At what temperature gauge reading should you stop or drive at low speed?

[SanJuniper]

When the temperature gauge reading reaches 100 degrees, you should stop or drive at low speed. Here are the details: 1. Introduction: The car temperature gauge usually has two letters, C and H, or uses white and red zones to indicate. C stands for cold, and H stands for hot. If the temperature gauge approaches the H or the red danger zone, and the temperature warning light comes on in severe cases, it indicates that the engine coolant is too high. 2. How the temperature gauge works: The sensor of the temperature gauge is a thermistor-type sensor. It is fixed to the engine cooling water passage with threads. The thermistor determines the current flowing through the coil winding of the temperature gauge, thereby driving the pointer to swing. In the past, tap water was used as the cooling water for car engines. Now, many car engine cooling systems use special coolant. Therefore, it is also called the coolant temperature gauge.
