In summer, it is recommended to let the car rest after running for about 4 hours or 250 kilometers. Vehicle Cooling System: The vehicle's cooling relies entirely on the cooling system. When the engine temperature is high, a major circulation cycle is activated. The coolant dissipates heat through the radiator and then flows back into the engine to cool it down. Although high-speed driving generates more heat due to higher engine RPM, increasing the cooling system's workload, the increased airflow through the radiator enhances the coolant's cooling efficiency. In some cases, even the high-speed fan may not need to operate to maintain optimal cooling conditions. This means the heat produced by the engine can be entirely dissipated by the cooling system, preventing the engine from overheating. This can also be observed on the temperature gauge; no matter how long you drive at high speeds, the water temperature does not rise. As long as the water temperature remains normal, it indicates the engine temperature is also within safe limits, allowing for extended driving without issues. Airflow at the Radiator: The airflow around the radiator is substantial, ensuring effective heat dissipation. However, the cooling system operates under continuous major circulation. If there are minor issues with the water pump or excessive scale buildup in the coolant passages, it may impede the smooth flow of coolant. While low-speed driving may not pose cooling problems, high-speed driving with increased heat generation could lead to issues, causing the water temperature to rise.

High temperatures in summer mean more breaks while driving. How often should you take a break? Generally, you should stop every two to three hours for about 15 to 20 minutes. The engine works harder in hot weather, and oil temperatures rise quickly, making it prone to overheating or damage without breaks. Tires running at high speeds continuously can also overheat and blow out. During breaks, let the car cool down, check coolant levels and fan conditions, while the driver gets out to stretch and refresh. Driving long distances without breaks not only damages vehicle parts but also increases fuel consumption and emissions. I think planning your trip and stopping at service areas every two hours is the safest approach, ensuring safety and extending the car's lifespan.

In summer, what I fear most when driving is engine overheating. I once drove continuously for three hours without a break and almost broke down on the road. Since then, I've made it a habit to stop and rest for about 15 minutes every two hours. I park in the shade, turn off the engine, and leave the hood open to let it cool down. I also check the tires to see if they're too hot, avoiding issues from excessive tire pressure. During the break, I take the opportunity to refuel and use the restroom, which also helps me stay more alert. Taking breaks during high-speed, high-temperature driving reduces the likelihood of vehicle malfunctions and makes the ride smoother and more comfortable. This is especially important for long trips—don't push your car too hard for too long, as it can cause damage.

Cars need more rest in summer to protect the engine and tires. Driving at high speeds for just one hour in high temperatures can cause engine oil temperature to skyrocket. I recommend stopping to rest for 15 minutes every one and a half to two hours. This allows the cooling system to recover, preventing overheating, boiling, and oil oxidation, thereby reducing engine wear. Tires experience increased pressure during high-speed driving in hot weather, and resting allows them to cool naturally, preventing blowouts. When parked, check that the fan is working properly to ensure good heat dissipation. More frequent rest stops can significantly reduce maintenance costs and improve the vehicle's durability.

For our family summer trip, I've planned to stop every two hours for a 15-minute break. The kids get restless sitting too long, so it's safer for them to get out and move around. The car also gets a chance to cool down—engine temperatures can get high and lead to malfunctions, so letting it rest helps. Tires heat up significantly during prolonged driving; taking breaks allows the pressure to stabilize, ensuring smoother driving. Choose rest stops at service areas or shaded spots where everyone can stretch and avoid fatigue. This keeps the driver more alert, making the journey smoother and safer. Safety first is always the right approach.
