These engines are flushed with the mixture of ethylene glycol and vapor corrosion inhibitor (VCI) after the factory test.The engines are equipped with aftercoolers that are prone to freezing during shipment due to the design. The aftercoolers have a small area in the bottom that cannot be completely drained after the factory test. The aftercooler could freeze during shipment of the engine or during storage of the engine. This can cause the cooling fins of the aftercooler cores to fail.Engines that are equipped with the following aftercoolers are now flushed with the mixture:
4P-8882 Aftercooler Gp
4P-8950 Aftercooler Gp
115-1577 Aftercooler Gp
121-7545 Aftercooler Gp The new process is effective with the engine serial numbers that are listed in Table 1.
