It opens and closes based on temperature, maintaining optimal operating conditions and preventing overheating or overcooling. Proper thermostat function ensures the engine reaches its ideal temperature quickly and sustains it, which is essential for efficiency and emissions control. High-quality construction allows it to withstand thermal cycling and pressure variations typical in heavy-duty engines. Regular inspection and timely replacement of a faulty thermostat can prevent engine damage, improve fuel economy, and extend engine life. This part is critical for maintaining consistent engine temperature and overall vehicle reliability.
