What to Do If the Thermostat Is Broken?

[Candice]

If the thermostat is broken, it simply needs to be replaced. The thermostat is part of the cooling system and is a device that controls the coolant flow between the large and small circulation loops. The thermostat automatically adjusts the amount of water entering the radiator based on the coolant temperature, altering the 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 can severely affect the engine's normal operation. For example, if the main valve of the thermostat opens too late, it can cause the engine to overheat. Conversely, if the main valve opens too early, it prolongs the engine's warm-up time, resulting in the engine running too cold.
