• Q: How to replace spark plugs safely and effectively on 2005 Chevrolet Classic?

  A: The replacement of spark plugs must wait until the engine cools down to avoid aluminum cylinder heads damage. The initial step involves removing the ignition coil housing before applying a Spark Plug socket to remove sparks plugs. After removal the technician needs to dry Spark Plug holes thoroughly with compressed air. Double-check spark plugs for any damage routines permit. A round wire type Spark Plug gap gage should be used to gap new spark plugs to a precise measurement of 1.14 mm (0.045 in). The use of Spark Plug sockets enables proper plug installation while users should avoid applying anti-seize compound directly on spark plugs to safeguard against head thread damage and excessive torque. As the final step tighten the spark plugs to 20 n.m (15 lb ft) before putting back the ignition coil housing.
