Step 1: Let car cool down Park your car and wait for it to cool down. This may take a few hours, since the spark plugs are among the hottest parts of your engine. Step 2: Locate spark plugs Pop open the hood and locate your spark plugs by referring to your owner's manual. Step 3: Remove one spark plug Remove one spark plug wire from the end of the row by pulling its boot, or the little cap where it connects to the engine -- not by yanking on the wire itself. Tip You can also use a spark plug wire puller to easily detach the wire. Step 4: Attach spark plug to socket wrench Attach the spark plug socket to the socket wrench. You may need to use a swivel joint and/or a socket wrench extension to reach the spark plug. Step 5: Remove spark plug Remove the spark plug by turning the socket wrench counterclockwise. Step 6: Make sure hole's clean Make sure that the spark plug hole is clean. If necessary, use a rag and rubbing alcohol or compressed air to clean the spark plug hole. Step 7: Install new spark plug Carefully install a new spark plug into the empty hole and tighten it by hand. Step 8: Secure new spark plug Use the socket wrench to secure the new spark plug in place. Step 9: Reconnect spark plug wire Reconnect the spark plug wire onto the new spark plug. Tip Changing your spark plugs one at a time prevents incorrect installation that can affect the car's timing and engine performance. Step 10: Move on to next spark plug When you have successfully changed a spark plug, move on to the next one until you have finished installing all new plugs. Did You Know? Diesel engines don't use spark plugs.
