2) Disconnect pressure hose from oil pump. See Fig. 45.
Install Adapter (MB990993) on oil pump. Install Adapter (MB990994) o\
n
disconnected hose. Connect Pressure Gauge (MB990662) and shutoff valve\
between adapters. Open shutoff valve. Bleed steering hydraulic system.

3) Install a thermometer in fluid reservoir. Start engine and
allow it to idle. Turn steering wheel several times until fluid
temperature reaches 122-140
F (50-60C). Disconnect PSP switch
connector. Install a DVOM between ground and PSP switch terminal. See
Fig. 45 . Note continuity reading on DVOM. Go to next step.
4) With engine idling, gradually close shutoff valve to
increase power steering system pressure. Check pressure when PSP
switch is actuated by watching for a change in continuity. PSP switch

3000GT
DESCRIPTION & OPERATION
NOTE: The terms generator and alternator are interchangeable.
Mitsubishi generators are conventional 3-phase, self-
rectifying type units containing 6 diodes (3 positive and 3 negative)
which are used to rectify current. All models use a case-mounted
Integrated Circuit (IC) voltage regulator.
Generator relay or resistor with diode is used to ensure
charging of battery even if charging indicator light is defective.

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.
