What is the normal value of a car's water temperature gauge?
2 Answers
An automobile's water temperature of 90 degrees is considered normal. The following are the causes of excessively high car water temperature: 1. Insufficient coolant: Coolant leakage or a lack of coolant can cause the engine's water temperature to rise. In this case, the coolant level should be checked. If it is low, first add coolant to the appropriate level, then check the level again after a few days to see if it has dropped significantly. If it has, the source of the leak must be found. 2. Cooling fan malfunction: A faulty cooling fan prevents the heat generated during high-speed operation from being effectively transferred to the antifreeze, affecting heat dissipation. This can lead to an increase in the antifreeze's temperature, causing issues such as overheating.
I've been driving for years, and the coolant temperature gauge is something you really need to pay attention to. Under normal driving conditions, the temperature should stabilize around 90 degrees Celsius. If it gets too high, it's dangerous—like when the needle hits the red zone, which could mean a clogged radiator or a broken fan. In that case, you should pull over immediately to let it cool down. On the other hand, if it's too low, especially when starting the engine in winter, it increases engine wear and fuel consumption until it warms up to the normal range. I recommend checking the dashboard regularly, especially before long trips, to ensure the coolant level is adequate and its color looks normal. Adding a bit of water is fine, but make sure it's pure, otherwise it might freeze or lower the boiling point. If the temperature gauge acts up, don't panic—find a safe spot to pull over, do a quick visual check, and if necessary, head to a repair shop to inspect the thermostat or water pump. Staying vigilant can save you a lot of trouble down the road.
