Turbocharger installation checklist

Before Installation

Diagnose and solve the reason for the failure of the old turbocharger (possibly a fault on or around engine)
Compare turbocharger model number with the engine specifications and the turbocharger manufacturer’s model number
Check for proper engine cooling
Check oil supply, make sure oil return from the turbocharger to the crankcase is clear
Check intake, charge air and exhaust area for functional capability
Clean out any contamination by foreign bodies or fluids and solve why they were present
Clean any undamaged air supply hoses and pipes
In the case of liquid-cooled turbochargers: check for adequate coolant flow
Check whether an adjustment of the housing position is necessary
Torque fasteners as specified by the engine and vehicle manufacturer
Make sure the flanges and threads are free of damage, debris, and wear
Use only brand new gaskets and seals
Change engine oil and filter as specified by the engine and vehicle manufacturer

Fill the turbocharger with new engine oil through the oil inlet hole before securing the oil supply line, while slightly turning the rotor manually
Pay attention to correct handling
Idle for approximately 120 seconds after engine is running
During idling, check all connections (air, exhaust, water, and oil) for firm seating, tightness, and free of leaks; gas-tightness should be checked with soapy water if necessary
Monitor oil pressure
After 20 operating hours or 650 miles, check all relevant connections again for firm seating, tightness, and free of leaks.

Only skilled personnel should install the turbocharger
Incorrect installation, use, and modifications can cause damage to the turbocharger and engine
Follow the manufacturer’s specifications and installation instructions
No liability for material defects if the turbocharger doesn’t comply with engine specifications or instructions aren’t followed
Report any visible faults immediately
