Damage to the thermostat may cause the following faults:
1. Overheating: If the thermostat cannot be opened or closed normally, the flow of coolant and temperature adjustment will be affected. If the thermostat is always closed, the coolant cannot flow through the engine cooling system, causing the engine to overheat. Overheating may lead to serious consequences such as engine damage, cylinder head deformation and seal breakage.
2. Over-cooling: On the contrary, if the thermostat cannot be closed, the coolant will continue to flow, resulting in over-cooling of the engine. Supercooling will affect combustion efficiency, increase fuel consumption and increase the risk of engine wear. In addition, supercooling may also cause the coolant to freeze in the cooling system, resulting in blockage and damage of the cooling system.
3. Unstable temperature: Damage to the thermostat may also lead to unstable coolant temperature. For example, if the thermostat can't maintain a stable open or closed state, the coolant temperature will not be maintained within the ideal working temperature range. This may lead to engine performance degradation, combustion efficiency reduction and unstable working conditions.
4. Coolant leakage: Damage to the thermostat may also lead to coolant leakage. For example, a poor seal of the thermostat or a damaged expansion valve may cause the coolant to leak from the thermostat. Coolant leakage will lead to cooling system pressure drop and cooling effect weakening, which will lead to engine overheating and other cooling system failures.
In a word, the damage of thermostat may lead to engine overheating, supercooling, temperature instability and coolant leakage. These faults may have a negative impact on engine performance, combustion efficiency and normal operation of cooling system. Therefore, it is very important to check and maintain the working state of the thermostat regularly to ensure the normal operation of the cooling system and the reliability of the engine.
