At what temperature does the engine coolant temperature warning light come on?

[VonJocelyn]

The temperature gauge ranges from 0-130 degrees Celsius, with the normal temperature being 90 degrees at the center. After the vehicle starts, the coolant temperature rises rapidly. Once the needle reaches the center position, the temperature stabilizes. Generally, it's best to start driving when the temperature reaches the middle position. The warning temperature typically occurs between 115-120 degrees Celsius. Additional information: 1. The car radiator, also known as the heat exchanger, is a key component of the vehicle's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket to circulate, achieving temperature regulation. It is an integral part of the car engine. 2. Working principle: When the engine's coolant temperature is high, the water pump circulates the coolant repeatedly to lower the engine's temperature and protect it. In winter, if the coolant temperature is too low, the circulation stops to prevent the engine from becoming too cold.
