The normal temperature for a car's coolant temperature gauge should be around 90℃. This calibration is set during the initial design of the engine, taking into comprehensive consideration factors such as engine material, oil performance, gasoline atomization level, and the impact of temperature on the lifespan of various components. Reasons for the temperature warning light to activate despite normal water temperature include: Insufficient coolant: Owners can check if there are any leaks in the radiator causing low coolant levels. If there are no leaks, coolant can be replenished promptly. If leaks are found, the radiator needs to be replaced. Thermostat malfunction: When the thermostat is damaged, the water hoses do not operate in the normal small and large circulation states, which can also lead to excessively high radiator temperature. Faulty cooling fan: If the car's cooling fan does not rotate, the radiator cannot dissipate heat, naturally causing the coolant temperature to rise and leading to "boiling over." Circulation water pump failure: Common issues with the circulation water pump include cracked impellers or detachment from the pump shaft, preventing the cooling system from circulating properly and resulting in excessively high water temperature.

As a veteran driver with years of experience, I can share some personal observations. The car's temperature gauge should normally display around 90 degrees, which is the ideal operating point for the engine. If it goes above 110 degrees, it may overheat, causing the engine to boil and potentially leading to breakdowns; below 70 degrees indicates insufficient engine warm-up, resulting in shaking and higher fuel consumption. During daily driving, I make it a habit to keep an eye on the gauge, especially during summer road trips or traffic jams when temperatures tend to rise. As long as the needle stays steady between 80-100 degrees, I feel at ease. If you notice any abnormalities, don't push it—pull over immediately to check the coolant level and top it up with antifreeze if needed. A car is like an old companion—regular maintenance of the antifreeze and fan system, along with periodic coolant changes, can prevent 90% of issues. Temperature monitoring is a crucial part of driving safety, and developing a habit of checking before starting the car is both simple and ensures peace of mind.

I've been driving this car for over three years, and the electronic temperature display always fluctuates between 85-95°C, which is the normal range. Modern car designs have optimized the cooling system, and the warning light will only come on when the temperature exceeds 105°C—at that point, you should stop and turn off the engine to avoid severe damage. If the temperature stays too low, around 65°C, the thermostat might be faulty, affecting fuel efficiency. Don’t panic if the temperature rises quickly during daily commutes; the fan will automatically kick in to cool it down. I recommend beginners download a car diagnostic app—it can teach you to quickly identify simple issues like low coolant or aging hoses. Though the temperature gauge seems minor, it’s critical to engine longevity. Never ignore dashboard warnings, and occasionally clean the fan radiator fins during car washes to extend the system’s life. In short, maintaining around 90°C is ideal. Safe driving starts with attention to detail.

When transporting family members, it's essential to monitor the car's temperature at all times. The normal range typically fluctuates around 90 degrees. Exceeding 110 degrees can be dangerous and may lead to radiator rupture, while temperatures below 75 degrees can cause poor engine performance. I usually wait a few minutes after a cold start until the temperature rises above 80 degrees before driving to avoid abnormal wear. Checking the coolant level is crucial – if it's low, top it up immediately to prevent safety issues. Developing a habit of checking the dashboard regularly makes for a worry-free experience.
