Basic Concepts of a Thermostat

A thermostat is a device that senses the temperature of a system and performs actions to maintain the temperature within a set range. In the context of an engine cooling system, the thermostat controls the flow of coolant between the engine and the radiator. When the engine is cold, the thermostat remains closed, preventing coolant flow and allowing the engine to warm up quickly. As the engine temperature rises, the thermostat opens, allowing coolant to circulate and cool the engine ¹.

Purpose of the Cummins 3423614 Thermostat

The Cummins 3423614 Thermostat regulates engine temperature, ensuring the engine reaches its optimal operating temperature as quickly as possible and maintains this temperature under varying conditions. This regulation is important for efficient combustion, reduced emissions, and the prevention of engine overheating ³.
