Document Content Overview

The 1991 Mitsubishi 3000GT service manual provides a structured repository for mechanical service data across the vehicle's primary systems. The content begins with a comprehensive General section detailing vehicle identification codes, safety certification labels, and specific lifting/towing procedures for both FWD and AWD drivetrain configurations. The manual then transitions into detailed engine group documentation, which encompasses the V6 DOHC engine construction, internal lubrication circuits, and maintenance schedules for components like the timing belt, oil filter, and cooling system.

Subsequent chapters categorize technical data for fuel supply, exhaust systems, and emissions control. Detailed reference materials cover the cooling system's freezing-point-to-specific-gravity charts, along with specialized technical depth for the manual and automatic transaxles. The documentation provides clear service procedures for steering, suspension, braking, and interior components including the Supplemental Restraint System (SRS). Each chapter includes exploded-view diagrams that correlate with tightening-torque specifications, identifying specific bolt and nut values in Nm and ft-lbs.
