HOW TO REMOVE:

  • PULL THE SPARK PLUG BOOT AND CABLE AWAY FROM THE SPARK PLUG.  IF NEEDED, USE A SPARK PLUG BOOT REMOVING TOOL.  DO NOT GRAB OR VIOLENTLY PULL SPARK PLUG CABLES.
  • BRUSH OR USE COMPRESSED AIR TO BLOW DIRT AWAY FROM THE WELL AREAS BEFORE REMOVING A SPARK PLUG.  (USE GOOGLES TO PROTECT EYES FROM DEBRIS WHEN APPLYING COMPRESSED AIR TO SPARK PLUG WELLS)
  • USE THE CORRECT DEEP SOCKET SIZE TO LOOSEN EACH SPARK PLUG 1 OR 2 TURNS.  (TO REMOVE SPARK PLUGS FROM ALUMINUM HEADS, ALLOW THE ENGIONE TO COOL, AS THE HEAT OF THE ENGINE IN COMBINATION WITH A SPARK PLUG THAT IS STILL HOT, MAY CAUSE THE SPARK PLUG THREDS TO STRIP THE CYLINDER HEAD UPON REMOVAL)
  • REMOVE EACH SPARK PLUG AND PLACE EACH ONE IN A TRAY BY CYLINDER NUMBER, TO HELP IDENTIFY AND RELATE ANY UNUSUAL CONDITION TO THE CYLINDER INVOLVED.
  • VISUALLY INSPECT SPARK PLUGS FOR SIGNS OF WEAR.

HOW TO INSTALL:

  • APPLY DIELECTRIC GREASE INTO THE BOOT AREA TO REDUCE THE CHANCE OF EXTERIOR TRACKING ON THE BUTRESS TOWER OF THE SPARK PLUG.  (THE GREASE ALSO ASSISTS IN PROMOTING A GOOD HEAT TRANSFER BETWEEN THE SPARK TERMINAL SCREW AND BOOT TERMINAL)
  • USE A GAP GUIDE TO MAKE SURE YOUR NEW SPARK PLUGS HAVE THE CORRECT GAP. (AC DELCO GOLD/PROFESSIONAL IRIDIUM SPARK PLUGS ARE PRE-GAPPED DURING MANUFACTURING.  NEVER ATTEMPT TO GAP AN AC DELCO GOLD/PROFESSIONAL IRIDIUM SPARK PLUG.  YOU COULD DAMAGE THE SPARK PLUG)
  • REPLACE ANY INCORRECTLY GAPPED AC DELCO GOLD/PROFESSIONAL IRIDIUM SPARK PLUGS WITH PLUGS THAT ARE CORRECTLY GAPPED.
  • INSTALL SPARK PLUGS TO THE PROPER TORQUE PER THE MANUFACTURERS' SPECIFICATION
