ME220538
Thermostat
Mitsubishi FUSO®

A thermostat is a component in a truck's engine cooling system that regulates the flow of coolant to maintain optimal engine temperature. The ME220538 model is specifically designed for use in certain truck models and is responsible for controlling the opening and closing of the engine's coolant circulation valve. When the engine is cold, the thermostat remains closed, preventing coolant from circulating through the engine. As the engine warms up, the thermostat gradually opens, allowing coolant to flow through and cool the engine. This process helps to prevent overheating and ensures that the engine operates at its most efficient temperature range.
