What to Do When the Dashboard Shows High Temperature Warning?
2 Answers
When this warning appears, it indicates a fault in the cooling system, usually caused by a lack of coolant. It is necessary to stop the vehicle promptly and check the coolant. Below is the relevant information: 1. Water Temperature Warning Light: The water temperature warning light is represented by a thermometer-like icon on the vehicle's computer panel. 2. Coolant: Coolant, also known as antifreeze coolant, is designed to prevent freezing. It prevents the coolant from freezing in cold weather, which could damage the radiator and engine block. Coolant is not just for winter use; it should be used year-round. As part of regular vehicle maintenance, the engine coolant should be replaced every year.
A few days ago, while I was driving, the dashboard suddenly lit up with a high-temperature warning, which was quite alarming. Immediately pull over safely to the right and turn off the engine—don’t impulsively open the radiator cap, as hot steam can cause serious burns. Wait patiently for at least 30 minutes, and only open the hood when it’s cool enough to touch, then check the coolant reservoir. If the fluid level is low, top it up with distilled water or antifreeze as an emergency measure. Frequent overheating issues could be caused by a failed fan, a leaking water pump, or clogged hoses—take your car to a professional repair shop for a thorough diagnosis. Prevention is better than cure: inspect the cooling system every six months, clean the radiator of dust, and ensure the fan is functioning properly. During the hot summer months, avoid long continuous drives; let the engine cool down during breaks—these small habits can help prevent breakdowns on the road.
