PDF Search, Diagram Detail and Page Count

Search and navigation: Text search is available through much of the workshop material, but the introduction, index, much of the HVAC chapter, and several other pages are not searchable. There are no embedded PDF bookmarks. Small labels in dense wiring diagrams require zooming.

One printable English PDF with 1,087 pages, including nine front-matter pages: the cover, introduction, and seven-page service index.

Engine Overhaul, Drivetrain Repair and System Diagnostics

These selected repair topics introduce the manual’s coverage; further subjects include adhesive wheel-balance weights and frame repair charts.

• Engine repair: Engine removal and installation, cylinder-head service, VTEC testing, valve adjustment, cam-chain timing, crankshaft and piston work, and oil-pump overhaul.

• Cooling system: Pressure tests, thermostat and fan diagnosis, water-pump replacement, radiator service, coolant replacement, and air bleeding.

• Clutch and transmission: Hydraulic clutch service, clutch and flywheel replacement, transmission teardown, shaft and synchro inspection, preload adjustment, and reassembly.

• Rear differential and driveline: Torsen LSD checks, differential removal and reassembly, bearing and backlash adjustments, driveshaft service, and propeller-shaft inspection.

• Steering and suspension: EPS fault tracing, torque-sensor neutral-position memorization, steering rack and column service, wheel alignment, and suspension repairs.

• Brakes and ABS: Hydraulic bleeding, caliper overhaul, brake-booster checks, parking-brake adjustment, and four-channel ABS troubleshooting.

• Electrical and cabin systems: PGM-FI/OBD-II diagnosis, starting and charging tests, HVAC troubleshooting, convertible-top controls, body electrical circuits, and SRS service.

Suited to mechanics and experienced owners comfortable with internal engine measurements and electrical fault tracing; several procedures require Honda diagnostic equipment and special tools.

Model-Year Differences and Engine Repair

Identification and maintenance: Year-specific identification pages distinguish VIN, engine-number, transmission-number, and paint-code information. Normal- and severe-condition maintenance schedules are separated for the 2000 model and the 2001–2003 models.

Cylinder head and block: Step-by-step procedures cover cam-chain installation, cylinder-head removal and warpage inspection, rocker-arm and shaft disassembly, camshaft inspection, valve-guide replacement, and valve-seat reconditioning. Crankshaft-pulley service and final cylinder-head installation are also documented.

Internal engine work includes main- and connecting-rod bearing selection and replacement, crankshaft and piston inspection, FRM cylinder-liner honing requirements, piston-ring service, and in-car crankshaft-seal replacement. Intake-manifold and exhaust-system removal procedures accompany lubrication and cooling-system repair information.

The cam-chain cautions explain how magnetization can cause misfires or false diagnostic codes. Engine-installation notes identify how an incorrect mount-fastening sequence can cause noise, vibration, and shortened bushing life.

Clutch, Transmission and Torsen Service Limits

Clutch controls: Pedal and switch adjustment, master- and slave-cylinder replacement, hydraulic bleeding, release-bearing inspection, and pressure-plate and flywheel checks support clutch diagnosis and replacement.

Transmission internals: Mainshaft, countershaft, and secondary-shaft procedures include shift-arm and fork service, synchro-ring and gear inspection, sleeve and hub checks, oil-pump clearance, secondary-shaft preload, and mainshaft thrust-clearance adjustment.

Differential scope: Case assembly work includes oil-seal replacement, backlash inspection, bearing preload, gear-tooth contact checks, and mount replacement. The Torsen LSD unit itself is non-serviceable except for its tapered roller bearings; a faulty unit is replaced as an assembly. Driveshaft and propeller-shaft sections address the surrounding driveline.

Fault Tracing, Steering and Brake Checks

PGM-FI diagnosis: DTC indexes, symptom charts, freeze-frame data, and MIL/DLC circuit checks connect a reported fault with the relevant tests. ECM reset and idle-learn procedures accompany fuel-pressure testing, injector and sensor service, EVAP diagnosis, and pulsed secondary-air injection troubleshooting.

The DLC location differs between 2000–2001 and 2002–2003 cars. These year-specific details help identify the correct diagnostic connection before testing.

EPS and ABS: Control-unit input/output tables, indicator-circuit diagnosis, wheel-sensor checks, and DTC flowcharts support electrical fault isolation. The EPS section specifies neutral-position memorization after gearbox removal or installation, or torque-sensor or control-unit replacement.

Steering-joint installation specifications change at documented VIN breaks. Steering repair also addresses cable-reel centering to prevent open wiring that can disable the SRS and horn.

Body, HVAC and Electrical Reference Material

Body procedures cover doors and glass, interior trim, bumpers, subframes, convertible-top mechanisms and motors, and removable-hardtop provisions. Electrical coverage extends to cruise control, keyless entry, power locks and windows, lighting, gauges, the immobilizer, and SRS components.

HVAC diagnosis and service: Heater-control self-diagnosis, control-motor tests, compressor-clutch troubleshooting, evaporator and heater-core replacement, refrigerant recovery, evacuation, charging, and leak testing are included.

Illustrated references include the Starting System, EPS, ABS Components, and Convertible Top circuit diagrams, plus transmission-housing and rear-differential exploded views. Connector views and troubleshooting charts accompany the relevant system tests.

Tools and specifications: Procedure-specific references include holder handle 07JAB-001020A, 50 mm holder attachment 07JAB-001040A, and clutch alignment shaft 07LAF-PT00110. Other examples are differential oil-seal driver 07JAD-P190100, brake pushrod adjustment gauge 07JAG-SD40100, and SRS inflator simulator 07SAZ-TB4011A.

Torque tables, fluid and refrigerant data, electrical test values, wear limits, clearances, and alignment specifications accompany the repair procedures. Fuel pressure, refrigerant handling, brake hydraulics, rotating engine parts, and pyrotechnic SRS components require the manual’s specified precautions and suitable shop equipment.

A Preview of Oil-Pressure and Differential Checks

For the F20C1 oil-pressure test at an oil temperature of 176°F (80°C), the manual specifies minimum pressure of 250 kPa (36 psi) at idle and 590 kPa (85 psi) at 3,000 rpm.

Rear-differential inspection specifies ring-gear backlash to the drive pinion of 0.09–0.11 mm (0.0035–0.0043 in.), alongside the bearing-preload and gear-contact checks.
