What is the solution for high water temperature during traffic congestion?
2 Answers
When encountering high water temperature during traffic congestion, the solution is to keep the car idling without turning off the engine. Even when arriving home or at the destination, allow the car to idle for 3 to 5 minutes before completely shutting it off. If the temperature remains high after idling for more than 5 minutes, it may indicate a faulty circulation water pump or a blockage in the circulation system pipes, leading to poor circulation. Below is relevant information about high car water temperature: 1. Car cooling systems are divided into two types: water cooling and air cooling (also known as air-cooling). Mid-range and low-end vehicles typically use air cooling, while high-end luxury cars mostly employ water cooling. Water cooling systems can be further categorized into passive water cooling and active electric water pump circulation cooling. Modern vehicles with water cooling systems are generally of the active type. 2. When the car stops, the electric water pump ceases to operate. Once the car starts moving, the electric water pump begins working, facilitating the circulation of cold and hot water to achieve temperature alternation and cooling. Otherwise, the system may experience uneven cooling and heating.
Don't panic when the engine temperature rises in traffic jams. As a frequent long-distance driver, I've encountered this situation multiple times. Overheating usually occurs due to insufficient engine cooling, possibly caused by a stuck fan or low coolant level. Immediately turn on the air conditioning and set it to maximum heat—this transfers heat from the engine to the cabin, effectively lowering the temperature. If possible, pull over safely, turn off the engine, and open the hood to improve airflow for cooling. Then check the coolant reservoir level; if it's below the minimum mark, add water as an emergency measure (though proper coolant is recommended for long-term use). Frequent starts in stop-and-go traffic increase strain, so regular cooling system maintenance—such as inspecting the fan belt and radiator cleanliness—can prevent issues. For safety, avoid driving if the temperature doesn't drop to prevent engine seizure; wait until traffic clears and seek repairs promptly.
