GM 10465462 Starter, (Remanufacture)

If the starter motor does not turn when the switch is operated, first check the shift lever (for automatic transmission) or clutch pedal (for manual transmission). Ensure the battery is charged and all cables are securely connected. If the motor spins but the engine does not crank, the starter motor may need to be replaced. If the solenoid clicks but the motor does not operate, the issue may be with the battery, solenoid contacts, or starter motor. If the solenoid plunger cannot be heard, it may be defective or there may be an open circuit. To check the solenoid, connect a jumper lead between the battery and "S" terminal. If the motor operates, the solenoid is fine. If not, remove the starter/solenoid assembly for testing and repair. If the motor cranks slowly, check the battery and terminal connections. If the engine is partially seized or has the wrong oil, it may crank slowly. To diagnose further, run the engine until normal temperature, then stop and disconnect the coil wire. Connect a voltmeter to the starter motor terminal and ground. Crank the engine and take voltmeter readings. A reading of 9 volts or more at normal cranking speed is normal. If the reading is less than 9 volts and the cranking speed is slow, the solenoid contacts may be burned.

When working under the vehicle, raise it and securely support it on jackstands.

Make sure that the shift lever is in Neutral or Park (automatic transmission) or that the clutch pedal is depressed (manual transmission). Also, check that the battery is charged and that all cables, both at the battery and starter solenoid terminals, are secure.

First, check that the shift lever is in Neutral or Park (for automatic transmission) or that the clutch pedal is depressed (for manual transmission).

The steps for removing the starter in a 4WD vehicle are as follows:Disconnect the negative battery cable.

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 the pinion drive extends but does not rotate, the solenoid is operational but the starter motor is faulty.If there is no movement but a solenoid click, both the solenoid or starter motor are defective.If the solenoid plunger extends and rotates the pinion drive, the starter assembly is functioning correctly.

The steps for removing the starter in a 2WD vehicle are as follows: Disconnect the negative battery cable. Raise the front of the vehicle and support it securely on jack stands. On V6 models, remove the right front wheel for easier access. Remove the front exhaust pipe from the exhaust manifold. On 2.2L engines, take off the brace rod from the front of the engine to the bell housing. On certain models through 1999, remove the support bracket connecting the front of the starter to the block. If equipped, remove the starter heat shield. From underneath the vehicle, disconnect the solenoid wire and battery cable from the terminals on the solenoid. Remove the starter mounting bolts. Take out the starter motor, noting the location of any spacer shim(s), if present.

If the starter motor spins but the engine does not crank, the overrunning clutch in the starter motor may be slipping, and you'll need to replace the motor.

The steps for removing the starter in a 4WD vehicle are as follows: Disconnect the negative battery cable. Raise the front of the vehicle and support it securely on jack stands. Removing the wheel (left wheel on 2.2L models, right wheel on 4.3L V6 models) may facilitate better access. Remove the skid plate. On 2.2L models, take off the front driveshaft. In some early models, you may need to raise the engine/transmission with a floor jack under the transmission and remove the transmission cross member for access to the starter motor bolts. If equipped, remove the starter heat shield. From underneath the vehicle, disconnect the solenoid wire and battery cable from the terminals on the solenoid. Remove the starter mounting bolts. Take out the starter motor, noting the location of any spacer shim(s), if present.

To adjust the shim for the starter, follow these steps: Remove the flywheel housing cover and inspect the flywheel or drive plate for signs of unusual wear. Measure the clearance between the top of the flywheel ring gear tooth and the bottom of the pinion tooth on the starter using a wire-type feeler gauge (round diameter). Normal clearance should be 0.01 to 0.06 inches. If the starter clearance is less than 0.02 inches and the starter whines after engagement, add a 0.04 shim to gain clearance (avoid using more than two shims). If the starter clearance is more than 0.06 inches and the starter whines during engagement, remove a 0.04 shim to gain clearance (avoid removing more than two shims). To install a shim, loosen the inside bolt, remove the outer bolt, and slide the shim between the engine and the starter without removing the starter from the engine block.
