thoroughly with soap and water.
CAUTION: Never use non-detergent or straight mineral oil.
FUEL SYSTEM SERVICE
WARNING: Relieve fuel system pressure prior to servicing any fuel
system component (fuel injection models).
HALOGEN BULBS
Halogen bulbs contain pressurized gas which may explode if
overheated. DO NOT touch glass portion of bulb with bare hands. Eye
protection should be worn when handling or working around halogen
bulbs.
RADIATOR CAP
CAUTION: Always disconnect the fan motor when working near the
radiator fan. The fan is temperature controlled and could
start at any time even when the ignition key is in the OFF
position. DO NOT loosen or remove radiator cap when cooling
system is hot.
RADIATOR FAN
WARNING: Keep hands away from radiator fan. Fan is controlled by a
thermostatic switch which may come on or run for up to 15 minutes even
after engine is turned off.
WARRANTY INFORMATION
CAUTION: Due to the different warranties offered in various regions
and the variety of after-market extended warranties
available, please refer to the warranty package that came
with the vehicle to verify all warranty options.
FUSES & CIRCUIT BREAKERS
FUSE PANEL LOCATION
The electrical system is protected against shorts by fuses
that are designed to fail, to prevent damage to the wire harness. The
fuse block is located under the instrument panel on the driver's side.
If a fuse is blown, locate the cause before replacing the fuse. Spare
fuses are contained in the fuse block.

PASSENGER COMPARTMENT

1) Relieve fuel pressure. See FUEL SYSTEM PRESSURE RELEASE.
Disconnect negative battery cable. Drain coolant. Remove air intake
hose. Remove throttle body and gasket with control cables and vacuum
hoses attached.
2) Remove EGR pipe (if equipped). Disconnect power brake
hose. Label and disconnect vacuum hoses and wiring harness connectors
as necessary. Remove intake plenum brackets and mounting bolts. Remove
intake plenum and gasket.
3) Disconnect high pressure fuel hose at fuel rail.
Disconnect fuel return hose. Disconnect vacuum hoses. Disconnect
injector electrical connectors. Remove fuel rail bolts, and lift fuel
rail and injectors from engine. Injectors may be removed after fuel
rail is removed from intake manifold.
Installation
To install, reverse removal procedure. Use NEW insulators and
"O" rings when installing injectors. Install injectors into fuel rail
with a twisting motion. Ensure injectors rotate smoothly when
installing. Refill cooling system.
Removal (Eclipse, Galant, Mirage & Montero Sport 3.0L)
1) Relieve fuel pressure. See FUEL SYSTEM PRESSURE RELEASE.
Disconnect negative battery cable. Disconnect PCV hose and breather
hoses. Disconnect high pressure fuel hose at fuel rail. Disconnect
fuel return hose and vacuum hoses.
2) Disconnect injector electrical connectors. Remove fuel
rail bolts, and lift fuel rail and injectors from engine. Injectors
may be removed after fuel rail is removed from intake manifold.
Installation
To install, reverse removal procedure. Use NEW insulators and
"O" rings when installing injectors. Use lubricant on "O" rings.
Install injectors into fuel rail with a twisting motion. Ensure
injectors rotate smoothly when installing.
Removal (Montero)
1) Relieve fuel pressure. See FUEL SYSTEM PRESSURE RELEASE.
Disconnect negative battery cable. Remove air intake hose. Remove
accelerator cable adjusting bolts. On A/T models, remove throttle
control cable. On all models, remove accelerator cable. Label and
disconnect all vacuum hoses from throttle body and upper intake
manifold (air intake plenum).
2) Remove EGR pipe and gasket. Remove ignition coil (if
necessary). Remove engine oil filler neck bracket. Disconnect PCV
hose. Remove throttle body, leaving coolant hoses connected. Remove
throttle body gasket. Remove front and rear intake plenum brackets.
Remove intake plenum mounting bolts. Remove intake plenum and gasket.
3) Disconnect high pressure fuel hose at fuel rail.
Disconnect fuel return hose. Disconnect vacuum hoses. Disconnect
injector electrical connectors. Remove fuel rail bolts, and lift fuel
rail and injectors from engine. Injectors may be removed after fuel
rail is removed from intake manifold.
Installation
To install, reverse removal procedure. Use NEW insulators and
"O" rings when installing injectors. Use lubricant on "O" rings.
Install injectors into fuel rail using a twisting motion. Ensure
injectors rotate smoothly when installing. Adjust throttle control and
accelerator cables (if necessary). Refill cooling system.
HEATED OXYGEN SENSOR (HO2S)
Removal & Installation

2) Disconnect air intake hose and vacuum hoses. Remove air
hose and air outlet housing. Remove heat protectors. Disconnect

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.
