What are my vehicle's main systems?

Posted: October 2021

For your car to run smoothly and safely, its various systems need to be working properly. When you first suspect a problem with any of your vehicle's systems, you'll want to be proactive about getting to the shop. By acting quickly, you'll have the best chance to address the issue before it worsens and becomes more expensive to address. At Freeport Automotive, our local mechanics provide comprehensive mechanical repairs. Here's a brief overview of the main systems in an automobile.


Modern cars and light trucks have four stroke engines, whether they burn gas or diesel. The four strokes are intake, compression, combustion, and exhaust. Important engine components include the block, pistons, camshaft, crankshaft, and valves. Signs of engine trouble include knocking noises, power loss, and an illuminated check engine light.

Braking System

To stay as safe as possible on the road, it's critical that your brakes are working flawlessly. Main braking system components include the rotors, calipers, master brake cylinder, pads, and brake lines.


It's through your car's transmission that power generated by the engine is directed to wheels. With a healthy transmission, the gear ratio between the drive wheels and engine will be properly adjusted to sync up with your car's changes in speed.

Cooling System

To minimize the risk of overheating, it's crucial that your cooling system remains in excellent condition. The main parts of the cooling system include the radiator, water pump, hoses, and thermostat.

Fuel System

A healthy fuel system allows gas to easily move from the tank to the combustion chamber. Important fuel system parts include the fuel pump, fuel filter, and fuel injectors.

Auto Electrical System

Automotive electrical systems serve a variety of purposes, from keeping your tunes blaring to getting your engine to start. While your engine is running, the alternator creates power, which gets stored in your battery.

Exhaust System

A healthy exhaust system will safely route hazardous fumes from your engine to your tailpipe. Main exhaust system parts include the exhaust manifold, catalytic converter, and muffler.
