How Does a Hood Work?

Without the hood, a car’s engine would have no covering. While a car may have different components to it, the hood is very important because it acts as a protective shield to one of the most important parts of the car; the engine. The engine is important because a car is not able to drive without it. This article will examine how the hood of a car works.

The hood covers the engine and when mechanics are repairing the engine, they must remove the hood first. In passenger cars, a concealed latch holds the hood. Some cars have their hood held down by latch pins. Depending on the make of the car, a hood can carry a wiper, hood ornament, hood scoop, and power bulge.

A car hood is made from steel; however, lately, many manufactures have begun using aluminum, fiberglass, dry carbon and carbon fiber to construct hoods.

Each hood consists of a latch, which is a simple mechanism. Although almost all cars manufactured carry a latch, latches are individually designed according to make and model.

Modern cars have their latch started from inside the car’s compartment at the left of the dashboard. Once the driver pulls the hood release handle the hood will open easily.

A cable runs through the dashboard and ends up at the front of the vehicle that will become active when the driver is opening the hood. There is a secondary latch attached to the other end of the cable, which when pulled, will open the hood.

To pull the hood, the driver has to pull the latch an inch or two from its original position. At the front of the vehicle, there is an added latch known as a safety latch and when the driver locates the safety latch, the hood will open. Constant lubrication of these latches will help to keep the car’s hood operating efficiently.

Some vehicles come with a prop rod made in its interior, which is situated on the side rails or front at the bottom. Others have the prop rod underneath the side of the hood.

Because of rust, some latches will tend not to open. Car hoods that cannot open should get immediate attention as this can cause problems when the vehicle overheats. 
Having working knowledge of one’s car hood will make driving and caring for a car more enjoyable. Knowing how the hood on a car works will give the driver the confidence he or she needs when it comes to opening it.
