1990–1999 Mitsubishi Eclipse Spyder Service Manual (P/N 00109000171)

• Details the 1990–1999 Mitsubishi Eclipse Spyder and related FWD/AWD variants equipped with 2.0L and 2.4L engines.
• Official Mitsubishi Motors Corporation publication (P/N 00109000171) providing factory maintenance and diagnostic specifications for the 4G6 and 420A engine platforms.
• Includes 83 exploded-view diagrams, 14 wiring schematics, diagnostic troubleshooting flow charts, vacuum circuit diagrams, shift pattern charts, and standard tooth contact pattern drawings.
• Serves as the primary reference for chassis and engine rebuilds, noting specific variations for federal and California emissions compliance (1996 edition).
• Explores front and rear suspension, propeller shafts, clutches, and power plant mounts.
• Outlines parking brakes, interior components, exterior body panels, heaters, and air conditioning.

Engine and Chassis Overview

This manual breaks down the 4G6 and 420A engine platforms, outlining technical data for cooling, intake, exhaust, fuel systems, and both manual and automatic transaxles. It highlights factory-recommended inspection points for the Supplemental Restraint System (SRS), steering, and braking systems, alongside clear schedules for body exterior maintenance. Detailed step-by-step instructions for tasks that typically demand an expensive trip to the dealership, such as complete timing belt replacements, hydraulic lash adjuster leak-down tests, and internal transaxle overhauls, allow users to bypass dealership labor rates. Because automotive repair carries inherent physical risks and requires proper tooling, always review the included safety precautions and handling procedures before starting any diagnostic work or teardown.

Torque, Fluid & Electrical Specifications

Quick-reference tables list essential maintenance data, including fluid capacities and tightening torques for all major assemblies. The manual documents critical wear limits, such as the 99.4 mm (3.91 in.) maximum cylinder head bolt length. Intake manifold vacuum is specified at a 60 kPa (18 in.Hg) minimum, and compression pressure for the 4G6 engine is listed at a 1250 kPa (178 psi) standard. Timing belt installation and auto-tensioner adjustments are clearly mapped out to verify accurate component positioning. Reviewing structured factory workshop documentation directly on a shop laptop accelerates the repair process by providing exact OEM pinout testing values and component clearances, drastically reducing diagnostic time for complex drivability issues.

When executing a major engine rebuild, special attention is required for the 4G63 crankshaft end play; strictly adhering to the 0.05-0.18 mm tolerance during main bearing installation is critical to prevent severe thrust bearing failure, commonly known as crankwalk. Additionally, compressing the timing belt auto-tensioner rod too rapidly will permanently damage the cylinder, mandating a slow, vise-controlled compression.

At 2,103 pages, this complete OEM service manual PDF delivers the exact engine, chassis, electrical, and fuel-injection data needed to properly service the Eclipse Spyder.
