What Are the Causes of a Faulty Thermostat?

Due to prolonged warm-up time, electric flatbed trucks operate at lower water temperatures, causing combustion gases to form acidic substances with the water condensed on the cylinder walls, which corrode the cylinders and lead to thermostat failure. Below is some relevant information about thermostats: 1. Introduction: A thermostat automatically adjusts the amount of water entering the radiator based on the coolant temperature, altering the water circulation range to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within an appropriate temperature range. 2. Working Principle: The most commonly used thermostat is the wax-type thermostat. When the coolant temperature is below the specified value, the refined paraffin inside the thermostat's temperature-sensing body remains in a solid state, and the thermostat valve closes the channel between the engine and the radiator under the action of a spring. The coolant then returns to the engine via the water pump, initiating a small internal circulation within the engine.
