Step-By-Step Turbocharger Installation Guide
In order to ensure the Niitsu turbocharger functions properly,
here is a clear and simple guideline prior to turbocharger installation.
Always check, understand and determine why the previous turbocharger fails.
Ensure that the problems have been rectified before fitting a replacement unit.
Carefully inspect and remove any dirt, dust, carbon deposits or other debris from air cleaner duct, exhaust manifold and intercooler.
Particles left in these areas can severely damage the turbocharger immediately on engine start up. Replace air cleaner if necessary.
Always replace old gaskets with new ones.
Thoroughly clean and remove any carbon deposits, sludge or blockages from the oil inlet and oil drain flanges.
Prior to installation of a new turbocharger, perform complete oil change.
Prior to installation of a new turbocharger, perform air filter change.
Install the turbocharger on exhaust manifold flange.
Check for correct fit of turbine inlet gasket for tight seal.
Pre-lube the turbocharger by pouring clean engine oil into the oil feed hole of the turbo.
Slowly rotate the rotor several times by hand to coat the turbocharger bearings with lubrication oil.
Connect oil supply line and air cleaner duct to the turbocharger.
With the fuel shut off to prevent engine start, crank the engine for 10 – 15 seconds to build up oil pressure.
Ensure air cleaner duct, exhaust manifold and oil supply line are securely fastened.
Use soapy water to help identify gas leaks, if any.
Failure to follow these installation instructions will result in premature turbocharger failure and warranty denial.
