How to replace a spark plug on Chevrolet Silverado 3500 Classic?

First step starts by taking off the Spark Plug wire which leads to the subsequent step of loosening the Spark Plug between 1 to 2 turns. Before uninstallation of the Spark Plug use either compressed air or a clean brush to clean away dust from its surrounding area. When dealing with multiple plug removals then set each component into trays which display cylinder identification numbers. The correct placement of the Spark Plug washer must be followed by checking the Spark Plug gap before adjusting it to 1.016 mm (0.040 in). The Spark Plug installation begins with hand starting the plug in its designated cylinder while applying 15 n.m torque (11 lb ft) for used heads or 20 n.m torque (15 lb ft) for new heads. The procedure concludes by placing the Spark Plug wire.
