How to service and repair spark plugs on 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.

How to replace spark plugs on Chevrolet Express 3500?

You must remove Spark Plug Wires before starting the replacement process. A proper tightness of one to two turns is needed when accessing each Spark Plug from the wheel wells. Before installing new spark plugs users must remove dust and debris from the plug areas with either a brush or air plenum. Set aside a tray with each cylinder number to hold plug removals in order that you take them out. Examine the Spark Plug washer gap following proper installation before using correct tools to adjust it to match the specific measurement of 1.524 mm (0.060 in). Apply torque at 15 n.m (11 lb ft) when installing spark plugs into 4.3l, 5.0l, and 5.7l iron-headed engines yet use 20 n.m (15 lb ft) for 7.4l iron-headed units while new iron-headed spark plugs need 30 n.m (22 lb ft) torques regardless of engine capacity. Reinstall the Spark Plug Wires during the last step of the procedure.
