How to replace a spark plug on 2008 Chevrolet Silverado 1500?

The first step before changing the Spark Plug is to detach specific Spark Plug wire boots by extending and twisting the boot 1/2 turn while pulling only on the boot or using intended removal tools. Prior to removing the Spark Plug wipe or air the dirt off adjacent areas before loosening it 1 to 2 turns. Each Spark Plug should be placed in its designated tray that matches the cylinder number during multi-plug removal procedure. When installing new spark plugs users should ensure the washer stays in its correct position while checking to see if the gap needs adjustment. Use hand strength to install the Spark Plug in the Cylinder Head before torquing it to 15 n.m (11 lb ft). The inside of Spark Plug wire boots requires gm pn 12345579 (Canadian PN 10953481) or equivalent dielectric grease before reattaching Spark Plug wire boot(s) to their respective spark plugs.
