  Q: How to replace a spark plug on Chevrolet Silverado 1500 Classic?

  A: The first step for Spark Plug replacement begins with turning the boot of the Spark Plug wire a 1/2 turn counterclockwise before removal and pulling on the boot itself rather than the cable or using a specialized tool. After turning the Spark Plug 1 or 2 rotations you should brush away dust in the area or use air blast methods before removing the Spark Plug. Multiple plugs need separate trays where the correct cylinder number marks each container. The correct placement of the Spark Plug washer must be confirmed during installation while you should check and adjust the Spark Plug gap to 1.524 mm (0.060 in) when needed. Fitting the Spark Plug into the specified cylinder requires hand-tightening to 15 n.m (11 lb ft) for used heads while new aluminum heads require 20 n.m (15 lb ft) torque and new iron heads need 30 n.m (22 lb ft).
