Turbocharger: Testing and Inspection
Visually inspect the following points of the turbocharger system:
Checking Air Cleaner Element
1.
Check the air filter element to make sure that it is clean. If it is not clean replace it.
Checking For Cracks In Air Inlet System
Air Inlet Leaks
2.
Check that there are no cracks, rips, cuts, or holes in the air inlet hoses. If there are any openings in the inlet hoses after the air cleaner element,
debris can be sucked into the turbo and cause damage both to the engine and the turbocharger. If there are any leaks in the inlet hose, replace it.
