How to service and repair spark plugs on 2003 Chevrolet Express 3500?

A proper Spark Plug service requires the removal of Spark Plug Wires followed by gentle rotation of each Spark Plug 1 or 2 turns. Begin by brushing off debris near the spark plugs and follow with an air blast before taking them out one by one while labeling each Spark Plug with cylinder numbers on separate trays. Before installation the Spark Plug washer positioning needs to be checked and Spark Plug gap measurements should be taken for adjustment until reaching 1.524 mm (0.060 in) specifications. The hand-installed spark plugs must get controlled tension to achieve the following specifications: 15 n.m (11 lb ft) for used heads and 20 n.m (15 lb ft) for new aluminum heads with 30 n.m (22 lb ft) for new iron heads. The last step includes reinstallation of Spark Plug Wires.
