Names of car body parts
Understand the parts that make your car work. (brake calipers image by Tom Oliveira from

Knowing every car component can seem like an overwhelming task but is actually easier than many people think. Major car parts can be easier to remember once a person understands how they work. It is important to know car parts so you can explain mechanical problems to experts better -- and know when you are dealing with a scam artist.

The muffler is the most visible part of a car's exhaust system, usually displayed as a metal pipe protruding from the bottom back part of the car. Its main function is to reduce the noise caused by the exhaust system's effort to control and release exhaust gases produced by the car engine.


The car battery is perhaps the most recognised part of a car. Its main function is to supply an engine with the electrical power it needs to start the ignition. Car batteries are usually rechargeable and set at 12 volts.

Timing Belt

The timing belt is a rubber belt that drives an engine's internal components. It is visible on some cars, while hidden in others. Proper maintenance should be practised with a timing belt as a broken belt can incur expensive repair costs. The belt should be replaced every 60,000 miles along with the water pump. Should the belt break, the engine will incur damage, immediately shut down and leave the driver stranded.


The alternator keeps the engine running after the battery has done its initial job of starting the ignition. Its voltage output is usually 13 to 14 volts, so it recharges the battery's 12 voltage capacity. The alternator keeps all electrical components running while the car is on.


Carburettors are no longer used in newer vehicles, but they are still an important component in older cars. Carburettors mix air and fuel at the appropriate levels to burn for combustion. The combustion functions as a type of energy-producing mechanism that causes the car to run.


The radiator helps regulate the temperature of a car to prevent overheating or engine seizure. Car engines can reach high amounts of heat with so many combustion fuels running. A radiator removes the heat from the engine system by passing liquid coolant through it. This liquid absorbs the heat and dissipates it out of the engine.
