The floor thermostat switch, also known as a thermal switch, plays a pivotal role in the electric radiator cooling fan system related to engine cooling. Here’s an overview of its functionality and purpose:

Temperature Monitoring: The floor thermostat switch, positioned on the radiator or engine block, is essentially a temperature-responsive device. Its primary function is to keep track of the coolant’s temperature.

Initiating the Cooling Process: Once the engine temperature attains a specific limit, typically ranging from 180-165 degrees, the floor thermostat switch completes the electrical circuit. This action triggers the activation of the electric radiator cooling fan.

Maintaining Engine Temperature: During periods when the vehicle is stationary or moving at reduced speeds, the electric radiator cooling fan aids in preserving the ideal engine temperature. It accomplishes this by drawing air through the radiator, which facilitates the cooling of the heated coolant circulating within.

Secure Mounting Mechanism: The term ‘threaded’ describes the mounting method of the switch. This implies that the switch body features threads, enabling it to be securely screwed into corresponding threaded holes on the radiator or engine block. This design ensures a stable and leak-proof connection.

In essence, the floor thermostat switch is a temperature-responsive component that initiates the operation of the electric radiator cooling fan, thereby assisting in regulating engine temperature. Its threa
