An Engine Coolant Temperature Switch is designed to detect and change the fluctuations in coolant temperature and relay this information to the engine control unit and temperature gauge. When temperatures rise above optimal levels, the switch triggers the cooling system, activating components such as the radiator fan and coolant circulation pump to dissipate excess heat and maintain safe operating conditions for the engine.

Attributes:
• Monitors coolant temperature accurately.
• Provides real-time data to the engine control unit.
• Resistant to high temperatures.

Applications:
An Engine Coolant Temperature Switch is positioned in the engine block, where it directly monitors coolant temperature and safeguards engine operation by activating the cooling system when temperatures rise beyond optimal levels.
