How to replace the right side spark plug(s) safely and correctly on GMC Yukon?

The right front wheelhouse liner should be removed first so spark plugs can be reached through the wheel opening. All high voltage component service and connection work requires execution of the high voltage disabling procedure along with personal protection equipment use and correct procedures to stop serious injury or death. The procedure requires workers to learn how to disable high voltage and follow tests and evaluate which conditions cause high voltage to always exist. Start by conducting the service disconnect followed by removing the Spark Plug wire through a half-turn twist on the boot before pulling only from the boot itself. Clean dirt from around the Spark Plug by brushing or blowing compressed air and remove the plug to a tray labeled with cylinder numbers of multiple plug removals. Insert the Spark Plug washer properly after inspecting the gap and adjusting it as necessary before hand-starting the plug into the target cylinder. Secure the Spark Plug with 15 nm (11 lb ft) torque while reattaching the Spark Plug wire. After checking that each boot seats correctly by pulling sideways you should reinstall any loose.bootstrap. Replacement of any right side Spark Plug(s) requires right front wheelhouse liner reinstallation before conducting the service reconnect.
