How to Replace Spark Plugs in a Chevrolet Cruze?

[DiVivienne]

Steps to replace spark plugs in a Chevrolet Cruze: Open the hood, lift the plastic engine cover, remove the high-voltage ignition wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage ignition wires in the correct firing order and reattach the cover. If the spark plugs are damaged, it can directly cause issues such as electrical leakage in the ignition system, increased fuel consumption, reduced engine power, and most notably, difficulty in starting the vehicle, affecting normal operation. Severe spark plug erosion, including blistering at the top, damage, or melted electrodes, indicates that the spark plug is worn out and should be replaced.
