How to install turbocharger

Jul 4, 2018


Pre-installation preparing:

1.Turn off the engine (The ignitionswitch and the engine crankshaft).

2.Confirm and exclude the problemcausing the old turbocharger breakdown.

3.Clean or replace the engine’s airfilter.

4.Replace the new oil filter and engineoil.

5.Inspection whether the newturbocharger’s compressor wheel and turbine wheel without rubbing against theirhousings. When rotating the compressor wheel or turbine wheel manually, findthe cause and resolve it, if there is any rubbing or scratching.


Pre-installation checklist:

1.Residual oil will be kept in thebottom of intercooler if burning oil occurred on the old turbocharger. Makesure to clean up all the residual oil to avoid burning oil again on the newturbocharger.

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

3.To confirm oil return line on normalconditions, not crimped, not plugged and not restricted. Generally speaking, anew oil supply line is highly recommended to replace the old one. Oil supplyline will be restricted by old turbocharger debris or oil coking, which is notchemical decomposition. Oil supply line damaged the previous turbo, it willdamage the rebuilt turbo as well.


Turbocharger installation

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

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

2.Commissioning the engine. Sart theengine 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 returnline which oil can smoothly flow through the turbocharger.

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

4.Install the exhaust manifold. Connectone to the gas inlet, the other one to be connected to the gas exhaust of theturbocharger.

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

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

7.Commissioning the engine for 3-4minutes 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 carmanufacturer’s instruction to prolong its life as possible you can.
