The following points define things more briefly.

Inspect the wires and cables In general, the corrosion around the battery terminals is preventing the electrical flow to different components of the vehicle to start it. If you are experiencing layers of corrosion around the battery terminals, then clean them with baking soda and warm water. The following points define the process elaborately.      

Take a small container and mix 1 tablespoon of baking soda with 8 ounces of warm water. Mix the solution thoroughly.

After that disconnect the battery terminals and apply the solution to the terminals using a soft brush.

Use the solution properly for removing all the dirt and acid from the battery which is commonly responsible for draining the battery power.

For checking the electrolyte level, remove the caps from the battery top and make sure that the electrolyte is reaching the bottom of the filler rings.

If the electrolyte is not at the correct level, then add distilled water for maintaining its level.

Inspect the engine flywheel If the starter motor of the GMC Duramax has any problems, then check the engine flywheel with the starter motor. In general, the flywheel is a large and heavy wheel that is located in between the engine and transmission as well as engages the gears to crank the engine. The below points define the things briefly:  



For inspecting the engine flywheel, first, you have to remove the starter motor and set the transmission to Neutral.

In this process, rotate the crankshaf by turning the center bolt on the crankshaf pulley by using the breaker bar and a socket. Moreover, the pulley is located at the front and bottom of the engine block.

Generally, the pulley is rotating the serpentine belt for running the steering pump, alternator, and other components. According to your vehicle model, remove the wheel for accessing the pulley center bolt.

Make sure that the teeth are running in good condition, otherwise, it will prevent the starter motor from cranking the engine. If necessary, then replace the flywheel as soon as possible.

Inspect the starter motor When the starter motor has any problems, you have to inspect the starter motor by raising the front of the vehicle or by removing the intake manifold. If necessary, then consult with a reputed mechanic for checking the starter motor. In this process, use a jack stand and engage the parking brakes as well as block the wheels for preventing the vehicle from rolling.

If the mounting bolts are loose, then keep the starter drive from engaging the flywheel properly. When it happens, you will hear a grinding noise while firing up the engine, and the gear on the starter clash and flywheel unable to mesh smoothly.

When the mounting bolts are tight, then you have to remove the starter motor from the GMC Duramax and check the gear at the front of the starter for engaging the flywheel to crank the engine.

When it happens, you have to use a screwdriver for rotating the gear in both directions.

If it doesn’t move at all or moves in both directions, then replace the starter motor as soon as possible.

Conclusion When the starter motor of the GMC Duramax has any problems, then consult with a mechanic to fix it immediately. If you are living in Jeffersonville, then connect with a certified mechanic for replacing the starter motor of the Duramax.
