- Park your Forester.
- Pop the hood.
- Disconnect the battery.
- Remove the engine cover, if applicable.
- The ignition coil is on top of the engine, in the middle. There are four spark plug wires connected to it. With a white marker, write a number on each spark plug wire. It’s important that the spark plug wires go back in the right places after you install the new ignition coil.
- Disconnect all the spark plug wires from the ignition coil.
- There are either 2 or 3 bolts securing the ignition coil in place. Remove all of them.
- Remove the ignition coil.
- Put the new ignition coil in. Secure it in place with the 2 or 3 bolts you just removed.
- Connect all the spark plug wires according to the numbers you marked on them.
- Place the engine cover back on the engine, if applicable.
- Connect the battery.
- Start your Forester and then see if any of the previous symptoms persist. (You can see a list of the symptoms of a bad ignition coil here.)
