Is it normal for the temperature gauge to exceed halfway?

The temperature gauge exceeding halfway is a normal phenomenon. Reasons for normal temperature: The normal range for a car's temperature gauge is between 2-4 bars, which corresponds to a temperature range of 90-110 degrees Celsius. However, some models have a temperature gauge with only one bar, so as long as the needle is in the middle position, it is considered normal. How to check the temperature: On most car temperature gauges, there are two letters marked 'C' and 'H', or white and red zones to indicate the range. 'C' stands for cold, and 'H' stands for hot. If the needle on the temperature gauge approaches the 'H' or the red danger zone, and in severe cases, the temperature warning light comes on, it means the engine coolant temperature is too high.
I've been driving for over a decade, and the coolant temperature gauge is something you really need to pay attention to. Normally, the middle position on the gauge is around 90 degrees Celsius. Going slightly above halfway might be fine, especially when running the AC or climbing hills in summer. But if the needle surges past two-thirds or approaches the red zone, you must be immediately alert—this usually indicates a cooling system issue. Last year on the highway, I experienced a sudden spike to the red line and discovered I was half a reservoir low on coolant due to a leak. I quickly pulled over, shut off the engine, and called for assistance—otherwise, the engine could have been toast. Make it a habit to glance at the temperature gauge regularly, listen for fan noise in traffic jams, and check coolant levels and color every six months to avoid being caught off guard.
Car owners dread encountering coolant temperature issues the most during repairs. If the needle goes past the midline, it's time to be cautious. The normal operating temperature for vehicles is between 85-95°C; slightly exceeding this range is acceptable. However, if the needle consistently runs high for three consecutive days, it's likely due to a stuck thermostat or a clogged radiator. Last month, an old Passat had this exact problem—the owner kept driving until the cylinder head warped, resulting in an 8,000-yuan repair bill. After parking, it's wise to check the temperature difference between the upper and lower radiator hoses; a significant gap indicates a circulation issue. When washing your car, remember to rinse out willow catkins and insect debris from the radiator fins thoroughly. Never mix tap water with antifreeze, as limescale is the worst enemy of water pumps.
