REMOVAL

Fig. 1: Remove spark plug wires one at a time by gently twisting and pulling — make sure to label all plug wires so that they do not get mixed up

  1. Raise the hood and locate all the spark plugs.
  2. If the spark plug wires are not numbered, mark each one with a small piece of masking tape. Print the number of the cylinder on the piece of tape.
  3. Disconnect the wire from the plug by grasping, twisting and pulling the molded cap from the plug. Do not simply yank the wire from the plug as the connection inside the cap can become damaged.
  4. Using a spark plug socket, loosen the plug a few turns.
  5. If compressed air is available, blow out the area around the base of the spark plug to remove foreign matter.
  6. Remove the plug the rest of the way and inspect them. It is a good idea to inspect the plugs whether or not they are going to be reused.
