Appropriate cooling system maintenance is very important for this engine. Coolant should be inspected for nitrite levels at each service, and use of an additive, or replacement of coolant, should be done as needed. Deteriorated coolant can lead to EGR cooler and / or engine oil cooler failure. Failure of either can cause coolant loss and overheating, prolonged overheating can cause head gasket failure. White smoke may also be emitted from the tailpipe from the burning of coolant. The cooling system should be thoroughly inspected, and replace the EGR cooler and components as needed. With extended overheating, the head gaskets should be inspected for damage. If the cooling system is especially contaminated with oil, flushing agents and a degreaser like Simple Green may be needed to effectively flush the contaminants.
