The temperature is high in summer. Does the car need to stop and take a rest after driving for a long time?

As the weather gets hotter and hotter, the issue of car use has become a matter of great concern to everyone. You may have noticed that the weather is hot now. If you take a highway trip and stand near the front of the car, you will obviously feel that the front of the car is very hot. In this case, if you think about it, the engine must be hotter. In fact, this is also a normal situation. When driving at high speed for a long time, the engine speed is so high that it will definitely generate a lot of heat. In this case, can the car withstand it? If the car has been driving on the highway for too long in the summer, should it be stopped appropriately to take a rest? Considering that many car owners are worried about this, let us analyze this issue in detail. Let’s talk about the structural issues of the engine first. No matter what kind of engine it is, whether it is a naturally aspirated engine with a simple structure and strong stability, or a turbocharged engine with a complex structure and a high failure rate, they will not cause problems easily. They have been tested for thousands of hours in harsh environments. In daily driving, both engines are capable and are unlikely to cause problems. Therefore, from the perspective of the engine structure, the possibility of engine problems due to heat in summer is not high.

So is the car’s cooling system unreliable? If a car dissipates heat, it mainly relies on the cooling system. The coolant dissipates heat through the water tank and then flows into the engine to cool the engine. When driving at high speed, the car's speed is relatively high and it generates more heat. At this time, the cooling system has to bear greater pressure, but the heat dissipation effect of the coolant is also good at this time. Even without a high-speed fan, good heat dissipation conditions can be achieved.

Perhaps in the eyes of the car owner, the heat at the front of the car is a sign that the car cannot dissipate heat in time, but in fact, the car's cooling antifreeze circulation pump and other cooling systems are always working. Therefore, even though the reliability of the turbocharged engine is not that good in everyone's opinion, it does not feel as "weak as wind" as imagined. Some car owners may be more careful when driving, so they want to stop and take a rest after driving on the highway. There is indeed no harm in doing this, as it can avoid carbon deposition at high temperatures in the engine oil. But there’s really no need to worry too much about engine problems.

When driving in high temperature conditions, everyone needs to pay attention to the water temperature of the car. If the water temperature is normal, there is no need to worry about the engine overheating. If the water temperature rises, then the engine may overheat at this time. In addition, if you are worried about the car's slow cooling speed, you should regularly check whether the car's coolant is sufficient. Sometimes when a car is used for too long, the engine parts may deteriorate. If the temperature is too high, the car may spontaneously ignite while driving. Therefore, to be on the safe side, the car should be inspected regularly.

Nowadays, there is no need to worry about the quality of cars. Quality problems are extremely rare. There is no need to worry about the engine temperature being too high. As long as it is properly maintained, there will be no abnormalities even if you drive for several hours. There may be cautious friends who will stop to cool down the engine after driving for several hours. This is of course understandable, but there is no great need to do so.

Written at the end:

To be on the safe side, in the case of high temperatures in summer, how long should a car not be driven on the highway for longer? To be on the safe side, it’s best not to exceed three hours in a row. Many friends who have bought a new car take good care of their car. In fact, they only need to maintain the car regularly and develop good car usage habits. Generally speaking, there is no problem in driving under high temperature conditions in summer, and it will not cause engine failure. What do you think about this issue? Do you need to stop and rest while driving in summer?
