1.Turn off the engine (The ignition switch and the engine crankshaft).

2.Confirm and exclude the problem causing the old turbocharger breakdown.

3.Clean or replace the engine’s air filter.

4.Replace the new oil filter and engine oil.

5.Inspection whether the new turbocharger’s compressor wheel and turbine wheel without rubbing against their housings. When rotating the compressor wheel or turbine wheel manually, find the cause and resolve it, if there is any rubbing or scratching.

 

1.Residual oil will be kept in the bottom of intercooler if burning oil occurred on the old turbocharger. Make sure to clean up all the residual oil to avoid burning oil again on the new turbocharger.

2.It may be necessary to inspect/replace the catalyst converter for clogging due to burnt oil, broken turbine shaft or broken turbocharger parts. In some cases a restricted converter will cause high exhaust temperatures and possibly damage the engine and/or the turbocharger.

3.To confirm oil return line on normal conditions, not crimped, not plugged and not restricted. Generally speaking, a new oil supply line is highly recommended to replace the old one. Oil supply line will be restricted by old turbocharger debris or oil coking, which is not chemical decomposition. Oil supply line damaged the previous turbo, it will damage the rebuilt turbo as well.

 

Install the turbine wheel to the engine.Before it without connecting the compressor inlet & oil supply line. Using the new gaskets and O-ring. Secure the nuts/bolts attaching the turbocharger to the exhaust manifold using the manufacturers recommended settings.

1.Pre-lubrication by car manufacturer specified oil. To inject ≥30ml oil into turbocharger oil inlet, at the same time to rotate compressor wheel manually. (The injection recommended by turbocharger/ cartridge manufacturer only for replacement).

2.Commissioning the engine.Sart the engine to idle running for 15-20 seconds to exclude the air in the oil line. And then turn off the engine to connect the oil feed supply line and oil return line which oil can smoothly flow through the turbocharger.

3.Install the air filter. Connect it to the air inlet of the turbocharger.

4.Install the exhaust manifold. Connect one to the gas inlet, the other one to be connected to the gas exhaust of the turbocharger.

5.Install the intercooler (if any) or air feed line. Connect it to the air outlet of turbocharger.

6.If the turbocharger is oil and water cooled model, we need to connect water in line and out line.

7.Commissioning the engine for 3-4 minutes to confirm there is no leaking of oil and air.

8.The turbocharger can be used normally. Please refering to the necessary attention and maintenance of the car manufacturer’s instruction to prolong its life as possible you can.
