GM 10465490 Starter, (Remanufacture)

On some vehicles, it may be necessary to remove the exhaust pipe(s) or frame cross-member to gain access to the starter motor. In extreme cases, it may even be necessary to unbolt the mounts and raise the engine slightly to get the starter out. To begin, detach the cable from the negative terminal of the battery, ensuring that the lockout feature is turned off if applicable. Next, raise the front of the vehicle and support it securely on jackstands, applying the parking brake and blocking the rear wheels. Remove the mounting bolts and detach the starter, taking note of the locations of any spacer shims. Under the vehicle, label and disconnect the wires from the terminals on the starter motor and solenoid. Finally, installation is the reverse of removal.

Disconnect the ground cable from the battery, then raise the vehicle to a satisfactory working height. Disconnect the leads at the starter solenoid, marking each with a coded piece of tape for easy identification upon reassembly. Temporarily replace each of the securing nuts to the terminals, as they have various thread types that could cause damage to the stubs if not properly re-installed. Loosen the starter front bracket nut and remove the two mount bolts. Next, remove the front bracket bolt and rotate the bracket to withdraw the starter by lowering its front end. Installation is a reversal of removal; tighten the mount bolts first to the specified torque, followed by the front bracket bolt and nut. Finally, install each of the wires to the solenoid terminals using your identification coding.

If the starter does not turn the engine when the switch is turned on, ensure that the speed selection lever is in the neutral or parking position if the car has an automated transmission, ensure that the front seats belts are engaged and if the car has a manual transmission ensure the clutch pedal is pressed. Ensure that the battery is fully charged and all cables at the battery and starter solenoid terminal are well fitted. If the engine takes its spin but doesn't crank the motor, the over running clutch of the starter may have slipped and therefore to be removed and dismantled. When the starter fails to turn but there is a loud 'click' noise that comes from the solenoid plunger, then the problem belongs to the main solenoid contacts, or main starter. In the absence of sound from the solenoid plunger, the solenoid may be bad or the circuit may be open. To check the solenoid, put the jumper wire from the battery positive terminal to the terminal on the solenoid connected with the purple wire; if the starter spins, the solenoid is good, the problem lies with the ignition or neutral start switches or their respective wiring. If the above processes do not solve the problem and the starter does not operate, then, it is advisable to consult a professional to have the starter/solenoid assembly removed for testing and servicing. In the case the starter charges the engine slowly, the battery charge should be full and all the connections should be tight, the engine oil should be of the right grade and there should not be any mechanical problems. Let the engine warm up to operating temperature and stop the engine, remove the coil to distributor LT lead or 'BAT' on HEl distributors to prevent firing up while crank. Attach the positive probe of the voltmeter at the starter terminal of the solenoid and the negative probe to a good ground. Turn the ignition switch and read the volts meter the instant the steady figure comes up on the meter without using the starter beyond a half a minute or half a minute maximum. A reading now that is 9 volts and above, and with normal cranking speed also suggests a good battery; when voltage is 9 volts and above though cranking is slow, the motor is bad. If the reading is less than 9 volts and cranking speed is slow, the solenoid contacts could be bad, it's recommended that they should be changed.

Ensure the battery is fully charged.

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.

First, check that the shift lever is in Neutral or Park (for automatic transmission) or that the clutch pedal is depressed (for manual transmission). Then, ensure that the battery is charged and that all cables are securely connected at the battery and starter solenoid terminals.

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.

Before diagnosing starter problems, make sure the battery is fully charged.

It may be necessary to unbolt the mounts and raise the engine slightly.
