DESCRIPTION
A thermostat is a component in a truck's engine cooling system that regulates the flow of coolant through the engine. The 4065566 part number specifically refers to a thermostat designed for use in Cummins diesel engines. When the engine is cold, the thermostat remains closed, preventing coolant from flowing through the engine until it reaches operating temperature. Once the desired temperature is reached, the thermostat opens and allows coolant to flow freely, helping to maintain proper operating temperature and prevent overheating. A faulty or malfunctioning thermostat can cause erratic engine performance or even damage if left untreated.
