2000 Ford Taurus Replace Spark Plugs
Spark plugs that are worn out, fouled with carbon deposits or have bent electrodes will lead to reduced fuel mileage and poor engine performance. You need to inspect and possibly replace the spark plugs in your Ford Taurus at four years or 60,000 miles. Removing and installing the spark plugs on a 2000 model varies slightly depending on whether or not it has an overhead camshaft engine.
 Tools Used
|Spark plug removal tool|
|Spark plug socket|
|3/8 inch rubber hose|
 Replace Spark Plugs
- Disconnect the car's negative battery cable.
- Remove the individual spark plug's ignition coil if the car has an overhead camshaft engine, removing the screws for the coil with a screwdriver and setting the coil aside.
- Pull out the spark plug wire at the plug's end, grasping it by the boot and not the wire itself. A plug wire removal tool that looks like a large pair of tweezers with alligator teeth can help.
- Blow all dirt and debris out of the spark plug hole using compressed air.
- Insert a ratchet wrench with a spark plug socket into the hole and turn it counterclockwise to remove the spark plug.
- Coat the threads of the new spark plug with a small amount of anti-seize compound, making sure you don't get any of the compound on the electrodes or the porcelain surface.
- Thread the spark plug into its hole by hand as far as you can and then tighten it the rest of the way with the ratchet.
- Connect the spark plug wire to the spark plug, twisting the boot into position.
- Re-install the ignition coil if needed, using its mounting screws and the screwdriver.
- Reconnect the battery cable.
 Tips & Warnings
- Avoid cross-threading the spark plugs with the threads in the holes. Placing a piece of 3/8 inch rubber hose on the plug will help you properly twist the plugs in place; if the hose slips off the plug, it is cross-threading.
