How To Change Spark Plugs On Nissan Altima

You want to know how to change the spark plugs on your Nissan Altima. Changing the spark plugs on your Nissan Altima is an easy job. With the right tools and replacement parts, you can change spark plugs on Nissan Altima in no time.

Things you need to change spark plugs on Nissan Altima:

  • New spark plugs
  • Spark plug socket
  • Ratchet
  • Extension bar
  • Wire feeler gauge
  • Wrench
  • Car manual
  1. Park your Nissan Altima in your driveway or your garage. Let the car cool off. Disengage the hood and pull it up. Secure the hood with the secure arm of your car. Locate the battery and disconnect the negative battery cable from the battery.
  2. Locate the spark plug wires on your Nissan Altima. Pull one spark plug wire off the first spark plug. Make sure you pull the wire off as close as you can get to the spark plug. You do not want to damage the spark plug wire.
  3. Take your ratchet, connect the extension bar, and connect the spark plug socket to the end. Take your ratchet and put it into the hole where your spark plug is located. Engage your spark plug with your spark plug socket. Turn the ratchet counter clockwise to remove the spark plug. Take the first spark plug out of the car. Look at the spark plug to see what kind of condition it looks to be. A completely burnt plug can tell you other things about your car.
  4. Take a new spark plug out of the package. Compare it to the old spark plug. When you bought the spark plugs at the auto parts store, they sold you spark plugs made for your Nissan Altima. Eye the plugs to make sure they did not make a mistake. Take the new spark plug and gap it.
  5. Your car manual will have the gap distance for your Nissan Altima’s spark plugs. The auto parts store can give you the same information. Gap your spark plug by placing the wire feeler gauge between the electrodes of the spark plug. When the spark plug is (gapped) correctly, the spark plug is ready to go into the car.
  6. Take the spark plug and put it in the spark plug hole. If you can, start the spark by hand. You put the spark plug in the car the same way you took the spark plug out of the car. You screw in the spark plug clockwise until it stops to move. Tighten the spark plug slightly when it stops moving. You do not want to over tighten the spark plugs. Over tightened spark plugs will strip the spark plug hole.
  7. Take the spark plug wire and replace it over the top of the spark plug. You may hear a popping noise when you connect the spark plug wire. This is normal and means the connection is good.
  8. Do the same steps with all of the spark plugs in your Nissan Altima. When all spark plugs have been replaced, reconnect the negative battery cable, put your hood down, and start your car. 

Tips

  • Refer to car manual about how long between changing your spark plugs
  • Buy the correct spark plugs for your car
  • More expensive spark plugs are not always better
  • Do not over tighten the spark plugs
  • Make sure the gap is correct
