What is the normal temperature for a car's temperature gauge?
1 Answers
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.
