2002 GMC Safari Parts Questions & Experts Answers

• Q: How to replace spark plugs on 2002 GMC Safari?

  A: Begin the Spark Plug replacement by taking off the Spark Plug Wires then gently turn each Spark Plug one or two rounds. Users should clean the Spark Plug area using a brush or air blow before individual plug removal into labeled cylinder trays. Check the correct placement of every Spark Plug washer and verify the Spark Plug gap requires adjustment until it meets 1.524 mm (0.060 in). The spark plugs must receive hand-torque application in their designated cylinders before receiving the appropriate tightening force values. Used heads require 15 n.m (11 lb ft), new aluminum heads need 20 n.m (15 lb ft) and new iron heads should reach 30 n.m tightening force (22 lb ft). Install the Spark Plug Wires after the completion of the instructed steps.
