An Engine Thermostat is a component of an engine's cooling system that regulates the flow of coolant to maintain the engine's operating temperature within an optimal range. It serves as a temperature-sensitive valve that opens or closes based on the coolant temperature.

Attributes:
• It detects the temperature and initiates actions accordingly.
• It helps maintain the engine within an optimal temperature range for efficient combustion
• Provides resistance against corrosion to ensure long-term performance.

Applications:
An Engine Thermostat controls the flow of coolant between the engine block and the radiator, ensuring that the engine stays within the desired temperature range.
