This manual covers the L-Series, including DL, GL, GL-10, RX, and Loyale variants, produced from 1984 through 1994. These vehicles are recognized for their horizontally-opposed boxer engines, durable construction, and the significant advantage of Symmetrical All-Wheel Drive, which was often standard or optional, enhancing their reliability and capability, particularly in challenging weather and light off-road conditions. The L-Series established Subaru's reputation in the compact and subcompact economy car and station wagon market, offering a blend of practicality and robust engineering that appealed to a wide range of drivers. This comprehensive factory service manual provides detailed information essential for the maintenance, repair, and troubleshooting of your L-Series vehicle. It covers all major systems, including engine mechanicals and management, transmissions (manual and automatic), drivetrain, brakes, suspension, steering, and the electrical system. Within its extensive pages, you will find step-by-step procedures for component overhauls, scheduled maintenance, diagnostic routines, and technical specifications, equipping owners, mechanics, and technicians with the knowledge needed to keep these vehicles in optimal working order. 🏷️ Basic Information Identification Make: Subaru Model: L-Series Model Variant: DL, GL, GL-10, RX, Loyale (some
