🔌 Function

The thermostat regulates engine temperature by restricting or allowing cooling water flow through the engine. Correct thermostat operation helps prevent overcooling, overheating, poor idle quality and inefficient combustion.

Common signs of failure:

• Engine running too cold or too hot

• Overheating alarm

• Poor idle or rough running when cold

• Thermostat stuck open or closed

• Salt, scale or debris build-up around thermostat

• Inconsistent temperature readings

• Reduced cooling-system performance

📦 Condition
