How to Replace Spark Plug Wires on 2007 GMC Sierra 1500?

Begin the Spark Plug wire replacement process by carefully noting their proper placement. Use either a tool or carefully twist the boot 1/2 turn before pulling it from the Spark Plug (1, 2). The next step entails removing Spark Plug wire boots from the Ignition Coil through the same procedure. Next cut open the Spark Plug wire separators so you can pull out the Spark Plug Wires. Reviewing boot to wire fit before installation is essential to maintain Spark Plug wire core integrity and prevent engine misfire or crossfire because improper seating leads to wire damage. For installed old Spark Plug Wires the application of dielectric grease gm pn 12345579 (Canadian PN 10953481) or equivalent inside Spark Plug wire boots must occur. Follow these installation steps: put Spark Plug Wires in place, make sure Spark Plug wire separators get closed, then secure Spark Plug wire boots to each Ignition Coil before attaching (1, 2) each boot to the Spark Plug. For proper Spark Plug wire examination check their route (1, 2, 3, 4, 5, 6) while also checking boot seating by pushing all boots sideways before reboots and fresh dielectric grease application in each boot during installation operations.
