How Long Should a Car Rest After Driving in Summer?
1 Answers
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.
