What does it mean when a car boils over?
2 Answers
Car boil-over typically refers to a situation where the engine's operating temperature exceeds the normal working temperature range, affecting machine operation and potentially causing damage. Below are relevant explanations about car boil-over: 1. Causes of boil-over: There are many reasons for car boil-over. Besides hot weather, overloaded air conditioning operation and faulty cooling components can also cause boil-over. Conducting a comprehensive inspection of the car's cooling system is the primary method to prevent boil-over. 2. Avoid immediately opening the cap to add water when boil-over occurs: After the radiator water boils, there is internal pressure. If the radiator cap is opened immediately at this time, hot water may spray out, causing burns. Therefore, car owners must avoid opening the cap to add water right after boil-over occurs.
"Car boiling" means the engine is overheating, and the coolant temperature rises to the point of boiling, bubbling and smoking like boiling water. I've driven many long-distance trips and encountered this issue—it's quite frustrating. The main reasons are usually insufficient coolant or problems with the cooling system, such as a non-functioning fan or a clogged radiator. Once, while driving on the highway, my temperature gauge shot up, so I quickly pulled over to avoid potential engine deformation or complete failure. Handling it is simple: safely park and turn off the engine, don’t rush to open the radiator cap to avoid burns, wait for it to cool down before checking fluid levels or adding antifreeze. Regularly inspect the cooling system, and before long summer trips, check the fan and water pump to avoid costly roadside repairs. Developing good habits ensures safety and saves money.
