The Mazda 6, produced from 2002 to 2008, represents a significant entry in the mid-size sedan and wagon market, embodying Mazda's 'Zoom-Zoom' philosophy with a focus on driving dynamics and engaging performance. Available in sedan (GG chassis code) and wagon (GY chassis code) body styles, this generation offered a choice between efficient 2.0L (LF-DE) and more powerful 2.3L (L3-VE) MZR engines, paired with either a 5-speed manual or a 4-speed automatic transmission. Known for its sharp handling and a comfortable ride, the Mazda 6 competed with established players like the Toyota Camry and Honda Accord, often praised for its more sporting character and practical wagon variant. Safety was a key consideration, with models earning high ratings in crash tests, especially when equipped with optional side and curtain airbags, and featuring standard Anti-lock Braking System (ABS) and Electronic Brake-force Distribution (EBD). This comprehensive service manual provides in-depth technical information for the Mazda 6, covering all major systems including the powertrain, chassis, and electrical components. It details essential maintenance procedures, from routine oil changes and filter replacements to more involved tasks like coolant flushes and spark plug services, along with recommended intervals. The manual also serves as a critical resource for diagnosing and repairing issues, offering troubleshooting guides, diagnostic trouble codes (DTCs), and detailed repair procedures for engine, transmission, suspension, braking, and electrical systems. With clear diagrams, specifications, and explanations of component testing and installation, this manual is an indispensable tool for owners, DIY enthusiasts, and professional technicians seeking to maintain, repair, and optimize their Mazda 6. 🏷️ Basic Information Identification Make: Mazda Model: Mazda 6 Model Code: GG/GY (First Generation), GH (Second Generation) Production Years Covered: 2002, 2003, 2004, 2005, 2006, 2007, 2008 Codes Chassis Codes: GG (Sedan/Hatchback), GY (Wagon) Engine Codes Common: LF-DE (2.0L), L3-VE (2.3L), Y6 (Diesel - less common in North America) 👋 Introduction Market Position Segment: Mid-size sedan/wagon.
