Garrett Advancing Motion invites you to gain technical knowledge with Installer Connect

With turbochargers becoming the norm on most vehicles, now is the time to be trained on the correct procedures for turbo diagnostics and replacement.
The path to gaining recognition as a Garrett Turbo Installer starts on Garrett’s free training website, ‘Installer Connect.’ The tips from Garrett’s experts will get you on track to achieving the Garrett Advancing Motion recognition. Currently there are four levels of certification with a bonus racing level and a further fifth level to be added.
Each level will give you more in-depth expertise about turbos, from what is a turbo to internal parts and functions and various troubleshooting conditions. You can proceed to the next level after you pass an exam to test your knowledge.
Turbo failure diagnostics you can learn from Installer Connect
Before replacing a turbocharger, it is important to conduct a thorough diagnostic check of the engine systems and find the root cause of the vehicle’s problems.
A lack of power, noisy operation, excessive smoke or oil consumption could result from a faulty fuel injection system, restricted or blocked air filter, a damaged exhaust system or a lubrication problem. Also, check the engine crankcase pressure – a higher than normal reading can be caused by piston bypass or blocked breather system, and this requires your immediate attention.
The preliminary steps before replacing a turbo are as follows:
A. Question the customer on failure symptoms;
B. Check the vehicle intervention and repair history;
C. Run the vehicle to reproduce claim; and
D. Run the diagnostic equipment as recommended by the car manufacturer; this will allow to read the error codes of the Engine Control Unit and indicate in which direction to look for the problem.
If the diagnostic check does not uncover any obvious cause, make sure that an extensive trouble shooting analysis is completed on key areas such as foreign objects, lack of lubrication, oil contamination, over-speeding of the turbo and excessive temperature. This is important because turbo damage can often be a symptom of an underlying problem rather than the cause itself.
Garrett recommends you do not diagnose turbocharger failure by turbo replacement as this can be very costly as the replacement turbocharger could be destroyed in seconds if the root cause is not found and rectified. It says the number one cause of turbo failure on a new or worn turbo is oil contamination.
