A starter motor is an essential component in your vehicle’s engine system, playing a key role in getting your car up and running. It’s responsible for converting electrical energy from the battery into mechanical energy to start the engine. But how long does a starter motor last? Typically, a starter motor can last anywhere from 100,000 to 150,000 miles, depending on various factors such as usage, driving conditions, and maintenance. However, like all mechanical parts, it will eventually wear out and need replacement. This guide will walk you through the symptoms of a bad starter motor, causes, troubleshooting tips, and what to do if your car’s starter motor fails.
When your car refuses to start, the starter motor is often the culprit. Understanding the early signs of a faulty starter motor can save you from being stranded in the middle of nowhere. Here are the top six signs of a bad starter motor.
The starter motor is a small but powerful electric motor that helps start your car’s engine. When you turn the key or press the push-button start, the starter motor kicks in, turning the engine over and setting the vehicle into motion. The starter motor consists of components like the solenoid, armature, and brushes, all of which work together to get the engine running.
In simple terms, without a functional starter motor, your car won’t start.
A failing starter motor will often give off some warning signs before it dies completely. If you notice any of the following, your starter motor might be at risk of failure.
When the starter motor begins to fail, you may hear unusual sounds like a clicking, grinding, or whirring noise. These sounds could indicate that the starter motor is struggling to engage the engine’s flywheel, signaling a need for a replacement. A Generac starter motor makes strange noise, for example, when internal components wear out.
If you turn the key, and the dashboard lights come on, but the engine refuses to crank, this can be a sign of a malfunctioning starter motor. The electrical systems, such as lights and radio, may work because they don’t require as much power as the starter motor.
Perhaps the most apparent sign of a bad starter motor is the engine not cranking at all. When you try to start your car, and you only hear a faint click or no sound at all, your starter motor could be completely dead. This is especially common if oil has soaked the starter motor or if the motor has worn out.
If you notice any of these symptoms, it’s time to schedule an appointment with a professional mechanic. Ignoring these signs could lead to being stranded with a car that won’t start at all.
A burning smell or smoke coming from under the hood can be a sign that the starter motor is overheating. This occurs when the starter motor has been overworked or a short circuit has occurred. Electrical issues in the starter motor can create excessive heat, leading to serious problems.
If you find that oil has leaked onto the starter motor, this can cause the motor to fail prematurely. Oil leaks from other engine components can soak into the starter motor, affecting its ability to function properly. It’s crucial to fix oil leaks to prevent damage to both the starter motor and other components of the engine.
Several factors can contribute to starter motor failure, ranging from electrical issues to mechanical wear. Here are the common causes:
Wear and tear – Like any mechanical part, the starter motor wears down over time, especially in cars with frequent stop-start cycles.
Faulty solenoid – The solenoid is responsible for sending electrical current to the starter motor. When the solenoid fails, the starter motor won’t receive the necessary power to function.
Oil leaks – As mentioned earlier, oil can soak the starter motor, leading to failure.
Electrical issues – Corroded connections, blown fuses, or faulty wiring can prevent the starter motor from getting the power it needs.
If you suspect your starter motor is failing, there are a few steps you can take to diagnose the issue.
Check for loose or corroded wires connected to the starter motor. Inspect the battery terminals as well, as a weak or dead battery can often mimic starter motor problems.
If your starter motor is clicking but not cranking, try tapping the starter motor lightly with a hammer or wrench. This can sometimes help the internal components reconnect, allowing you to start the car temporarily.
If your car is in "Park" and won't start, try shifting the transmission into "Neutral" and then attempt to start it. This trick works because some cars have safety features that prevent them from starting unless they are in the proper gear.
Although it seems unrelated, a low or empty fuel tank can sometimes cause starting issues. Make sure you have enough fuel before ruling out the starter motor as the culprit.
If you’re stuck with a faulty starter motor, there are a few emergency techniques to get your car started.
Ensure the car is on a flat surface and the parking brake is engaged before attempting any troubleshooting.
Locate the starter motor in your vehicle. It's usually found near the engine block. Some cars, especially older models, have small motor hex nut starters that can be difficult to access, so consult your vehicle's manual if necessary.
Try the tapping method as explained earlier. If this doesn’t work, you might need to jump-start the vehicle.
Jump-starting a car can bypass the starter motor if the battery is at fault or temporarily alleviate the problem.
Connect jumper cables to a working car's battery and attempt to start your vehicle.
Once the jumper cables are connected, try to start the car. If the starter motor is the problem, this may not work, but if the battery was just weak, it could do the trick.
If your car starts, immediately drive it to the nearest repair shop to get the starter motor checked or replaced.
How much does a starter motor replacement cost?
The starter motor replacement cost can vary depending on the make and model of your car. On average, it costs between $300 and $500, including labor.
Can I start the motor without a pull cord?
Yes, many modern vehicles and machinery, like a 420cc motor with electric start, don’t require a pull cord to start the engine.
Are automotive starter motor manufacturers in China reliable?
China has become a major hub for automotive starter motor manufacturers and suppliers. The automotive starter motor market is filled with reputable starting motor suppliers from China, offering high-quality products at competitive prices.
In conclusion, recognizing the symptoms of a bad starter motor early on can save you from unexpected breakdowns. Whether you need to troubleshoot or replace your starter motor, it’s always best to consult with a professional mechanic to ensure your car remains in top condition.
