Every memorable drive you’ve experienced in your life begins with the successful operation of the starter on your vehicle. The starter on today’s cars, trucks and SUVs is attached in the rear of the motor, where a gear on the starter aligns with the vehicle’s flywheel to begin the ignition process. Once the engine turns over, fuel is introduced to the combustion chamber and is ignited thanks to the ignition system being activated. When this process works correctly, your engine comes to life. However, when the starter begins to wear out or break, it will impact your ability to drive the car.
Over a period of time, the starter motor will eventually runs its course and wear out. The two components inside the starter that commonly fail are the solenoid (which sends an electrical signal to the starter motor to activate) or the starter motor itself. When this occurs, the starter will be rendered useless and needs to be replaced by a certified mechanic.… READ THE REST
When you turn the key in your car’s ignition, the engine turns over and then cranks. However, getting it to crank is actually much more involved than you might think. It requires a flow of air into the engine, which can only be achieved by creating suction (the engine does this when it turns over). If your engine isn’t turning, there’s no air. No air means that fuel can’t combust. The starter motor is responsible for turning the engine over during ignition and allowing everything else to happen.
How your starter works
Your starter is really an electric motor. It engages when you turn the ignition to “run” and turns the engine over allowing it to suck in air. On the engine, a flexplate or flywheel, with a ring gear around the edge, is attached to the end of the crankshaft. On the starter, there’s a gear designed to fit into the grooves of the ring gear (the starter gear is called a pinion gear).… READ THE REST
Knowing how to change a starter motor will help you stretch your car maintenance budget, so you can use that money for other maintenance tasks. Using the correct steps you’ll avoid ending up with an electrical short circuit, damage to the new starter motor or some other components; and, most importantly, you’ll pay attention to key procedures that may apply to your particular vehicle model. But don’t worry, you don’t need to have much experience working on cars. And, on most vehicle models, you can replace a failed starter at home using some common tools you might already have in your toolbox.
So let’s start.
Tools You’ll Need:
- Wrench set
- Floor jack, 2 jack sands, 2 wooden blocks
- Ratchet, extensions and socket set
- Wire brush
- Shop rags
- Degreaser, if necessary
- Torque wrench

Although we take starter motors for granted today, the so-called “self-starter” wasn’t even conceived of until several decades after the arrival of the horseless carriage. Early automobiles were often started with hand cranks, but various automakers utilized everything from springs to gunpowder to start their engines. You’re probably also familiar with the archetypal image of a pioneering aviator spinning the prop of his airplane to get it going, and that’s also an example of a human-powered “starter motor.”
Early Engine Starting Mechanisms
Modern internal combustion engines typically lack the ability to self start, and the engines used in the first automobiles were no different. These internal combustion-powered horseless carriages utilized a number of different starting techniques, including:
- Hand cranks
- Wind up spring devices
- Gunpowder cylinders
Hand Crank Starters
Hand cranks were the most common type of engine starters in the early days of the automobile. They were essentially crank handles that were temporarily coupled with the engine crankshaft.… READ THE REST
A starter motor is a device that is capable of turning over an internal combustion engine until the process of combustion takes over. This is typically accomplished by providing the necessary mechanical energy to rotate the crankshaft for a given number of cycles. While the starter motor is rotating the crankshaft, the engine begins the process of combustion. The starter is then able to disengage once the engine is running under its own power. Most automotive starter motors are electric, but some applications use pneumatic or hydraulic power.
History of the Starter Motor
In the early days of the horseless carriage, automakers utilized a whole range of different engine starting methods. These first engines were relatively simple. They often had only one or two cylinders, didn’t have electrical systems, and didn’t even compress their fuel mixtures. So while the thought of starting your car the same way you start your lawnmower might sounds incredibly strange today, it was an entirely different matter at the turn of the 20th century.… READ THE REST
A starter is an electric motor that turns over or “cranks” the engine to start it. It consists of a powerful DC (Direct Current) electric motor and the starter solenoid that is attached to the motor (see the picture).
The starter motor is powered by the car battery. To turn over the engine the starter motor requires a very high electric current, which means the battery has to have sufficient power.
Starting system problems are common and not all problems are caused by a faulty starter motor. To find the cause of the problem the starting system must be properly tested. read more below.
The starter solenoid works as a powerful electric relay. When activated, it closes the electric circuit and sends the battery power to the starter motor. At the same, the starter solenoid pushes the starter gear forward to mesh it with the engine flywheel (flexplate) ring gear teeth.… READ THE REST
