The core definition and function of the thermostat
The thermostat is the "intelligent temperature manager" of the engine cooling system. It automatically adjusts the circulation path of the coolant to ensure that the engine always operates within the optimal temperature range.

The core value and significance of the thermostat
Improving fuel economy: When the engine operates at its optimal temperature, the fuel burns more thoroughly and the fuel consumption is lower.
Reduce engine wear: Avoid keeping the engine running at low temperatures for an extended period to minimize the wear on internal components.
Ensuring engine power: Excessive or insufficient temperature will affect the engine's air intake efficiency and combustion process, resulting in a decrease in power.
Reduce harmful emissions: The engine emits the most pollutants during operation. The thermostat helps the engine quickly enter a state of efficient and clean operation.
Extend engine lifespan: By maintaining a stable operating temperature, it significantly reduces the risk of severe faults such as cylinder seizure and press damage caused by overheating or overcooling.

Common Faults and Consequences
Fault 1: Normally Open State
Problem: The engine heats up slowly, the warm air is not hot, and fuel consumption increases. 
Consequence: If the engine operates for a long time at low temperatures, it will accelerate wear and cause more carbon deposits.

Fault 2: Normally Closed State 
Situation: The pointer of the engine water temperature gauge rapidly enters the red high-temperature zone, even "boiling over". 
Consequence: It is highly likely to cause severe damage to the engine, such as the burnout of the cylinder gasket or deformation of the cylinder block.

Fault 3: Irregular opening and closing / Stuck state 
Phenomenon: The water temperature fluctuates greatly, sometimes high and sometimes low. 
Consequence: The engine operates with instability. If this continues for a long time, it will shorten the engine's lifespan.
