  Q: How to replace a spark plug safely and effectively on Cadillac SRX?

  A: Replace a Spark Plug by starting with Ignition Coil removal together with protective eyewear and proper compressed air safety steps. Valve the recess area for the Spark Plug by using a thread chaser to remove contaminants from the threads because any foreign material entering the Cylinder Head would potentially damage the engine. The engine must reach a safe operating temperature after compressed air removes debris from the Spark Plug cavity before attempting to remove the plug to prevent threaded damage. Use only the spark plugs recommended for the vehicle when installing a new Spark Plug to prevent engine damage from sparks of the incorrect temperature range. A round feeler gauge should check the newly installed and rebuilt spark plugs to verify their proper gap measurement follows the Spark Plug gap specification. A thread chaser should be used to check that the Spark Plug threads without issues and reaches total installation depth without creating cross-threading damage that could cause overheating. Follow the manufacturer instructions to install and tighten the Spark Plug until it reaches 20 nm (15 lb ft). Afterward, reinstall all the ignition coils.
