There are many components that make up your vehicle, and each plays a crucial role in its operation. These parts work together to ensure that you can get from one place to another smoothly. While you may recognize their importance, understanding how they function can be less clear.
Having knowledge of how things work under the hood can help you become a more informed consumer, especially when it comes to vehicle repairs. Being able to engage in meaningful discussions with an automotive technician allows you to understand what’s being done to your car and why.
We’re not suggesting you need to become a master technician! But we are here to guide you through the basic parts of a car, which can assist with troubleshooting problems and help you become a more responsible car owner.

When it comes to understanding the various parts of a car and their functions, starting with the basics is essential. Building a foundational knowledge of key car components will serve you well over time.
It makes sense to begin with the most vital part under the hood: the engine. Most modern vehicles are powered by internal combustion engines, which produce energy by igniting a mixture of air and fuel.
In contrast, electric motors store energy in rechargeable batteries. Electric vehicles tend to accelerate faster than their fuel-powered counterparts. Regardless of whether your car has a traditional combustion engine or an electric motor, it won’t operate without this crucial component!
Your car’s battery plays several key roles, the most important being to provide the power needed to start the vehicle when you turn the ignition. The battery also ensures that other electrical components in your car, such as lights and infotainment systems, function properly.
A dead battery can leave you stranded, waiting for a jump-start. It's wise to have your battery checked if you notice signs like a clicking sound when turning the key or dimming headlights.
The alternator generates electricity to keep your battery charged by converting mechanical energy into electrical energy while the car is running. It maintains the charge of the battery throughout each trip and ensures all electrical components function correctly. Signs of a failing alternator, such as dimming headlights and difficulty starting, often resemble those of a dying battery. Ignoring alternator problems can lead to battery issues and potentially leave you stranded.
Brakes are crucial for slowing down and stopping your vehicle, as well as keeping it stationary when parked. Most cars have either a disc or drum brake system. Disc brake systems include calipers, rotors, and pads, while drum brake systems consist of brake drums and shoes. Components in both systems can wear down over time. Any changes in how your brakes sound or feel should prompt a check-up.
The radiator is a key component of your car’s cooling system, designed to manage the engine's heat. It removes heat from the coolant before it recirculates to cool the engine, preventing overheating and promoting performance and longevity. To maintain the radiator, check coolant levels at least twice a year.
The transmission, or gearbox, transfers the engine’s power to the wheels through various components. Manual transmissions are operated by a gear lever or shifter, while automatics handle gear changes automatically. Regularly changing the transmission fluid according to the manufacturer’s recommendations helps maintain this crucial component and prevent wear.
The shock absorbers are a vital part of the suspension system, ensuring a smooth ride by keeping your tires in contact with the road. They help stabilize the vehicle, making driving safer and more efficient. Worn shocks can cause vibrations, uneven tire wear, and other issues.
The catalytic converter is a key part of the exhaust system that regulates and removes harmful emissions. It converts harmful compounds in exhaust gases into safer substances before they are expelled through the tailpipe. Problems with the catalytic converter can lead to decreased performance and fuel efficiency.
