Can You Continue Driving If the Car Thermostat Is Broken?

[VonRowan]

You can continue driving if the car thermostat is broken, but it will have certain negative effects on the vehicle, so it is not recommended. The thermostat is a device that controls the coolant's circulation between the large and small loops. If the thermostat is damaged, it can easily cause the engine temperature to become too high or too low. When the engine's coolant temperature drops below the normal range, the lubrication effect deteriorates, leading to increased engine wear and affecting normal operation. If the thermostat fails while driving, the car's coolant temperature can only remain normal at low speeds. If the speed increases slightly, the coolant temperature will drop significantly, preventing the engine from reaching its optimal operating temperature, which results in excessive noise.
