The harm of car exposure in summer. How to solve the problem that the car cannot start after being exposed to the sun

When it comes to using cars in the summer, what car owners are most concerned about is definitely car sun protection and cooling. For many friends, this should be a nightmare. High temperature exposure, the temperature inside the car can reach 60 degrees, which can easily make people irritable and angry, and the vehicle performance will decline, and the accident rate will also increase. So the question is, the following is an introduction on how to cool down a car exposed to the sun in summer. If your car is often exposed to the sun, you can try the following method to cool it down.

The dangers of car exposure in summer

Increased formaldehyde

The components of a car contain a large amount of colloid, which is glued together with urea formaldehyde resin. After being exposed to the sun, it may cause a surge in formaldehyde. People sitting in such a car are at great risk of inhaling formaldehyde, which poses a great risk to their health.

Hemorrhoid Attack

Many people get into the car directly from outside. The car seats are extremely hot, and it takes time to turn on the air conditioner to cool down. This is why many people develop abscesses on their buttocks or even hemorrhoids in the summer. Traditional medicine believes that this is caused by the invasion of heat toxins.

Rearview mirror debonding

The temperature inside a car is very high after being exposed to the sun. In order to cool it down quickly, the air conditioning is often lowered to the lowest setting. This will cause the car wall to shrink rapidly, causing the car wall and the exterior to debond. Over time, the adhesion of the rearview mirror will debond.

Hardware aging

The sunlight is strong in summer and the ultraviolet rays are also stronger than in other seasons. If a vehicle is exposed to the sun for a long time, it will easily cause the plastic components of the vehicle to age. The sealing rings of the windows will easily age and crack after being exposed to the sun for a long time, and the sealing of the windows will decrease, making it easy for water seepage and leakage to occur on rainy days.

Flammable and explosive

Long-term exposure of vehicles to the sun may cause spontaneous combustion. With global warming and the increase in the number of cars, spontaneous combustion of cars has become more frequent. With the windows closed, the temperature inside the car is higher than outside the car. It is not difficult to understand why spontaneous combustion occurs. There is also the risk of explosion if there are lighters, gas tanks, etc. in the car.

How to cool down your car in the summer

1. Open the car door to dissipate heat: After the car has been exposed to the sun in the summer, it is best to open the door first to dissipate the heat. This will allow air convection to slowly cool the car down. When the car is not so stuffy, you can close the door and turn on the air conditioner. In the summer, it is best to buy an insulating pad and put it on the seat to avoid heat toxins.

2. Glaze the car: In order to reduce the stuffiness caused by ultraviolet rays, automobile manufacturers have developed a polymer ultraviolet reflective paint care agent. To avoid overheating of the car body in summer, you can brush a layer of care agent on the car surface to reduce the damage of ultraviolet rays to your car.

3. Clean the water tank: Remember to clean the water tank when washing the car. Various impurities are easily attached to the water tank, which is not conducive to the heat dissipation of the engine. Therefore, cleaning the water tank is also one of the ways to help cool the car.

4. Install a sun visor: In summer, the sun will expose the car to the sun, causing the interior of the car to heat up. The sun visor can reflect the sunlight and prevent it from directly exposing the car. The sun visor is usually placed in the front and back of the car. Using the sun visor to block the sun will reduce the temperature of the seats and instruments. It is a good way to cool down.

5. Open the window when parking: The temperature is very high in the summer. If you park your car on the side of the road with the door closed, the temperature inside the car will be hotter than outside when you come back. You can consider leaving a small gap every time you park your car to prevent valuables from being lost. It is recommended to leave a gap of one finger, so that the air inside the car and the air outside can circulate, which can lower the temperature inside the car.

6. Park in the shade: The reason why the car gets very hot is because it is parked in the sun and is exposed to direct sunlight. If conditions permit, it is recommended to park the car in a professional underground garage, under the shade of trees, or other sheltered places. This can fundamentally prevent the car from overheating.

How to solve the problem that the car cannot start after being exposed to the sun

It should be that the gasoline in the oil pipe is gasified by high temperature, forming air blockage. Formaldehyde and ethanol gasoline are most likely to be gasified. Parking in a cool place can solve this problem. Air blockage refers to the oil pipeline being blocked by air generated by high temperature, causing the engine to stall due to lack of oil supply. The solution is to improve ventilation conditions or add a heat insulation gasket (plate) between the oil pipeline and the engine. Separate the heat radiation generated by the engine. Air blockage is the phenomenon that gasoline gasifies and produces bubbles due to high temperature in the oil pipeline. In other words, it is gasoline rather than air bubbles that block the oil path. In severe cases, the car stalls. Pay attention to improving the ventilation conditions of the car engine. The method is to temporarily stop the car and wait for the engine to cool down a little to eliminate it. Air blockage refers to the phenomenon that gasoline vapor generated by gasoline volatilization under high temperature accumulates in the pipeline, affecting the vacuum of the oil pump, resulting in insufficient or interrupted oil supply.

Can I wash my car after it's been exposed to the sun?

It is not recommended to wash the car immediately after it has been exposed to the sun. However, it is okay to wash it once or twice occasionally. Cars are not tofu and are not that fragile.

The reason why it is not recommended to wash the car immediately after it has been exposed to the sun is that the temperature of the front windshield is relatively high at this time. Once it comes into contact with cold water, it is easy to burst due to thermal expansion and contraction.

In addition, after the car paint has been exposed to the sun, it is also not suitable to be washed directly with cold water. The reason is very simple, it is still the principle of thermal expansion and contraction.

If the car paint that has been exposed to the sun is directly washed with cold water, it is easy for the paint to crack.

Professional car washers usually use a car wash gun to spray water into the air in summer to cool the car paint before washing the car.

After the car has been exposed to the sun, you can move it to a cool place for about half an hour to wait for the temperature inside the car to drop. You can also touch the car body or glass with your hands to feel the temperature, which is best when it is close to body temperature.

Don't wash your car too often. It's the same as washing clothes. If you wash clothes too often, they will fade easily. The same is true for car paint.

If you wash your car too frequently, the protective layer on the surface of the paint will be lost, and the aging of the paint will be accelerated without the protective layer.
