(4) While supporting the starter motor with one hand, use the other hand to remove the screw and washer that secures the upper mounting flange of the starter motor to the automatic transmission torque converter housing.

(5) Slide the automatic transmission cooler tube bracket forward on the tubes far enough for the starter motor mounting flange to be removed from the lower mounting stud.

(6) Lower the starter motor from the front of the automatic transmission torque converter housing far enough to access and remove the nut that secures the battery positive cable eyelet terminal to the starter solenoid B(+) terminal stud. Always support the starter motor during this process. Do not let the starter motor hang from the wire harness.

(7) Remove the battery positive cable eyelet terminal from the solenoid B(+) terminal stud. Always support the starter motor during this process. Do not let the starter motor hang from the wire harness.

(8) Disconnect the battery positive cable solenoid terminal wire harness connector from the connector receptacle on the starter solenoid. Always support the starter motor during this process. Do not let the starter motor hang from the wire harness.

(9) Remove the starter motor from the automatic transmission torque converter housing.

4.7L ENGINE

(1) Disconnect and isolate the battery negative cable.

(2) Raise and support the vehicle.

(3) Remove the screw and washer (rearward facing) that secures the lower mounting flange of the starter motor to the automatic transmission torque converter housing (Fig. 11).

(8) Remove the starter motor from the automatic transmission torque converter housing.

INSTALLATION

ALL 5.2L AND 5.9L ENGINE

(1) Position the starter motor to the automatic transmission torque converter housing.

(2) Reconnect the battery positive cable solenoid terminal wire harness connector to the connector receptacle on the starter solenoid. Always support the starter motor during this process. Do not let the starter motor hang from the wire harness.

(3) Install the battery positive cable eyelet terminal onto the solenoid B(+) terminal stud. Always support the starter motor during this process. Do not let the starter motor hang from the wire harness.

(4) Install and tighten the nut that secures the battery positive cable eyelet terminal to the starter solenoid B(+) terminal stud. Tighten the nut to 13.6 N*m (120 in. lbs.). Always support the starter motor during this process. Do not let the starter motor hang from the wire harness.

(5) Position the hole in the starter motor lower mounting flange over the stud on the automatic transmission torque converter housing.

(6) Slide the automatic transmission cooler tube bracket rearward on the tubes and into position over the starter motor upper mounting flange.

(7) Loosely install the screw and washer unit that secures the starter motor upper mounting flange to the automatic transmission torque converter housing.

(8) Loosely install the lock washer and nut that secures the starter motor lower mounting flange to the stud on the automatic transmission torque converter housing.

(9) Tighten the screw and washer unit and the nut that secure the starter motor mounting flange to the automatic transmission torque converter housing.

Tighten the screw and the nut to 67.8 N*m (50 ft.

lbs.).

(10) Lower the vehicle.

(11) Reconnect the battery negative cable.
