned out or damaged, your engine will run roughly and get poor gas mileage.

Instructions

1

Pop the hood, and find the ignition coils under the intake manifolds, located near the top of the engine. Remove the coils with the socket wrench set. Note where each coil came from, as you will need to put them back in place later. Under the coils, you will find the spark plugs.

2

Remove the spark plugs with a wrench. If they are slightly difficult to remove, spray them with WD-40 to loosen them.

3

Look up the gap size in the Owners Manual. Set the gap, using the spark plug gapper. Install the new spark plugs into the engine block with the spark plug wrench. Dont turn them too tightly.

4

Put the ignition coils back in place, and secure them. Lower the hood of the vehicle.
