Car hood (engine compartment cover, hood) is the external part of a car that is located above the engine and other important parts in the engine compartment.
According to research by the International Automobile Manufacturers Association (OICA), the hood can help protect the engine from 80% of environmental damage such as dirt, rain, or snow.
This is the part that helps protect the engine; usually made from lightweight, durable materials such as steel, aluminum or composite. With a sophisticated design that matches the style of the car, the hood has superior load-bearing capacity, helping to protect internal components from environmental impacts and collisions.
The steps to properly open the hood include: pulling the main latch in the cabin, opening the secondary latch under the hood, holding the hood open with the strut, and finally closing the hood after completing the job.
When opening, use a prop to hold the hood, do not touch the hot engine, check that the hood is tightly closed, and do it in a wide open area to ensure safety. If the car hood is stuck, you can try to open it by hand, check and remove the cable, or recheck the hood locking system.
Let's learn in detail about the features, steps to open the hood and how to handle problems that may occur with the car's hood to ensure safety when using.
Car hoods protect the engine and are made from lightweight, sturdy materials such as steel, aluminum, or composite. The product is designed to match the style and appearance of the vehicle; has good load-bearing capacity to protect internal components from environmental impacts and impacts.
The main function of the car hood is to protect the internal components of the engine compartment from external environmental factors such as dust, rainwater, or foreign objects. Closing the hood helps maintain the durability and performance of the engine, while preventing damage from external factors.
According to a report by Ford Corporation, keeping the engine compartment clean and free of moisture can increase engine life by up to 30%, while also helping to reduce repair costs related to rainwater entering the engine.
Car hoods are often made from lightweight yet strong materials, such as steel, aluminum, or composites. These materials help reduce the overall weight of the vehicle while still providing durability and impact resistance.
Some high-end cars also use special carbon or aluminum materials to enhance corrosion resistance and reduce weight.
Car manufacturers often design hoods to match the style and design of the car, helping to enhance the aesthetics. Hoods can have many shapes and details such as vents, air intakes, or the company logo, creating a striking appearance for the car.
A study by Automotive News found that 72% of consumers said they felt a distinct difference between vehicle models thanks to the subtle design of the hood.
The car hood is designed to withstand pressure from external impacts, such as light impacts or pressure when the car is moving at high speed. This helps protect important parts in the engine compartment from damage due to collisions.
At the same time, the hood must also withstand harsh weather elements such as rain, sun, or snow without deforming or rusting.
To open the hood of a car, you need to pull the main latch in the cabin, open the secondary latch under the hood, use the strut to hold the hood open, and finally close the hood securely.
According to the International Automobile Manufacturers Association (OICA), the main latch of the hood is usually designed to be located near the driver's left foot area, under the steering wheel.
This latch is usually designed as a cable or a small lever. When you pull the latch, it will activate the primary locking mechanism of the hood, causing the hood to open a small distance. However, the hood is not completely open because the secondary lock is still holding the hood.
After pulling the main latch, the hood will open a small amount. Next, you need to move to the front of the car to find the secondary latch. This latch is usually located just below the edge of the hood, and the way it opens will depend on the design of the car. For some cars, you need to gently press or pull up to open the latch.
When the secondary latch is opened, the hood will open completely and you can easily lift the hood up.
Once the hood is up, you will need to use a metal prop to hold the hood in the open position. This prop is usually stored under the hood or on the side of the vehicle, and is responsible for keeping the hood from falling off during inspection or maintenance.
If your car is a high-end model, instead of metal struts, it may be equipped with hydraulic struts. In this case, you just need to gently lift the hood to the fully open position with your hands and the struts will automatically hold the hood in that position.
After you have completed any inspection or maintenance work, you will need to close the hood. If your vehicle has metal struts, you will first need to return them to their proper position before closing the hood. If your vehicle has hydraulic struts, you will simply need to press down gently on the hood until both locking tabs automatically close.
Be sure to double check to make sure both locks are securely closed to avoid the hood opening while the vehicle is in operation.
Statistics from the Insurance Institute for Highway Safety (IIHS) show that not closing the hood tightly can lead to 12% of accidents involving loss of driver control or visibility, due to the hood popping open while the vehicle is in operation.
When opening the car hood, use the support bar to hold the hood, avoid touching the hot engine, make sure the hood is tightly closed and do it in a spacious area to avoid danger.
Before inspecting the engine or any other part of the front of the car, always use a prop to hold the hood open. This will help prevent the hood from suddenly falling, which could be dangerous.
After the vehicle has been operated or has had an accident, never touch any engine parts directly. At this time, the engine is still very hot and can cause burns or injury.
According to the National Highway Traffic Safety Administration (NHTSA), engine temperatures can reach 200-300 degrees Celsius when the vehicle is just running.
Before operating the vehicle, carefully check that the hood is completely and securely closed. Make sure that nothing is stuck in the hood, to avoid the hood being opened during movement, which can be dangerous for the driver or damage other parts.
Because the hood is large, when opening the hood, please do it in a spacious and airy area to avoid causing injury to the person doing it or those around.
When the car hood is stuck, try opening it manually, checking – removing the cable or checking the hood locking system.
If you can hear the cable pulling sound but the hood won't open, check the cables in the cockpit area to make sure they aren't broken or snagged.
According to AutoWeek Magazine, about 5% of hood jams are caused by broken or damaged cables.
Sometimes the hood can get slightly stuck due to factors like heat or corrosion. You can try gently pulling the hood after pulling the release lever inside the car, gently shaking the hood can help release it.
Alternatively, use a small push stick or flat tool to apply pressure from under the hood, but be careful not to damage the paint or other parts of the car.
If opening the hood fails, the next step is to check the cable system by opening the housing under the dashboard and checking the cable system connecting to the hood release lever. If you find a broken or loose cable, you can try replacing or re-tensioning the cable.
If the cable is stuck or tangled in a hard-to-reach area, you can use pliers or a tool to pull the cable out. However, if you are not comfortable doing this, have a mechanic do it for you to avoid further damage.
Find the locking position on the front of the capo and try to check for any obstructions. You can try pushing gently on the locking area to release it.
If the lock is stuck due to corrosion or dirt, apply a little spray lubricant (like WD-40) to the lock area. Then wait a few minutes and try opening the hood again.
According to NHTSA, about 2% of hood latch failures are due to a jammed locking system due to dirt or corrosion.
***Important Note
If the hood is severely damaged after a collision, it must be replaced to ensure engine protection and driving safety.
To clean the hood, use car wash and a soft cloth to wipe it clean. Avoid using strong detergents, which can damage the paint of the hood.

The hood may open if it is not closed securely or the locking mechanism is not working properly. This could result in loss of visibility for the driver and a potential accident.
The hood can become loose due to impact from a collision or due to wear and tear of the locking parts over time. Periodic inspections can help detect and adjust these parts.
