The considerations below apply generally when replacing any type of turbocharger, specifically the turbo mentioned above. When a turbocharger fails, it releases, more or less depending on the type of failure, a trail of debris that lodges in unimaginable and remote places. This debris is released the next time the engine is started after installing the new turbocharger. Therefore, it is essential to perform extraordinary maintenance and thoroughly clean and/or replace various engine components, such as:

• High-pressure EGR system (Manifold Exit Gas) and Low-pressure EGR system (DPF Exit Gas)    

• Intake system (manifold, bellows, throttle body, etc.)
• Intercooler and related hoses
• Exhaust system (DPF, catalytic converters, manifolds, etc.)
• Air filter and its compartment
• All air lines on the engine

  Pay particular attention to debris that can be drawn into the engine’s combustion chamber and cannot be removed with normal cleaning. Therefore, make sure it is completely expelled before installing the turbo. If this debris is not completely removed, it will be expelled from the exhaust, impacting the crankshaft wheel and the variable geometry, causing irreversible damage to the turbo as shown in the photos below.
