GM 19180529 Starter Asm, (Remanufacture) (Pg260D)

But don't just assume that the starter is guilty right away if you are troubleshooting a malfunction in the starting circuit. Instead, begin by inspecting several key components like; clean and securely connected battery cable clamps to battery. Check battery cables for damage and replace any damaged ones. If it fails any tests, evaluate its condition and change it. Inspect starter wiring and connections, and also check the tightness of starter mounting bolts. Examine relevant fuses in engine compartment fuse box, if they're blown, investigate the cause and repair the circuit. Evaluate the ignition switch circuit for correct operation. Verify that the underhood electrical center contains a properly functioning starter relay. Ensure this as well as Park/Neutral position switch functions correctly since these systems are important for applying battery voltage to the starter relay respectively at least during cranking. If no engagement occurs when turning the ignition switch to start then check for battery voltage at the starter solenoid. Attach a 12-volt test light or voltmeter to the starter solenoid terminal and have an assistant turn the ignition switch to start while monitoring the test light or voltmeter. It should burn brightly or show battery voltage there. Absence of voltage indicates checking fuses, ignition switch, starter relay and related wiring in starting system. If voltage is present but starter does not turn over remove starter from engine and bench test it for defects. Slow turning requires checking of cranking voltage at starter using volt meter from battery which should not drop below 8 volts with amperage draw not exceeding 350 amps over a 10-second crank period; anything above that can result in a failure of some elements associated with starting system requiring testing within service department. Finally, if nothing happens when power is applied to a particular device (in our case, the starter) but it is believed to be energized, this means that there are two possible problems with the solenoid or starter. Inspect whether the engine is seized by attempting to rotate the crankshaft pulley. If necessary, apply voltage to a bench mounted starter solenoid using a test battery and observe its operation including the pinion drive extending and rotating. From these observations decide whether the solenoid or starter is bad and if not, what may be wrong within the starter assembly.

First of all, you need to disconnect the starter motor cable from the negative battery terminal; then on V8 models you will have to loosen the right front wheel lug nuts and raise the front part of your car using jackstands. For V6 models remove oil pan skid plate in case it is equipped and on V8 models as well remove right front wheel well splash shield. Remove if applicable a starter motor heat shield respectively and separate starter control cable and battery cable from starter motor solenoid terminals. On V8 models take off transmission cover, finally unscrew the mounting bolts of a starting engine. To install a new starter, just reverse the order of these steps ensuring that bolts are tightened according to specifications for torque.

Remove the starter motor mounting bolts and remove the starter motor.

Disconnect the cable from the negative battery terminal.

When suspecting a malfunction in the starting circuit, it's essential not to immediately attribute it to a faulty starter. Instead, perform a systematic inspection of various components and connections to identify the root cause. This is because several factors other than the starter can contribute to starting issues, and diagnosing the actual problem is crucial.

The initial steps for removing and replacing a starter motor include:Disconnecting the cable from the negative terminal of the battery.Raising the vehicle and securing it on jackstands.

Raise the vehicle and support it securely on jackstands.- Detach any brackets from the rear steering gear crossmember, then remove it or, remove the catalytic converter for clearance as necessary.- Remove the engine splash shield.

When dealing with a starting circuit malfunction, it's crucial not to jump to conclusions about the starter's involvement. Instead, conduct a thorough inspection starting with the battery cable clamps, ensuring they are clean and tightly connected to the battery.

Disconnect the cable from the negative battery terminal.

Remove the right front wheel well splash shield.

Disconnect the cable from the negative battery terminal.

If the starter is receiving voltage but does not activate, the following steps should be taken: 1. Remove and check the starter/solenoid assembly on the bench. 2. Ensure that the engine is not seized. 3. If the solenoid plunger extends and rotates the pinion drive, the starter/solenoid assembly is working properly.

If the starter turns over slowly, the following steps should be taken: 1. Check the starter cranking voltage. 2. Check the current drawn from the battery. 3. If the starter cranking amp values are not within the correct range, replace the starter with a new unit.
