REMOVAL
(1) Disconnect both cables from battery, negative
cable first.
(2) Remove 2 screws holding Power Distribution
Center (PDC) to bracket (Fig. 116).
(3) Remove heat shield from battery (Fig. 117).
(4) Remove nut and clamp holding battery to bat-
tery tray (Fig. 118).
(5) Remove battery from vehicle.(6) Rotate PDC toward center of vehicle to remove

CRANKSHAFT POSITION SENSOR
For removal/installation procedures refer to group
8D - Ignition System, Service Procedures.
CAMSHAFT POSITION SENSOR
For removal/installation procedures refer to group
8D - Ignition System, Service Procedures.
UPSTREAM OXYGEN SENSOR
The oxygen sensor is installed in the exhaust man-
ifold (Fig. 122) or (Fig. 123) or (Fig. 124).
CAUTION: Do not pull on the oxygen sensor wire
when unplugging the electrical connector.
WARNING: THE EXHAUST MANIFOLD AND CATA-
LYTIC CONVERTER MAY BE EXTREMELY HOT. USE
CARE WHEN SERVICING THE OXYGEN SENSOR.
REMOVAL
(1) Raise and support vehicle.
(2) Unplug oxygen sensor electrical connector.
(3) Use a socket such as Snap-On YA8875 or
equivalent to remove sensor.

REMOVAL AND INSTALLATION (Continued)

(4) When the sensor is removed, the exhaust man-
ifold threads must be cleaned with an 18 mm X 1.5 +
6E tap. If using original sensor, coat the threads with
Loctite 771-64 anti-seize compound or equivalent.
INSTALLATION
(1) Reverse removal procedure to install a new
sensor.
New sensors are packaged with compound on the
threads and no additional compound is required. The
sensor must be tightened to 27 N´m (20 ft. lbs.)
torque.
DOWNSTREAM OXYGEN SENSOR
REMOVAL
(1) Raise and support vehicle.
WARNING: THE EXHAUST MANIFOLD MAY BE
EXTREMELY HOT. USE CARE WHEN SERVICING
THE OXYGEN SENSOR.(2) Remove grommet cover to expose connector
(Fig. 125).
(3) Push locking tab back and unplug oxygen sen-
sor electrical connector (Fig. 126).
(4) Use a socket such as Snap-On YA8875 or
equivalent to remove sensor (Fig. 127).

AIR CLEANER ELEMENT
REMOVAL
(1) Remove 2 screws and air inlet resonator (Fig.
128).
(2) Loosen 3 clamps holding air cleaner housing
halves together.
(3) Remove left side of air cleaner housing (Fig.
129).
(4) Remove element from air cleaner housing (Fig.
130).
INSTALLATION
(1) Install a new element in housing.
(2) Position left side of housing.
(3) Snap clamps into place.(4) Install hoses and air inlet resonator.
ENGINE COOLANT TEMPERATURE SENSORÐ2.4L
The coolant sensor threads into the top of the ther-
mostat housing (Fig. 131). New sensors have sealant
applied to the threads.
WARNING: HOT, PRESSURIZED COOLANT CAN
CAUSE INJURY BY SCALDING. COOLING SYSTEM
MUST BE PARTIALLY DRAINED BEFORE REMOV-
ING THE COOLANT TEMPERATURE SENSOR.
