PROBLEM
The exhaust manifold on the C9.3 Industrial Engines listed may contain metallic debris that can eventually fail the cooler, causing coolant to enter the engine. This debris is introduced from the exhaust manifold and was not properly cleaned out during the manufacturing process. Also, the outlet check valves on the common rail fuel pump also need replaced. The current outlet check valves can wear prematurely causing E499 diagnostic code and engine derate.
