• Q: How to replace a spark plug on 2006 Buick LaCrosse?

  A: The first step to replace a Spark Plug includes shutting off ignition power and removing the Ignition Coil. First place on safety glasses then utilize compressed air to clean the Spark Plug cavity while following compressed air safety protocols. The Spark Plug recess must be cleaned to protect the Cylinder Head threads from contamination which could cause incorrect fitting of the new plug. A thread chaser serves this cleaning purpose. Engines need to cool down before unthreading the Spark Plug to prevent thread damage. Verify that the Spark Plug gap stays at its standard setting while using nothing but the manufacturer-specific spark plugs because improper spark plugs can cause serious harm to the engine. New and reconditioned spark plugs must have their gaps checked with a round feeler gauge because the initial stretches could modify between handling steps. The installation of the Spark Plug requires a thread chaser when needed to avoid cross-threading so it threads easily into the Cylinder Head until complete seat; failure to achieve proper seating could result in overheating or thread damage. Before placing the Ignition Coil re-tighten the Spark Plug to 20 n.m (15 lb ft).
