(4) While supporting starter motor, remove bolt
and washer (rearward facing) securing starter motor
to the transmission housing.
(5) Lower starter motor from front of transmission
housing far enough to access and remove nut secur-
ing battery positive cable eyelet terminal to the
starter solenoid B(+) terminal stud. Always support
starter motor during this process. Do not let starter
motor hang from wire harness.
(6) Remove battery cable eyelet terminal from sole-
noid B(+) terminal stud.
(7) Disconnect battery cable solenoid terminal wire
harness connector from receptacle on starter sole-
noid.
(8) Remove starter motor from transmission hous-
ing.
INSTALLATION

(2) Connect battery cable solenoid terminal wire
harness connector to connector receptacle on starter
solenoid. Always support starter motor during this
process. Do not let starter motor hang from wire har-
ness.
(3) Install battery cable eyelet terminal onto sole-
noid B(+) terminal stud.
(4) Install and tighten nut securing battery cable
eyelet terminal to starter solenoid B(+) terminal
stud. Tighten nut to 13.6 N·m (120 in. lbs.).
(5) Position starter motor and install bolts/wash-
ers. Tighten bolts to 54.2 N·m (40 ft. lbs.).
(6) Lower vehicle.
(7) Connect negative battery cable.
All 3.9L/5.9L, or 4.7L With Manual Trans.
(1) Position starter motor to transmission housing.
(2) Connect battery cable solenoid terminal wire
harness connector to connector receptacle on starter
solenoid. Always support the starter motor during
this process. Do not let the starter motor hang from
the wire harness.
(3) Install battery cable eyelet terminal onto sole-
noid B(+) terminal stud.
(4) Install and tighten nut securing battery cable
eyelet terminal to starter solenoid B(+) terminal
stud. Tighten nut to 13.6 N·m (120 in. lbs.).
(5) Position starter motor over stud on transmis-
sion housing.
(6) If equipped with automatic transmission, slide
automatic transmission cooler tube bracket rearward
on tubes and into position over starter motor flange.
(7) Loosely install the washers, bolt, and nut to
starter. Tighten bolt and nut to 67.8 N·m (50 ft. lbs.).
(8) Lower vehicle.
(9) Connect negative battery cable.

harness connector to connector receptacle on starter
solenoid. Always support the starter motor during
this process. Do not let the starter motor hang from
the wire harness.
(3) Install battery cable eyelet terminal onto sole-
noid B(+) terminal stud.
(4) Install and tighten nut securing battery cable
eyelet terminal to starter solenoid B(+) terminal
stud. Tighten nut to 13.6 N·m (120 in. lbs.).
(5) Position starter motor to transmission housing
and loosely install two bolts/washers.
(6) Tighten bolts to 67.8 N·m (50 ft. lbs.).
(7) Lower vehicle.
(8) Connect negative battery cable.

STARTER MOTOR RELAY

DESCRIPTION
The starter relay is an electromechanical device
that switches battery current to the pull-in coil of the
starter solenoid when ignition switch is turned to
Start position. The starter relay is located in the
Power Distribution Center (PDC) in the engine com-
partment. See PDC cover for relay identification and
location.
The starter relay is a International Standards
Organization (ISO) relay. Relays conforming to ISO
specifications have common physical dimensions, cur-
rent capacities, terminal patterns, and terminal func-
tions.
The starter relay cannot be repaired or adjusted
and, if faulty or damaged, it must be replaced.
OPERATION
The ISO relay consists of an electromagnetic coil, a
resistor or diode, and three (two fixed and one mov-
able) electrical contacts. The movable (common feed)
relay contact is held against one of the fixed contacts
(normally closed) by spring pressure. When electro-
magnetic coil is energized, it draws the movable con-
tact away from normally closed fixed contact, and
holds it against the other (normally open) fixed con-
tact.
When electromagnetic coil is de-energized, spring
pressure returns movable contact to normally closed
position. The resistor or diode is connected in parallel
with electromagnetic coil within relay, and helps to
dissipate voltage spikes produced when coil is de-en-
ergized.
