With the engine cover removed, locate the ignition coils. They are typically situated on top of the engine, connected to the spark plugs.
Step 4: Remove the Old Ignition Coils
Start by disconnecting the electrical connector from each ignition coil. Press down on the tab and pull the connector off gently.
Next, use a socket wrench to remove the bolts securing the ignition coils. Carefully lift each coil out of its socket and set them aside.
Step 5: Clean the Coil Sockets
Before installing the new Bosch ignition coils, clean the coil sockets using a wire brush or cleaner. This ensures a good connection and optimal performance.
Step 6: Install the New Bosch Ignition Coils
Take the new Bosch ignition coils and align them with the sockets. Gently press down to secure them in place.
Reinsert the bolts and tighten them using a torque wrench to the manufacturer’s specifications.
Step 7: Reconnect the Electrical Connectors
Once the coils are securely installed, reconnect the electrical connectors. Ensure they click into place for a solid connection.
Step 8: Replace the Engine Cover
With the ignition coils installed and connected, replace the engine cover. Secure it with the bolts you removed earlier.
Step 9: Reconnect the Battery
Reconnect the negative terminal of the battery using a socket wrench. Ensure it is tight and secure.
Step 10: Test the Vehicle
Finally, start the engine to test the new ignition coils. Listen for any unusual sounds and ensure the engine runs smoothly.
