How to replace a spark plug on Buick LaCrosse?

So you can replace spark plugs start by flipping off the ignition and then take out the Ignition Coil. Use a compressed air source with safety glasses and precautions while clearing Spark Plug cavities from debris. To avoid Cylinder Head contamination that impedes new plug seating a thread chaser should be used for cleaning the Spark Plug recess. Wait for the engine to reach normal temperature before taking out the Spark Plug to stop thread seizure from happening. For new Spark Plug installation maintain the gap at the Spark Plug gap specification while using only vehicle-approved plugs because non-standard plugs will damage the engine severely. A round feeler gauge should be used to check the gaps of new and reconditioned spark plugs due to possible adjustments during handling. Thread the new Spark Plug into the Cylinder Head until it reaches complete seating while monitoring its smooth progress; if any issues persist then use a thread chaser to prevent cross-threading and incomplete seating since both conditions increase risks of overheating and thread damage. Torque the Spark Plug to 20 n.m (15 lb ft) before putting back the Ignition Coil.
