Cadillac 10465054 Starter (Remanufacture)

Label and disconnect the wires from the terminals on the starter motor and solenoid.

Remove and bench-test the starter motor assembly. Check the solenoid plunger, shift lever, and overrunning clutch for proper operation to identify any defects in the starter motor or solenoid. If the pinion drive extends but doesn't rotate, the solenoid is operational but the starter motor is defective. If there's no movement and the solenoid clicks, either the solenoid or starter motor is defective. If the solenoid plunger extends and rotates the pinion drive, the starter assembly is operating correctly.

When dealing with slow starter cranking, especially in extreme cold conditions, consider ensuring the battery meets the application's requirements, having clean and corrosion-free battery terminals and cables, and warming the battery and engine block if necessary.

Remove the starter motor shield.

During the installation of the starter motor for 4.3L V6 (2018 and later), 4.8L, 5.3L, and 6.0L V8 engines, you should proceed with the installation in reverse order, ensuring that the starter motor mounting bolts are tightened to the specified torque.

If a malfunction occurs in the starting circuit, first check the battery cable clamps for cleanliness and tightness, inspect the battery cables, test the battery's condition, examine the starter motor wiring and connections, ensure the starter motor mounting bolts are tight, verify the fuses in the engine compartment fuse box, check the ignition switch circuit, inspect the starter relay, and test the clutch start switch (manual transmission) or the Park/Neutral position switch (automatic transmission) for proper operation. To check if the starter is receiving voltage, use a test light or voltmeter at the starter solenoid terminal (purple wire) while turning the ignition switch to the start position. If the starter turns over slowly, check the starter cranking voltage and current draw from the battery while the starter is on the engine. The battery must be in good condition, with clean terminals and cables, and the cold-cranking rating should be suitable for the application. In extreme cold temperatures, warm the battery and engine block before testing. If the starter receives voltage but doesn't activate, remove and bench-test the starter motor assembly. Check the solenoid plunger, shift lever, and overrunning clutch for proper operation to identify any defects in the starter motor or solenoid. If the pinion drive extends but doesn't rotate, the solenoid is operational but the starter motor is defective. If there's no movement and the solenoid clicks, either the solenoid or starter motor is defective. If the solenoid plunger extends and rotates the pinion drive, the starter assembly is operating correctly.
