The turbocharger is mounted on the exhaust outlet flange of the exhaust manifold. After the engine is started, the exhaust gases flow from the engine through the turbine housing, causing the turbine wheel and shaft to rotate. See Figure
. The gases are discharged into the exhaust system after passing through the turbine housing. The compressor wheel, located in the compressor housing, is mounted on the opposite end of the turbine wheel shaft and rotates with the turbine wheel. The compressor wheel draws in clean air, compresses it, and delivers high pressure air through the intake manifold to the engine cylinders.

Repair or Replacement of Turbocharger
To determine if repair or replacement of the turbocharger is necessary, perform the following procedure. See Figure
Repair or Replacement of Turbocharger Flowchart
Removal of Turbocharger
Remove the turbocharger as follows:
To avoid injury from hot surfaces, allow engine to cool before removing any component. Wear protective gloves.
To avoid injury from contact with rotating parts when an engine is operating with the air inlet piping removed, install an air inlet screen shield over the turbocharger air inlet. The shield prevents contact with rotating parts.
