Mitsubishi 3000GT 1992–1996 Service Manual, Vol. 1 (P/N MSSP-001B-96)

Mitsubishi’s 1992–1996 3000GT Backup Service Manual, Volume 1 (P/N MSSP-001B-96), covers the 3000GT, 3000GT SL, and 3000GT VR-4 with the 6G72 DOHC engine. It includes non-turbo FWD and turbo AWD configurations, hatchbacks, and 1995–1996 two-door convertibles.

PDF Search, Bookmarks, and Diagram Detail

Search and diagram limitations: Text search works across the main chapters, but some tables and cover data are not searchable. Chapter bookmarks are included; “Back to Navigator” points to a separate file. Small schematic labels require zooming, and some overprinted ECM connector numbers remain difficult to read. Two transaxle reference pages are out of sequence.

One printable English PDF contains 1,308 pages, including two cover pages, 15 notes pages, and 14 blank pages.

Engine, Driveline, and Chassis Service

The following selected topics outline the repair and diagnostic coverage. Other included subjects include power-seat motor checks and windshield-wiper service.

• Engine service: Step-by-step procedures for engine removal and installation, timing-belt service, cylinder-head gasket replacement, and camshaft and crankshaft oil-seal replacement.

• Fuel and emissions: Sensor and injector checks, fuel-pressure testing, ignition diagnosis, turbocharger wastegate checks, variable induction, EGR, and EVAP troubleshooting.

• Transaxles and driveline: Clutch adjustment and bleeding, transaxle removal, automatic-transaxle pressure and stall tests, transfer-case service, and propeller-shaft and drive-shaft repair.

• Brakes, suspension, and steering: ABS fault isolation and actuator checks, brake bleeding, hydraulic-unit testing, wheel alignment, hub and bearing inspection, and power-steering pressure testing and bleeding.

• Body and exterior: Active aero diagnosis, door and window adjustment, removable and power sunroof service, central locking, and keyless-entry code registration.

• Supplemental restraints: SRS diagnosis, post-collision inspection, component replacement information, and construction, configuration, and circuit diagrams.

• Heating and air conditioning: Manual and full-auto A/C diagnosis, R-12 and R-134a service information, compressor checks, refrigerant-leak repair, and control-unit circuit testing.

Its scan-tool diagnostics, factory special-tool references, and system-level repair procedures make it best suited to experienced technicians and well-equipped repair shops.

Engine Repair and Emissions Diagnosis

The engine chapter also covers lash-adjuster inspection and replacement, compression and manifold-vacuum testing, oil-pan service, and the engine oil cooler. Cooling-system procedures address radiator removal, cap and leak testing, thermostat inspection, and water-pump replacement.

Front and rear turbocharger removal and inspection are treated separately. Variable-induction and active-exhaust diagnosis distinguish these systems from the turbocharger wastegate controls.

MFI troubleshooting: Symptom and DTC charts, ECM terminal checks, sensor waveform tests, and MFI system diagrams distinguish turbo, non-turbo, Federal, and California applications. Year- and emissions-specific vacuum circuit diagrams support hose and control-system diagnosis.

Dedicated 1996 sections cover OBD-II trouble codes, freeze-frame data, and drive-cycle checks. These records support investigation of intermittent faults by showing the operating conditions present when a malfunction was detected.

Tooling: Factory tables identify the MB991341 MUT, MB991502 MUT-II, MD998051 cylinder-head bolt wrench, and MD998767 tensioner pulley socket wrench. These references help establish the equipment needed before starting a repair. MUT-II adapter guidance is included for earlier vehicles.

Transaxle Variants and Differential Repair

The manual distinguishes the F5M33 FWD manual and F4A33 automatic from the AWD W5MG1 used through 1993 and W6MG1 used from 1994. Automatic-transaxle test charts connect hydraulic-pressure findings with possible faults and corrective work.

Rear-differential coverage extends to carrier disassembly and reassembly, pinion and bearing adjustment, tooth-contact inspection, and limited-slip differential case service.

The automatic-transaxle installation notes warn that mounting the torque converter on the engine first can damage the transaxle oil seal.

Overhaul limits: Internal engine overhaul and internal manual/automatic transmission overhaul require the separately issued factory manuals. This volume provides on-vehicle diagnosis, removal and installation, adjustment, and the component repair procedures included in its chapters.

ECS, Four-Wheel Steering, and ABS Differences

Electronic Control Suspension coverage includes service data, diagnostic codes, actuator checks, and forced-drive testing through 1995. Conventional 4-wheel steering coverage includes function checks and rear hydraulic-system service.

Active Preview ECS and Active 4WS are not included. ABS troubleshooting separates FWD and AWD systems and identifies circuit changes around the October/November 1994 production transition.

Body Equipment and Climate Controls

Convertible identification and chassis/brake information are included, but this is not a convertible-roof mechanism repair manual.

Cruise-control diagnosis includes input checks, component layouts, and control-unit testing. Full-auto A/C coverage adds control-unit terminal checks and circuit diagrams for sensors, damper motors, and blower controls.

Component-specific torque tables, fluid capacities, pressure-test data, wear limits, clearances, and electrical test values accompany the relevant service sections.

SRS Precautions and Electrical Scope

SRS coverage distinguishes driver-side systems through 1993 from driver and passenger systems from 1994. The clock-spring installation cautions explain how incorrect alignment can sever the internal flat cable and disable the restraint system.

Mitsubishi restricts SRS work to authorized dealer personnel because improper service can deploy an air bag or leave the restraint system inoperative.

Volume 1 only: The separate Volume 2 “Electrical” manual is not included. This file contains system-specific diagnostic circuits, but it does not replace the complete vehicle wiring and electrical volume.

Examples of Timing-Belt and Cooling Inspection Data

The 6G72 timing-belt inspection specifies an auto-tensioner rod projection of 3.8–4.5 mm, shown with the tensioner illustration and post-adjustment check.

Cooling-system data distinguish the cap’s standard high-pressure-valve opening range of 75–105 kPa from its 65 kPa service limit. Thermostat inspection specifies opening at 76.5°C and full opening at 90°C.
