How to replace a spark plug on GMC Acadia?

The first procedure when replacing a Spark Plug should be removing the Ignition Coil from the engine. Concrete measures must be taken to clear the Spark Plug recess of dirt since unrestrained debris entry into the Cylinder Head can harm the engine and contaminate the Cylinder Head threads thus preventing proper plug installation; utilize a thread chaser to purge thread contaminants followed by compressed air cleaning of the Spark Plug cavity. Wait for the engine to cool down until you remove the spark plugs because working on hot metal might damage the Cylinder Head threads by gripping plug threads. The installation of new spark plugs requires using only the specified plugs for the vehicle because using plugs with extreme temperature differences can harm the engine profoundly. All new and reconditioned spark plugs need to go through a gap check with a round feeler gauge to prevent engine performance issues or damage that occurs from wrong gaps. When installing the Spark Plug let the threads glide smoothly into the Cylinder Head until the plug reaches complete seat position; a thread chaser helps clean threads when the plug shows signs of cross-threading or improper installation to avoid overheating and exhaust blow-by and thread damage. Finally, fit the Spark Plug into place before tightening it to 20 n.m (15 lb ft) then reinstallation of ignition coils.
