What are the consequences of driving in high temperature?

When the water temperature is too high, you need to stop and check immediately, and you must not continue driving, otherwise it will easily damage the engine and even need overhaul.

The heat dissipation of the car depends on the coolant. Engine combustion generates a lot of heat, which will be transferred to the coolant. The coolant is in a circulating state, and it will emit heat when passing through the water tank. When necessary, the fan will start blowing the water tank to speed up the heat dissipation.

But when the weather is hot in summer, the cooling effect will be greatly reduced. In the cooling system, if a component fails slightly, the water temperature will be too high and the pot will boil.

1, insufficient coolant.

This is the first thing to check and basically the only thing you can check. If there is no coolant in the car on the highway or in a desolate place, it can be temporarily replaced by water. Be careful not to open the water tank cover or kettle cover immediately after parking, because the internal pressure is too high, and it will spray out instantly after opening, which is easy to be burned. When the temperature drops slightly, you can slowly open the lid of the pot.

The water tank is too dirty. The water tank has many holes formed by cooling fins, which are easy to have wool and sludge attached to it, which makes the ventilation worse and the heat dissipation effect worse. If it is in winter, the cooling effect is almost no problem because the ambient temperature is low. But in summer, the ambient temperature is high, the water tank is blocked, and the heat dissipation is not good, which easily leads to high water temperature. This situation can be solved by cleaning the water tank.

There are still some problems that can be understood, because I can't solve them myself, so I need to go to a repair shop for repair, such as temperature controller damage, electronic fan damage, water pump damage, water pipe rupture, waterway blockage and so on. It is necessary to find out the cause of the failure and implement maintenance according to the symptoms.

Extended data:

First look at the water temperature meter. The normal water temperature of most cars shows around 90 degrees Celsius, except for a few cars. If the water temperature meter reaches about 100 degrees, it means that the water temperature is too high, and the water temperature alarm light on the meter will also light up. Although the coolant is not boiled, it can't continue to drive and needs to be checked and repaired.

When the water temperature continues to rise, the pot will boil. The phenomenon of boiling is that a large amount of white water vapor will be emitted, because the coolant will overflow when boiling, and a large amount of water vapor will be generated after overflowing, just like smoking. Don't panic at this time, pull over and check whether it is caused by insufficient coolant. If yes, add it to the normal level. If not, seek tow truck rescue.
