Steps to Change Spark Plugs in Subaru Outback
If you’re planning to change the spark plugs in your Subaru Outback, here are the steps to follow:
- Make sure the engine is cool before starting.
- Locate the spark plugs. In most Subaru Outback models, the spark plugs are located on top of the engine, beneath the ignition coil.
- Remove the ignition coil by disconnecting the electrical connector and removing the bolts or screws holding it in place.
- Use the appropriate spark plug socket size to remove the old spark plug. Insert the socket onto the spark plug and turn it counterclockwise to loosen and remove the plug.
- Inspect the old spark plug for signs of wear or damage. If necessary, replace it with a new spark plug of the same size and specifications.
- Apply a small amount of anti-seize compound to the threads of the new spark plug to prevent it from seizing in the future.
- Insert the new spark plug into the socket and carefully thread it into the spark plug hole by hand. Once it’s hand-tight, use the socket wrench to tighten it further. Be careful not to overtighten.
- Reinstall the ignition coil by securing it with the bolts or screws and reconnecting the electrical connector.
- Repeat the above steps for each spark plug.
