How to replace spark plugs on GMC Yukon XL 1500?

Begin Spark Plug replacement by disconnecting the wires and turning each device by 1 or 2 notches. The cleaning process for spark plugs involves brushing off debris with air pressure or a brush followed by single plug removal into tray identification marked for each cylinder. Check the placement of individual Spark Plug washers before inspecting the Spark Plug gap for proper length which should be 1.524 mm (0.060 in). Beginning with each cylinder's specific Spark Plug the technician must perform hand torques followed by the appropriate tightening force. For utilized heads the torque value should remain at 15 n.m (11 lb ft) and for aluminum heads the value should be 20 n.m (15 lb ft) while new iron heads require 30 n.m (22 lb ft). Reinstall Spark Plug Wires as the last step in the procedure.
