Starter

Replacement of the v6 Starter motor begins with negative Battery Cable disconnection. Begin by removing the torque converter cover. Start by removing the bat terminal nut from the motor Starter solenoid before taking off the engine harness terminal then the positive cable on the battery. First disconnect the electrical connector from the Starter motor then remove the transmission brace. First remove the Starter from the vehicle by taking off its bolts. Start by placing the Starter motor onto the engine so you can bolt it into position then tighten the bolts to 43 nm (32 lb ft). The installation process begins with reattaching the transmission brace while reconnecting the Starter motor electrical connector and securing the engine harness terminal and positive Battery Cable terminal to the Starter. Make sure to align the positive Battery Cable terminal anti-rotation feature properly. Fasten the Starter solenoid bat terminal nut to 10 nm (89 lb in) torque setting before reinstalling the torque converter covers. Afterward, connect the negative Battery Cable.

Before starting the Starter motor replacement process you must disconnect the negative Battery Cable. Next, remove the Intake Manifold. Start by unscrewing the "bat" terminal nut followed by the "s" terminal nut from the Starter motor. Once completed disconnect the Starter solenoid cable from its position. Begin by removing both Starter motor bolts before completely removing the Starter motor unit. Begin Starter motor installation by fitting the device into its slot in the Starter solenoid retention area while ensuring that the large terminal locator tab is properly located. Tighten all Starter motor bolts to a torque specification of 25 nm (18 lb ft). Connect the Starter solenoid cable to the Starter before you install and tighten the "s" terminal nut to 4 nm (35 lb in) torque then move to the "bat" terminal nut at 10 nm (89 lb in). Reinstall both the Intake Manifold while also reconnecting the negative Battery Cable.

Begin by removing the supercharger assembly before starting to replace the Starter motor (LC3). Begin by taking off both the Starter's battery positive cable and the wire from the s terminal of the Starter. Screw out the bolts securing the Starter motor then extract the device. Begin Starter motor installation by following the fastener notice and carefully positioning the Starter motor. When installing the Starter motor bolts tighten them to meet 30 n.m torque specifications (22 lb ft). Fitting the wire and nut to the s terminal of the Starter requires a tight 4 n.m (35 lb in) torque setting on nut assembly. Secure the Starter terminal with a nut before tightening it to 12 n.m (106 lb in) torque. After finishing with the supercharger assembly placement complete the process by securing the negative Battery Cable.

Disconnect the batter negative cable in order to replace the Starter motor (LC3). Next, remove the supercharger assembly. Next, remove the battery positive cable from the Starter and the wire from the s terminal in the Starter. Remove the bolts of Starter motor and remove the Starter motor. To install, start by installing the Starter motor and make sure to adhere to fastener caution guidelines. Fit the Starter motor bolts and clamp them with 30 nm (22 lb ft). Attach the wire and nut to the s terminal on the Starter to tighten nut to 4 nm (35 lb in). Connect another smaller positive cable to the battery post. This should be the utility cable charged with a normal 12-volt 10-amp battery. Halogen lamps around the buss event drive off the battery roaders system. Connect the battery positive cable and nut to Starter terminal, tightening to the torque of 12 nm (106 lb in). Replace the supercharger assembly and finally reconnect the battery negative cable.

Detach the starter solenoid "S" terminal nut, the engine harness terminal from the starter, and the starter solenoid "BAT" terminal nut, followed by the starter cable terminal from the starter.

Raise and support the vehicle, then remove the transmission brace.

Remove the starter bolts and take out the starter.

Position the starter motor to the engine and install the starter motor bolts, tightening them to 43 N.m (32 lb ft).

Take off the "BAT" terminal nut and the "S" terminal nut from the starter.

Remove the intake manifold.

Tighten it to 10 Nm (89 inch lbs.).

Remove the intake manifold.

Turn the ignition OFF and disconnect the battery negative cable.

Remove the intake manifold.

Reconnect the battery negative cable.

Disconnect the battery positive cable from the starter and the wire from the S terminal on the starter.

Turn OFF the ignition and disconnect the battery negative cable.

Reconnect the battery positive cable to the starter, install the starter terminal nut, and tighten it to 13 Nm (115 lb in).

Disconnect the starter solenoid electrical connector from the starter.

Remove the starter motor bolts and take out the starter motor.

Connect the electrical connector to the starter solenoid and reinstall the left catalytic converter.

Reattach the battery positive cable to the starter and secure the starter terminal nut to a torque of 10 Nm (89 lb in).
