Step-by-Step Guide

Follow these steps to install the ignition coil in your Subaru Tribeca B9:

Step 1: Disconnect the battery

The first step is to disconnect the negative battery cable. This will prevent any electrical shocks or damage to the electrical system during the installation process.

Step 2: Locate the ignition coil

The ignition coil is located on top of the engine, near the spark plugs. You may need to remove any engine covers or other components to access it.

Step 3: Remove the old ignition coil

Using a socket wrench and a spark plug socket, remove the spark plug wire from the ignition coil. Then, remove the bolts securing the ignition coil to the engine. Gently pull the ignition coil off the spark plug.

Step 4: Install the new ignition coil

Apply a small amount of dielectric grease to the bottom of the new ignition coil. This will help prevent corrosion and ensure a good electrical connection. Place the new ignition coil over the spark plug, and secure it to the engine using the bolts you removed earlier.

Step 5: Reconnect the spark plug wire

Reconnect the spark plug wire to the new ignition coil. Make sure it is securely attached and in the correct position.

Step 6: Reconnect the battery

Reconnect the negative battery cable. Use a torque wrench to tighten the cable bolt to the manufacturer’s specifications.

Step 7: Test the new ignition coil

Start the engine and test the new ignition coil. Make sure there are no misfires or other performance issues. Take the vehicle for a test drive to ensure proper operation.
