List of Car Parts Must Know Before You Drive

Auto part list, automobile part names, automobiles, automotive, inside, 

Automobiles are complex machines. Modern cars are more complex. If you won a car, necessarily you need to keep some idea of the basic but important parts and their functions. 

Hopefully, this list of automobile parts will help you when you need to repair or replace any of them and how much you’ll cost for different parts too.

Auxiliary Electrical System and Electronic Parts

1. Starting system

The heart of the electrical system is your car's starting system. When you insert the key through the ignitor switch, a little amount of current passes from the battery to the neutral safety switch.

The starter motor helps create a sanction to draw a fuel-air mixture. This mixture is ignited by a spark made by the ignition system.

When all of these happen at the perfect time, the engine starts.

2. Ignition system

Ignition switch distributes current where needed. 5 switch positions are used in the ignition system.

When the key position is locked, all the circuits are open and no current is supplied and when the position is off, you can turn the steering wheel, all circuits are open, and you can't extract the key.

In the 'run' position, only the starter circuit is open. In the start position, the power is supplied to the ignition circuit and starter motor.

Play the radio even if your engine isn't running in the accessory position.

3. Audio/video devices

For in-car entertainment, audio and video devices are installed. 

The audio system includes receivers, amplifiers, subwoofers, and speakers.

Receivers are a vital part of your sound system because they have an impact on the rest of the system.

Improve the power and sound quality with an external amplifier. You can replace your car's older speakers and add subwoofers if needed.

High quality and budget-friendly audio system for your car may cost you $400-$500. 

The superior audio system may cost around $1000. 

4. Sensors

Modern automobiles include a variety of sensors to ensure you identify and prevent possible issues and operate your car efficiently.

The Mass Air Flow (MAF) sensor calculates the density of air taken by the engine. It ensures the right amount of fuel. 

Failure of this sensor may cost you higher fuel than necessary.

5. Lighting and signaling system

The lighting and signaling devices are integrated into the rear, front, and sides to a car. Various lights ensure the size, position, and the presence of your vehicle. They increase visibility.

There are two types of headlamp in a car. The low beam headlamps ensure a proper light distribution without dazzling the other drivers. 

High beam headlamps are suitable when you're driving alone on the road.

Auxiliary lamps include driving lamps and front fog lamps. Cornering lamps are used while changing a lane.

Rear fog lamps are for more visibility from the rear.

6. Gauges and meters

various gauges and meters provide information about the operating status to you. There are two types of gauges; analog and digital.

Speedometers are used to display the speed of your car in Kilometer per hour.

Odometer shows the total distance your car traveled.

The tachometer is for showing the engine speed in RPM. For checking the fuel remaining, fuel gauges are used.

Temperature gauges determine the temperature of the engine coolant. For monitoring battery drawn current, you can use an ammeter. 

The battery voltage can be displayed by a voltmeter. 

7. Cameras

Another essential part of automobiles is the cameras. Cameras can provide first-hand evidence of any car accident and you can report undisciplined drivers.

Cameras have great advantages in parking your car. If you’re on a road trip, you can record the entire trip with dash cams.

Reverse cameras offer a wide rear vision in today's automotive environment to prevent accidents too.

Interior Parts

1. Floor components and parts

Floor components are the carpets and center consoles. Carpets increase the inner beauty of your car. Carpets are made of various materials.

Rubber carpets are less expensive and easy to wash.

You can use fiber carpets for your personal car. 

2. Car seat

Car seats are generally made from durable but inexpensive material. Polyester is the most common material for cat seats.

Bucket seats are separated with a contoured platform and a bench seat is for three people. a variety of adjustments are available for different passengers.

Folding seats offer additional capacity for passengers.

Car body parts

1. Body components

The body components of your car can be seen and publicly known. Body components are bonnet, tires, bumpers, rims, doors, spoilers, Piller, grill, boot, valance, etc.

2. Doors

Cars have four doors consist of the inner and outer door handle, latch, door control, locks.

Handles are used for opening the door. inner one for the passenger inside and the outer one for the passengers.

Door locks provide security.

The fuel tank also has a door to store and supply.

