All too often serviceable turbochargers are removed from engines before the cause of the problem has been determined. Always inspect the turbocharger and assess the condition of the turbocharger before removal of the turbocharger from the engine.If the removal of the turbocharger becomes necessary, determine whether the connections were correctly installed. Determine that the connections are without leaks while you are removing the hoses, clamps or connections. Once the removal of the turbocharger has been completed, it may be difficult to determine the conditions that caused the problem.The majority of the problems that occur can be corrected by correct diagnostic procedures. Immediate failures or early failure of a replacement turbocharger may be related to the following issues.
The incomplete correction of the problem that caused the need for the replacement
Problems that are introduced during the replacement of the turbocharger
A faulty turbochargerA turbocharger that has been operated more than fifty hours is not likely to be faulty. Problems with the installation or engine systems can be displayed soon after the replacement of the turbocharger.A turbocharger is not a power source.Turbochargers are an integral component of a complete operating system.Verify that the turbocharger is the correct configuration for the application. Ensure that the assembly and component part numbers are correct. This is particularly important because the process of matching requires slight differences between components. Checks of part numbers are necessary because some of the possible discrepancies will not be apparent to untrained personnel.A turbocharger cannot overcome such objects as malfunctions or deficiencies in the engine fuel system, timing, plugged air cleaners, faulty liners, etc. Replacing a good turbocharger with another turbocharger will not correct basic engine faults.The basic steps to troubleshooting are described below.Visual Checks and Mechanical Checks
Inspect the turbocharger and installation. Listen for unusual mechanical noises. Visually check and test for leaks, blockage, high heat, restrictions or conditions that have allowed wheels to contact the housings. Leaks that are small and insignificant at idle or low power can greatly affect
