🔌 Function

  

The thermostat restricts cooling-water flow during warm-up and opens as engine temperature rises, maintaining stable combustion and operating temperatures.

  

Common signs of failure:

  

• Engine overheats because the thermostat remains closed

• Engine runs excessively cold because the thermostat remains open

• Engine temperature fluctuates during operation

• Salt or corrosion restricts thermostat movement

• Poor warm-up, idle quality or fuel economy