3. Windows

Car windows include glass, window motor, seal, windshield washer, and the window regulator.

You can raise and lower the side windows.

Windscreen, also known as windshield protects from wins, dirt, sun rays, and rain.

The sunroof on top of the car ensures proper ventilation.

Miscellaneous auto parts

1. Air conditioning system (A/C)

The coolant is compressed by the air conditioning system. It lasts longer than the life of your car. 

Leaky seals, the build-up of dirt and debris, and inadequate lubrication are the bad side of this part.

2. Bearings

A wheel bearing is a set of metal balls remains together in a metal ring. A hub is located at the center of wheels where the bearings fit tightly. It helps reduce friction in wheel spinnings.

the wheel may start wobbling if your bearings go bad. More friction can be placed on the wheel. loud noise from your wheel is a common symptom of a bad bearing.

The lifespan of bearings is up to 100000 miles.


The weakest structural component of your car's cooling system is the hoses. They are made of flexible rubbers to absorb the vibration of engine and radiator

Power-train and chassis Parts

1. Engine oil systems

Engine oil system distributes oil to all moving parts and reduces surface frictions. the engine may overheat or seize if the system fails. 

The oil pump pulls oil through a strainer and forced the oil to the bearings and the oil pressure gauge.

The oil passes from the main bearing to the crankshaft and the big-end bearings.

The piston-pin bearings and the cylinder walls are lubricated by the rotating crankshaft. The scraper rings scrap off the extra oil on the piston.

We recommend you the high-quality engine oil to protect automotive engines from being harsh.

2. Engine components and parts

Engines are complicated containing engine block, pistons, cylinder head, valves, camshaft, and crankshaft. 

The engine block is the most important part because magic happens inside it. All the other parts are bolted to the block.

Crankshafts are fit near the engine block. They keep perfect timing on opening and closing the valves.

The flow of fuel, air, and exhaust fumes are controlled by the valves.

an oil pan stores the oil of engine lubrication.

3. Braking system

Brake is needed to slow or stop your car. you'll face a dozen brake issues in different parts. 

Modern cars have four different brakes for each wheel. Drum brakes for the rare wheels, and disk brakes at the front.

Depending on some factors, the average lifespan of a brake pad is between 25000 and 70000 miles.

Brake rotors last up to 70000 miles too. You'll need to change the brake fluid after every 30,000 miles.

4. Fuel supply system

Fuel pumps and fuel injectors are parts of the fuel supply system.

The fuel pump sends fuel from the gas tank to the fuel injector at the proper pressure. It lasts for the car's life (100,000 miles on average). Running the tank low before refilling is a common bad practice.

The fuel injector sprays fuel to the combustion chamber. It may become dirty, clogged, fail to open or close, or leak. 

You won't need to fix it. Cleaning it is a fix. The lifetime of a fuel injector is above 50,000 miles.

5. Suspension and steering systems

Power steering is present in most of the cars. It pumps the fluid to the hydraulic piston. 

The piston is responsible for easier wheel turning. you can check the power steering wheel every month and the color twice a year to ensure if it is working properly. 

Read the owner's manual before replacing the fluid.

6. Engine cooling system

The engine cooling system keeps the engine of your car cool and keeps the temperature warm enough for efficient operation. 

The radiator dissipates heat, and fans provide airflow to keep the radiator cool. 

A water coolant pump circulates coolant through the hoses, engine, and other parts when the particular temperature is reached. 

The cooling system has a role in the cabin's ventilation system as the engine heat may make your car's interior warm.

7. Transmission system

The other name of the transmission system is the gearbox. It transmits the power of torque for movement of the wheels. 

Manual and automatic are the two two transmission systems. You should also replace specific parts of it like the braking system. 

Most often, you have to change the transmission fluid. The max level is 30,000 miles but We suggest you follow the user's guide.

8. Exhaust system

Exhaust system guides the reaction exhaust gases out from an engine or stove. It conveys the burnt gases through exhaust pipes.

The exhaust system includes a resonator to resonate and an echo chamber makes silent all the loud noises coming from the engine.

Technically it is possible to drive your car having a broken exhaust but it needs your rapid attention as it is an important part of your vehicle.


How do I identify car parts?
