Is it normal for the Mercedes-Benz GLA's water temperature to remain at 90°C?

It is normal for the Mercedes-Benz GLA's water temperature to remain at 90°C. Here are some precautions regarding car water temperature: 1. The optimal temperature range for normal driving is between 70~90℃. The car's water temperature is not necessarily 90 degrees, but rather the engine coolant temperature should not be too low or too high—it needs to stay within a certain range. The normal temperature is indicated by the central position of the gauge at 90℃. 2. The normal operating temperature for an engine is between 80°C and 90°C. Temperatures that are too high or too low can negatively affect the engine's normal operation and performance. Additionally, conventional air cooling is often insufficient to dissipate the heat generated by the engine, which is why water cooling systems are widely used in car engines.
I've been driving for years and repairing various car brands, and it's completely normal for the Mercedes-Benz GLA's water temperature to stabilize at 90 degrees Celsius. That's how Mercedes engines are designed—the thermostat controls the water temperature around 90 degrees, which helps with fuel efficiency and emission reduction. If you notice the gauge consistently at 90 degrees, it indicates the cooling system is working well, with no signs of overheating or undercooling. In daily driving, this stable temperature shows the thermostat, fan, and water pump are functioning properly together. Occasionally, in summer traffic jams, it might slightly fluctuate to 95 degrees but quickly drops back, so no need to worry. However, make sure to regularly check the coolant color and level every six months to avoid leaks causing issues. Long-term neglect of maintenance is what could lead to faults.
