Hello!

Here is the spark plug removal procedure from the factory service instructions:

_______________________________

CAUTION: Note routing of secondary ignition cables before removing. Failure to route cables properly may result in radio interference, ignition cross fire, or ignition short to ground.

NOTE: Keep plugs in order removed. A plug, that looks different from the rest, could be a problem indicator.

SPARK PLUG #3 AND #5

REMOVAL

  1. Remove the resonator.
  2. Remove intake strut to cylinder head bolt at cylinder head.
  3. Loosen bolt for intake strut at intake.
  4. Swing strut away.
  5. Grasp the spark plug boot/shield assembly as close as possible to the spark plug. Twist the boot/ shield assembly slightly to break the seal with the plug and pull straight out
  6. Remove spark plug

 

INSTALLATION

  1. Install spark plug and tighten to 28 Nm (20 ft lb) .
  2. When installing the spark plug cables, make sure spark plug insulator and terminals are fully seated.
    • A click sound should be heard or felt when the terminals are properly attached.
  1. Install the cable into the retaining bracket.
    • Make sure that they are also attached to the rear retaining clip mounted on the rear of the intake manifold.
  1. Swing strut back into place.
  2. Install intake strut bolt to cylinder head at cylinder head.
  3. Tighten bolt to intake strut at intake.
  4. Tighten bolt at cylinder head.
  5. Install the resonator.

SPARK PLUG #1

REMOVAL

  1. Remove the accessory drive belt.
  2. Remove the 4 bolts from the upper half of the generator bracket.
  3. Push the Generator rearward.
  4. Grasp the spark plug boot/shield assembly as close as possible to the spark plug. Twist the boot/ shield assembly slightly to break its seal with the plug and pull straight out. Do not use pliers, pull on the ignition cable, or pull the spark plug boot at an angle. This could damage the spark plug insulator, terminal, or the insulation. Wipe spark plug insulator clean with a dry cloth before installation.
  5. Remove spark plug INSTALLATION
  1. Install spark plug and tighten to 28 Nm (20 ft lb) .
  2. When installing the spark plug cables, make sure the coil or spark plug insulator and terminals are fully seated.
    • A click sound should be heard or felt when the terminals are properly attached.
  1. Pull Generator back into place.
  2. Install upper Generator bracket with the 4 bolts.
  3. Install the accessory drive belt, refer to Cooling System.

OTHER PLUGS

REMOVAL

  1. Spray compressed air around spark plug to prevent foreign material from entering combustion chamber.
  2. Remove spark plug wire by grasping boot and turning 1/2 turn while pulling boot back in a steady motion.
  3. Remove spark plug using socket with foam insert. INSPECT FOR:
    • Color of Deposits
    • Excessive Deposits
    • Electrode wear
    • Cracked or Damaged Threads Or Insulator
    • Worn or Bent Electrodes
    • Damaged Gasket

INSTALLATION

  1. Start plug in cylinder head by hand, to prevent cross threading.
  2. Torque spark plugs to 20 ft-lbs (28 Nm) .
  3. Install secondary ignition cables on spark plugs

CAUTION: When replacing spark plugs because of a high speed miss condition; wide open throttle operation should be avoided for approximately 80 km (50 miles) after installation of new plugs. this will allow deposit shifting in the combustion chamber to take place gradually and avoid plug destroying splash fouling shortly after the plug change.

___________________________________

Replacing the plugs should take an experienced Chrysler technician 1.6 hours, according to the labor guide. If you are unfamiliar with this repair, a more realistic labor time would be somewhere around 3 hours.
