What components are inside the front hood of a car?

Some cars have front-mounted engines, while others have rear-mounted engines. The front hood contains: the engine, radiator, antifreeze, and electrical circuits. Below is a partial introduction about the hood: 1. Main requirements: heat insulation, sound insulation, lightweight, and strong rigidity. 2. Structure: It is in the form of a skeleton, composed of an outer panel and an inner panel, with heat insulation material sandwiched in between. The inner panel serves to enhance rigidity. 3. Function: Made from rubber foam and aluminum foil materials, it reduces engine noise while isolating the heat generated during engine operation, effectively protecting the paint surface on the hood and preventing aging.

I just started driving not long ago, and I was a little nervous the first time I opened the hood. The densely packed components inside were really overwhelming. The main parts include the engine, which is the core power source of the vehicle; the battery is right next to it, used for starting and power supply; there's also the radiator, which contains coolant to help regulate temperature and prevent overheating; the air filter isn't hard to locate either, as it keeps the intake air clean. Additionally, the brake fluid reservoir and power steering fluid reservoir are common—I need to check their levels regularly and see if the color is normal. If you're a beginner like me, when exploring under the hood, you might as well start with the simpler parts, like using the dipstick to measure the engine oil level. This can prevent major issues and save you from repair troubles.

I often tinker with my car and am quite familiar with the components under the hood. The engine is the star—without it, nothing moves; the battery is on one side of the front, responsible for ignition and the power supply system. The cooling system includes the radiator and fan—remember to check the fan belt regularly for wear. The brake fluid reservoir and power steering fluid reservoir are also crucial—low fluid levels can affect braking performance. The air filter should be replaced every six months, as excessive dust can increase fuel consumption. For maintenance, I make it a habit to pop the hood every month to ensure all wiring connections are secure. This helps spot potential issues early, like leaks or looseness—safe driving relies on these details.

From a functional perspective, the engine under the hood provides power; the battery starts the vehicle; the radiator cools the system; the air filter cleans incoming air; brake fluid ensures responsive braking; power steering fluid aids smooth steering. These components work in harmony to maintain driving stability.
