What is the effect of engine high temperature weather?

In hot summer, the temperature seems to be getting higher every day. Driving on a hot street in the scorching sun, the car seems to feel the heat, and there are often unexpected problems, such as sudden breakdown, or a good battery is dead, or you often smell some strange smells, or a good air conditioner suddenly stops cooling. These problems are all because the temperature is too high, and some components in high temperature environment will encounter external high temperature and collide with each other, which is easy to cause problems. To put it bluntly, due to high temperature and strong radiant heat, the power, economy and driving reliability of the car will become worse, and even the normal driving of the car will be affected in serious cases. So finding problems and solving them in time is the key.
