The Detroit Diesel A4722004115 Coolant Thermostat is a factory-spec thermostat for the DD15 engine platform, designed to regulate engine operating temperature by controlling coolant flow. Its aluminum housing and steel tube construction ensure durability under heavy-duty conditions and promote efficient heat transfer. This component maintains optimal engine performance and helps prevent overheating by opening at its engineered temperature point and allowing coolant to circulate through the radiator. Engineered for direct fit on compatible heavy-duty trucks, the A4722004115 restores precise thermal control and system reliability.
