2002–2006 Acura RSX and RSX Type-S OEM Service Manual

• 1,104-page OEM service publication covering the 2002–2006 Acura RSX and RSX Type-S.
• Full technical specifications for the K20A2 and K20A3 DOHC VTEC engines.
• Contains 100+ exploded-view diagrams, 15+ electrical schematics, and critical torque specs.

Document Scope and Workshop Value

This factory-authorized publication is the primary technical resource for the DC5 platform. Whether you are dealing with routine suspension geometry alignments or troubleshooting complex ABS faults, having the correct factory data eliminates costly guesswork. The manual breaks down the vehicle into 23 specialized sections, covering everything from complete engine mechanical data to differential servicing and wiring schematics. Because this manual is provided as an instant download, you can immediately access the detailed exploded-view indices on your laptop or tablet. This allows you to visually confirm disassembly sequences and critical thread sizes while standing right next to the car.

Specification and Data Highlights

Precision is everything when rebuilding a K-series motor. This documentation provides the exact factory reference values needed for engine assembly and tuning. For example, cylinder head specifications clearly document valve clearance tolerances at 0.21–0.25 mm for the intake and 0.25–0.32 mm for the exhaust. The block data tables specify piston-to-cylinder clearances down to a tight 0.020–0.040 mm, alongside the crankshaft main journal diameter (54.984–55.008 mm for the K20A3). You will also find exact fluid capacities, such as the 1.7-liter requirement for a transmission overhaul using Honda MTF, and electrical reference values for the 12V alternator (90A/95A output).

Working on engine internals and heavy drivetrain components involves significant physical hazards and requires strict attention to detail. Always ensure the vehicle is properly secured on stands or a lift, and cross-reference these baseline figures with the complete, step-by-step procedures inside the manual before executing any heavy mechanical work.
