There are about a thousand and one sounds a car can make when it’s deteriorating toward failure. You’ve got clunks from broken suspension parts, the hiss of a spent radiator, and brop, brop, brop of a flat tire. There are so many that it’s sometimes difficult to discern what’s what. That’s especially true of a bad starter.
A car’s starter is a small electrical device that consists of the motor and a solenoid. When you crank the ignition, the solenoid uses the car’s battery energy and sends it to the electric motor. The motor then pushes a starter gear into the vehicle’s flywheel, and poof! ignition. But when the starter goes bad, you’re stuck.
Diagnosing a bad starter is fairly straightforward, and the sound, when told what to listen for, is easily detected. So, stay with The Drive’s crack informational team as we walk you through the sights and sounds of a bad starter.

Hello, online people!
What Sound Does a Bad Starter Make?
A bad starter’s tell-tale noise is loud clicking. It can either have a fast tempo, click-click-click-click-click-click-click-click or a slower lilt of click, click, click, click. No other part makes these noises when they fail, so if you hear either, you’re likely going to be on the hook for a brand-new starter.
How Do You Know If It’s the Battery or the Starter?
The battery and starter are inextricably linked. Yet, they fail in very different ways. To better diagnose issues with your battery or starter, The Drive has put together a list of the most common symptoms of a bad starter.
The easiest way to diagnose a bad starter is if it starts clicking when you turn the ignition or press the starter button. A bad starter may also continue clicking after the engine turns on, too. It should not attempt to start the engine after it’s already been started.
A second symptom is when the ignition’s Accessory detent doesn’t power your radio, HVAC, and other interior electrics. Or if everything is dim and intermittent.
You may also see smoke coming from underneath your car’s hood. Mechanical parts can experience heat-soak, if they’re repeatedly used and don’t engage properly, and cause enough friction that it starts smoking and could catch fire.
Metal Grinding Noise
Before the starter starts smoking, however, you could hear metal-on-metal grinding coming from underneath the hood as you try to start the ignition.

Everything You’ll Need To Replace Your Starter
We’re not psychic, nor are we snooping through your toolbox or garage, so here’s exactly what you’ll need to get the job done.
Organizing your tools and gear to change your starter so everything is easily reachable will save precious minutes waiting for your handy-dandy child or four-legged helper to bring you the sandpaper or blowtorch. (You still won’t need a blowtorch for this job. Please don’t have your kid hand you a blowtorch—Ed.)
You’ll also need a flat workspace, such as a garage floor, driveway, or street parking. Check your local laws to make sure you’re not violating any codes when using the street because we aren’t getting your ride out of the clink.

You’ve got questions, The Drive’s informational team has answers!
How Do You Test a Starter?
One of the easiest ways to test a starter is to turn the starter’s pinion stub. Locate the starter, a large cylindrical part on the side of the engine. Find a small square stub on the outside, and, use a wrench to turn it. If it turns freely, remove the wrench and try starting the car again.
What Causes a Bad Starter?
A bad starter could be caused by oil, dirt, and debris getting into the starter, along with loose connections, battery corrosion, and damaged parts. Age can also play a factor.
