INSTALLATION
(1) Install coolant sensor. Tighten sensor to 28 N m
(20 ft. lbs.) torque.
(2) Attach electrical connector to sensor.

SPARK PLUG CABLES

Clean high tension cables with a cloth moistened
with a non-flammable solvent. Wipe the cables dry.
Check for brittle or cracked insulation.
Resistance cables are identified by the words Elec-
tronic Suppression.
SPARK PLUG CABLE SERVICE—3.3L ENGINE
Remove the cable from the retaining bracket. Grasp
the terminal as close as possible to the spark plug.
Rotate the cover (boot) slightly and pull straight back.
Do not use pliers and do not pull the cable at an
angle. Doing so will damage the insulation, cable
terminal or the spark plug insulator. Wipe spark
plug insulator clean before installing cable and
cover.

SPARK PLUG CABLE SERVICE—3.5L ENGINE
The cables insulate the spark plugs and seal the top
of the spark plug tube. A grooved tray routes the
cables from the coil to each cylinder. The cables for
the even number cylinders run along the bottom of
the tray (Fig. 5). Cables for the odd number cylinders
run along the top of the tray. Access the cables
through the openings between the runners of the
intake manifold plenum.

CAUTION: When routing cables under the fuel rail on
the left side of the engine during the cable removal or
installation process, do not pry up on the fuel rail
because permanent damage may occur to the rail. This
damage could result in a fuel leakage condition. Suffi-
cient clearance exists between the fuel rail and cam
sensor for cable routing without moving the fuel rail.
To remove the cables, lightly grasp the top of the
cable with pliers. Rotate the cable slightly and pull
straight up. To replace the cables, disconnect the
cable from the ignition coil. Remove the cable from
the tray and route the coil end under the center of the
intake manifold plenum.
To install the cables, run the coil end under the
plenum and through the cable tray. Route the cables
for the left side of the engine under the front of the
fuel rail and then down the side of the rail (Fig. 6).
Connect the cable to the coil. Slide the insulator into
the tubes and over the spark plug. Ensure the insula-
tor fully seats to the top of the spark plug tube.
