What to Do When the Car Temperature is Too High
2 Answers
Do not turn off the engine immediately when the water temperature is too high. The correct approach is as follows: 1. Let the engine idle in place for a few minutes, adjust the air conditioning to the warm air setting, turn the fan to maximum speed, and open the hood to help the engine dissipate heat. Turn off the engine only after the water temperature drops. 2. After the temperature drops, check whether the coolant level is normal. If the coolant is found to be below the "min" line, it indicates that the engine overheating is caused by low coolant. Reasons for high car temperature: 1. Insufficient coolant: Long-term water circulation during engine operation can cause slow loss of coolant in the engine cooling system, leading to insufficient water in the radiator and easily causing the engine water temperature to rise. 2. Radiator leakage: Broken or improperly connected radiator hoses can cause leakage, which will obstruct water circulation and, in severe cases, cause the engine to "boil over." 3. Cooling fan failure: A damaged cooling fan or a short circuit in the wiring can prevent the fan from working or cause it to rotate slowly, making it impossible to dissipate the engine's heat. 4. Thermostat failure: The thermostat is a device that controls the flow path of the coolant. If it becomes stuck or fails, the engine's large and small circulation will inevitably be affected, and the engine's heat cannot be effectively dissipated.
When the car temperature is high, it refers to the engine coolant temperature gauge soaring or the warning light coming on, which is very dangerous. If the temperature suddenly rises while driving, I must pull over immediately and avoid continuing to drive to prevent further engine damage. After turning off the engine, do not open the hood right away because the inside will be extremely hot and can cause burns. Wait for 10-15 minutes to let it cool down, and turn on the hazard warning lights to alert other vehicles. Then check the coolant reservoir to see if the level is too low—if so, you can temporarily top it up with distilled water or specialized coolant. Common causes include coolant leaks, radiator fan failure, or a broken water pump. For regular maintenance, I change the coolant every two years and clean the radiator to prevent blockages. Safety is the top priority. If the problem occurs frequently, it's best to tow the car to a professional repair shop to check components like the water pump and fan relay.
