Mitsubishi Eclipse / Eclipse Spyder 1995–1999 Service Manual Set

The paired service volumes combine mechanical repair procedures with electrical diagnosis and wiring references. The Technical Information Manual explains system construction and operation; its foreword calls for use alongside the service manuals.

Coverage varies by publication. The 4G6 booklet provides engine-family procedures, including chapters labeled for Galant and Space Wagon, rather than complete vehicle service coverage for those models. Its GDI material is separate from the Eclipse MFI applications. The 1999 file is a transmission-control diagram reference, not an OEM service manual.

PDF Search, Navigation and File Contents

Search and diagram detail: The service volumes and Technical Information Manual have OCR text, but recognition is imperfect and some content is not searchable. The 4G6 booklet supports text search. In the 1999 diagram file, surrounding text is searchable but the diagram images are not. Chapter bookmarks are available in both service volumes and the engine booklet; the other two PDFs have none. Small wiring labels require zooming, and some dense pin numbers remain difficult to distinguish in the Electrical volume and the 1999 diagrams.

The ZIP contains five printable PDFs totaling 3,139 pages, including covers, notes pages and the engine booklet’s revised and added pages. The separately listed seven-page diagram reference is included in that total.

Engine Overhaul, Driveline Repair and Circuit Diagnosis

These selected content highlights summarize the main workshop areas rather than reproduce the full contents. Further topics include auto-cruise control testing and sunroof service.

• Engine repair: Step-by-step removal, installation and overhaul procedures for the 420A, turbocharged 4G63 and SOHC 4G64, including timing belts, cylinder heads and internal components.

• Transaxles and AWD driveline: Clutch repair, unit removal, internal overhaul, hydraulic pressure and stall tests, preload and backlash adjustment, transfer-case service and propeller-shaft work.

• Brakes and steering: Separate FWD/AWD ABS diagnosis, brake overhaul, power-steering bleeding, and steering pump and gear service.

• Suspension and body: Wheel alignment, suspension component replacement, and Eclipse Spyder convertible-top troubleshooting, fit adjustment and drive-component service.

• HVAC and SRS: Refrigerant charging, leak diagnosis, performance testing, compressor service, SRS troubleshooting, post-collision diagnosis and airbag-module disposal information.

• Electrical testing: Component and connector locations, harness configuration drawings, wiring diagrams, charging and ignition tests, and MUT-II trouble-code, data-list and actuator checks.

This material is suited to professional technicians and experienced repairers with scan-tool access, pullers, press equipment, and the measuring tools required for internal engine and transaxle work.

Engine and Powertrain Detail

Engine components: The overhaul sections address rocker arms and camshafts, valve guides and stem seals, counterbalance shafts, the front case and oil pan, pistons and connecting rods, crankshaft, flywheel and drive plate. Related tables supply torque sequences, wear limits, clearances, sealants and plastic-area bolt-tightening data.

Timing and valve-train tools: The 4G6 booklet identifies the MD998738 timing-belt set screw, MD998767 tensioner socket wrench, MD998440 lash-adjuster leak-down tester and MB991654 cylinder-head bolt wrench. Lash-adjuster cleaning and leak-down testing are described alongside component inspection.

Manual transaxles: F5MC1, F5M31, F5M33 and W5M33 sections provide sectional drawings and procedures for synchronizers, shafts, differentials and transfer assemblies. Adjustment information covers shims, spacers, snap rings, end play and preload. The F5MC1 output shaft is serviced as a unit; its internal disassembly is not permitted.

Automatic transaxles: F4AC1, F4A23, F4A33 and W4A33 material includes hydraulic circuits, clutch air-pressure checks and unit overhaul. The F4AC1 section also covers TCM resetting and pinion-factor writing after TCM replacement or a tire-size change.

Electrical Diagnosis and Body Systems

Representative drawings include engine-family MFI circuits, ELC four-speed automatic-transaxle control, FWD/AWD ABS, SRS, Spyder convertible-top control and engine/body harness configurations.

Connector-face views, grounding points, junction blocks and component-location pages support circuit tracing. Used with the symptom charts, diagnostic trouble codes, scan-tool data lists and actuator tests, these references let a technician follow a fault from the diagnostic chart to the relevant connector and circuit.

Spyder body diagnosis: Convertible-top and power-window symptom flowcharts distinguish switch, wiring, motor and control-module faults. Body procedures also cover top fit and drive-component service.

Component-specific cautions: The 4G6 booklet warns that disturbing the retained bolts in a flexible flywheel can upset its assembly balance and damage the flywheel. Forcing the lash-adjuster bleed wire can damage the weak internal check-ball spring and disable the adjuster.

The service manual restricts SRS work to an authorized Mitsubishi dealer. Air-conditioning, fuel-system, engine and driveline work require the specified isolation, lifting and shop-safety precautions.

Selected Lash-Adjuster and Crankshaft Inspection Data

The 4G6 booklet specifies a lash-adjuster leak-down time of 3–20 seconds per 1 mm with diesel fuel at 15–20°C, alongside the cleaning and testing procedures.

Its crankshaft inspection table gives standard end play of 0.05–0.25 mm and a service limit of 0.40 mm, distinguishing the normal range from the replacement threshold.
