How to replace spark plugs on 2002 Chevrolet Express 2500?

The process starts by removing Spark Plug Wires followed by a 1 or 2 turn looseness of each Spark Plug. Work with a brush or air blast to clean the Spark Plug dirt markings until complete. After you remove each Spark Plug individually put them in separate trays which match the cylinder order. Each Spark Plug washer needs proper installation before inspecting the gap for adjustment to achieve a reading of 1.524 mm (0.060 in). Start the spark plugs manually in their designated cylinders before applying force according to these specifications: 15 n.m for used heads and 20 n.m for new aluminum heads and 30 n.m for new iron heads. Spark Plug Wires must be put back into their original position.
