Why Does the Temperature Gauge Show Normal When the Thermostat is Damaged?

[Scott]

The reason the temperature gauge shows normal when the thermostat is damaged is that the thermostat protects the coolant temperature from dropping. Below is an introduction to the related content: 1. How the thermostat works: The thermostat automatically adjusts the amount of water entering the radiator based on the coolant temperature, changing the water circulation range to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within the appropriate temperature range. The thermostat must maintain good technical condition; otherwise, it will severely affect the engine's normal operation. 2. The role of the thermostat: It prevents the engine from becoming too cold. After the engine is running normally, during winter driving, without a thermostat, the engine temperature might become too low. The engine needs to temporarily stop the water circulation to ensure the engine temperature does not drop excessively.
