How to replace spark plugs on GMC Safari?

The first thing to do when changing spark plugs is to pull off the Spark Plug Wires and unscrew the plugs a little. Clear away dirt from the spark plugs with either a brush or compressed air, then take out each Spark Plug one by one and put it into a tray with its cylinder number written on it. As you put in the spark plugs, confirm the washers are set right and use a gauge to adjust the gap until it's 1.524 mm/0.060 in. Place the spark plugs in their right cylinders, then fasten them with the proper force shown here: for used heads, tighten to 15 n.m (11 lb ft); if the heads are used, tighten them to 15 n.m (11 lb ft); tighten new aluminum heads to 20 n.m (15 lb ft), and new iron heads to 30 n.m (22 lb ft). Make sure to put the Spark Plug Wires back into their places.
