2) Disconnect air intake hose and vacuum hoses. Remove air
hose and air outlet housing. Remove heat protectors. Disconnect
exhaust pipe. Remove power steering oil pump and bracket. Remove
engine hanger bracket. Disconnect oil inlet pipe.
3) Disconnect engine coolant hoses and tubes from
turbocharger. Remove exhaust manifold nuts and bolts. Remove exhaust
manifold and gaskets. Disconnect oil pressure and return pipes. Remove
turbocharger and exhaust manifold assembly. Separate turbocharger from
exhaust manifold.
Removal (3000GT - Front)
1) Disconnect negative battery cable. Drain engine oil and
coolant. Remove radiator. Disconnect exhaust pipe. Remove air intake
hose, air hoses and air pipe. Remove generator and belt. Remove oil
dipstick guide.
2) Remove heat protector. Disconnect front heated oxygen
sensor connector. Remove oil return pipe. Remove turbocharger support
bracket, and remove turbocharger from exhaust manifold.
Removal (3000GT - Rear)
1) Disconnect battery cables, and remove battery. Drain
engine oil and cooling system. Remove accelerator cable. Remove air
hose, air pipe and heat protectors. Disconnect clutch booster vacuum
hose. Remove air intake hoses and EGR pipe. Disconnect heated oxygen
sensor connectors.
2) Remove oil pipe and EGR valve. Disconnect exhaust fitting,
and remove rear heat protector. Remove oil return pipe. Remove
turbocharger assembly.
Inspection (All Models)
Check turbine and compressor wheels for cracking and other
damage. Ensure turbine and compressor wheels turn smoothly. Check for
oil leakage from turbocharger assembly. Check for proper wastegate
valve operation. See I - SYSTEM/COMPONENT TESTS article.
CAUTION: Apply light coat of oil to inner surface of flared area on
water pipe (flare nut fitting) before connecting to engine.
Installation (All Models)
1) To install, reverse removal procedure. Before oil pipe
flare nut (above turbocharger) is installed, pour clean engine oil
into turbocharger oil pipe installation hole. Ensure oil and air hoses
are properly installed and securely clamped.
2) Use NEW gaskets. Adjust accelerator cable (if necessary).\
Refill engine oil and coolant. Check for oil and coolant leaks.
Tighten all bolts to specification. See TORQUE SPECIFICATIONS.
