    2000 Subaru Outback Spark Plug Socket Size

    Overview

    If you own a 2000 Subaru Outback and are looking to change the spark plugs, it’s important to know the correct socket size to use. Using the wrong size socket can lead to damage to the spark plug or the socket itself. In this article, we will provide you with the information you need to determine the spark plug socket size for your 2000 Subaru Outback.

    Identifying the Correct Socket Size

    To determine the spark plug socket size for your 2000 Subaru Outback, you can refer to the owner’s manual or consult the manufacturer’s specifications. However, if you don’t have access to these resources, you can also measure the spark plug hex size directly.

    Measuring the Spark Plug Hex Size

    To measure the spark plug hex size, you will need a ruler or a caliper. Follow these steps:

    1. Ensure the engine is cool before attempting to remove the spark plugs.
    2. Locate the spark plugs on your 2000 Subaru Outback. They are typically found on the top of the engine, connected to the ignition coils.
    3. Remove the spark plug wire from the first spark plug by gently pulling it off.
    4. Using a ruler or caliper, measure the distance across the flats of the spark plug hex. The flats are the sides of the hexagon-shaped part of the spark plug.
    5. Once you have the measurement, refer to the chart below to determine the corresponding socket size.

    Using the Correct Socket Size

    Once you have determined the spark plug socket size for your 2000 Subaru Outback, you can proceed with changing the spark plugs. Here are the general steps to follow:

    1. Ensure the engine is cool.
    2. Remove the spark plug wire from the first spark plug.
    3. Using the correct socket size, attach it to a ratchet or extension.
    4. Place the socket over the spark plug and turn it counterclockwise to loosen and remove the spark plug.
    5. Inspect the spark plug for any signs of damage or wear. If necessary, replace it with a new spark plug of the same size and specifications.
    6. Apply a small amount of anti-seize compound to the threads of the new spark plug.
    7. Insert the new spark plug into the spark plug socket and carefully thread it into the spark plug hole by hand to avoid cross-threading.
    8. Tighten the spark plug using the socket and ratchet, turning it clockwise until it is snug. Be careful not to overtighten.
    9. Reattach the spark plug wire to the spark plug.
    10. Repeat the process for the remaining spark plugs.
