How to Replace Spark Plugs in a Toyota Camry

How to Replace Spark Plugs in a Toyota Camry

Spark plugs are located in the internal combustion engine and produce a spark to ignite the fuel. You should replace platinum-tipped spark plugs in a Camry every 60,000 miles. The back three spark plugs on the V6 are difficult to reach without a socket extension. Buy well-insulated replacement spark plugs to ensure the spark happens at the tip of the electrode.

Difficulty:
Moderate

Instructions

things you'll need:

  • Replacement spark plugs
  • Compressed air
  • Feeler gauge
  • Thread chaser
  • Spark plug socket
  • Socket extensions
  1. Removing the Spark Plugs

    • 1

      Unhook the negative battery cable whenever working with metal tools that could come in contact with the battery and cause a spark.

    • 2

      Remove the ignition coil from the Camry's cylinder head with a torque wrench.

    • 3

      Twist the spark plug wire boot loose, and then pull it off the plug. Inspect the boot for damage and replace it if necessary.

    • 4

      Blow into the spark plug well with compressed air to remove harmful contaminants. Alternatively, vacuum out the well or brush away debris with a clean towel.

    • 5

      Grab the recessed plug with a spark plug socket and turn counterclockwise to remove it. A spark plug socket has a special rubber fitting that grabs the plug.

    Installing the Spark Plugs

    • 1

      Adjust the gap on the replacement plug with a feeler gauge. The gap on a Camry should be .043 inches.

    • 2

      Thread the plug by hand or use a standard socket. If you try to use a spark plug socket, it will grip the spark plug and you won't be able to get the socket out. If it's not threading smoothly, use a thread chaser to clean the threads in a cylinder head.

    • 3

      Tighten the spark plugs to 11 ft-lbs. if installed into the existing cylinder head. On a a new cylinder head, tighten to 15 ft-lbs.

    • 4

      Push the spark plug boot on the plug until it clicks into place. Pull on it gently to make sure it's securely in place.

    • 5

      Repeat all steps for the other spark plugs. Use an extension on the spark plug socket to reach the back spark plugs on the V6.

    • 6

      Reconnect the negative battery cable.

Tips & Warnings

  • Always remove one spark plug at a time so the wires don't get mixed up. If you need to remove all the wires at once, number the wires with tape to keep them straight.

  • Never remove spark plugs on a hot engine. Wait for it to completely cool before beginning or you can damage the cylinder head threads.
