• Q: How to service and repair spark plugs on 2003 GMC Safari?

  A: Service and repair of spark plugs begins with wire removal then turning each Spark Plug by 1 or 2 turns before cleaning the area. Before removing the spark plugs work to clean the nearby soiling with either a brush or compressed air stream. Take out each Spark Plug separately while labeling the tray with cylinder numbers. Ruud vican 255 4100 Spark Plug washers should be correctly set during installation and Spark Plug gaps must be checked for adjustments until reaching the proper measurement of 1.524 mm (0.060 in). Utilize hand tools to install spark plugs in their designated cylinders before torquing them to the recommended values: 15 n.m for used heads or 20 n.m when using new aluminum or 30 n.m for new iron heads. Reinstall all Spark Plug Wires as the last step of the process.
