Description:
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, which controls the flow of coolant between the engine block and the radiator, ensuring that the engine stays within the desired temperature 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.
