8D - 16 IGNITION SYSTEM
REMOVAL AND INSTALLATION (Continued)
SPARK PLUG—2.4L
Failure to route the cables properly could cause the
radio to reproduce ignition noise, cross ignition of the
spark plugs or short circuit the cables to ground.
NOTE: REMOVE cables from coil first before
removing spark plug insulator.
REMOVAL
Always remove the spark plug cable by grasping
the top of the spark plug insulator, turning the boot
1/2 turn and pulling straight up in a steady motion.
(1) Remove the spark plug using a quality socket
with a rubber or foam insert.
(2) Inspect the spark plug condition. Refer to
Spark Plug Condition in this section.
INSTALLATION
(1) To avoid cross threading, start the spark plug
into the cylinder head by hand.
(2) Tighten spark plugs to 28 N·m (20 ft. lbs.)
torque.
(3) Install spark plug insulators over spark plugs.
Ensure the top of the spark plug insulator covers the
upper end of the spark plug tube.
(4) Install spark plug cable to coil.
SPARK PLUGS AND CABLES—2.5L
When replacing the spark plug and coil cables,
route the cables correctly and secure them in the
appropriate retainers. Failure to route the cables
properly can cause the radio to reproduce ignition
noise, cross ignition of the spark plugs or short cir-
cuit the cables to ground.
CAUTION: Never attempt to file the electrodes or
use a wire brush for cleaning platinum plugs. This
would damage the platinum pads which would
shorten spark plug life.
Apply a very small amount of anti-seize compound
to the threads when reinstalling the vehicle's original
spark plugs that have been determined good. Do not
apply anti-seize compound to new spark plugs.
NOTE: Anti-seize compound is electrically conduc-
tive and can cause engine misfires if not applied
correctly. It is extremely important that the anti-
seize compound doesn't make contact with the
spark plug electrodes or ceramic insulator.
SPARK PLUG REMOVAL—#2, #4 or #6
Always remove the ignition cable by grasping at
the spark plug boot turning, the boot 1/2 turn and
pulling straight back in a steady motion.
(1) Prior to removing the spark plug spray com-
pressed air around the spark plug hole and the area
around the spark plug.

(2) Remove the spark plug using a quality socket
with a rubber or foam insert.
(3) Inspect the spark plug condition. Refer to
Spark Plug Condition in this section.
INSTALLATION
(1) To avoid cross threading, start the spark plug
into the cylinder head by hand.
(2) Tighten spark plugs to 28 N·m (20 ft. lbs.)
torque.
(3) Install ignition cables over spark plugs.
SPARK PLUG REMOVAL—#1, #3 or #5
(1) Disconnect negative
jumper terminal.
(2) Unplug connectors from MAP and intake air
temperature sensors (Fig. 33).
