• Q: How to service and repair spark plugs on 2000 GMC Safari?

  A: Service technicians must first remove Spark Plug Wires before loosening spark plugs with a limited number of turns and should work through the wheel wells to access most plugs. Use a brush along with air pressure to clean each Spark Plug location before taking out each plug separately so you can place them into marked trays according to cylinder number order. Check that each Spark Plug washer finds its right placement before inspecting the Spark Plug gap for adjustment to reach 1.524 mm (0.060 in) specifications. During (IRON Head-all Subsequent Installations) the technician needs to tighten spark plugs to 15 n.m (11 lb ft) while new iron heads require a torque of 30 n.m (22 lb ft). The last step involves reinstallation of Spark Plug Wires.
