How Long Should a Car Rest in Summer?
1 Answers
In summer, a car should rest after running for about 4 hours or 250 kilometers. During continuous driving, the temperature of the engine and tires will rise. Generally, after driving for about 4 hours or 250 kilometers, it's advisable to stop and rest for 20 minutes, stretching your limbs. Special attention should be paid to the radiator temperature and tire pressure. Vehicle Cooling System: The vehicle's cooling relies entirely on the cooling system. When the engine temperature is high, it operates in a large cycle where the coolant dissipates heat through the radiator before flowing back into the engine to cool it down. Although high-speed driving increases engine RPM and generates more heat, the cooling system's pressure also rises. However, the airflow through the radiator is greater, enhancing the coolant's heat dissipation efficiency. In some cases, even the high-speed fan may not need to operate to maintain optimal cooling conditions. This means the heat generated by the engine can be fully dissipated by the cooling system without causing overheating. This can also be observed from the coolant temperature gauge—no matter how long you drive at high speeds, the coolant temperature does not rise. As long as the coolant temperature remains normal, the engine temperature is also within safe limits, and prolonged driving won't cause issues. Airflow at the Radiator: The airflow at the radiator is strong, ensuring effective heat dissipation. However, the cooling system operates in a continuous large cycle. If there are minor issues with the water pump or excessive scale buildup in the coolant passages, it may hinder the coolant flow. While this may not cause problems during low-speed driving, high-speed driving with increased heat dissipation demands could lead to rising coolant temperatures.
