    Steps to Change Spark Plugs in a Jeep JK

    • Step 1: Make sure the engine is cool before starting any work.
    • Step 2: Locate the spark plugs. In a Jeep JK, the spark plugs are located on top of the engine, underneath the ignition coil pack.
    • Step 3: Remove the ignition coil pack by disconnecting the electrical connector and removing any retaining bolts or clips.
    • Step 4: Use the appropriate spark plug socket size determined from the chart above to remove the spark plugs. Attach the socket to a socket wrench and carefully loosen each spark plug by turning counterclockwise.
    • Step 5: Once the spark plugs are loose, remove them by hand and inspect their condition. If they are worn or damaged, it’s recommended to replace them with new ones.
    • Step 6: Install the new spark plugs by hand, making sure they are threaded correctly. Then, use the spark plug socket and wrench to tighten them securely, but be careful not to overtighten.
    • Step 7: Reinstall the ignition coil pack by connecting the electrical connector and securing it with any retaining bolts or clips.
    • Step 8: Repeat the process for each spark plug until all of them have been replaced.
    • Step 9: Once all the spark plugs are replaced, start the engine and listen for any abnormal noises. If everything sounds normal, you have successfully changed the spark plugs in your Jeep JK.
