Acura Integra 1986–1989 Service Manual Set (P/N 61SD203)

Use the service manuals for mechanical testing and repair, the electrical manual to trace a circuit from the schematic to the vehicle, and the illustrated parts reference to identify components before ordering. The collision excerpt adds labor entries, part-number references, and underhood dimensions for estimating body work.

The set has separate factory service manuals for 1986 and 1989. The collision excerpt and 1989 electrical manual have their own model-year coverage. The collision file is a third-party estimating reference.

PDF Search, Bookmarks, and Wiring Detail

The parts reference has searchable text for part numbers and descriptions. The two service manuals, electrical manual, and collision excerpt have no searchable page text. Both service manuals and the electrical manual have bookmarks, and the parts reference has bookmarks for its illustrated groups. The collision excerpt has no bookmarks. Small wire-color codes and connector labels are easier to read with zoom, especially in the foldout wiring diagrams and densely shaded circuit schematics.

The ZIP contains five printable English-language PDFs totaling 2,006 pages. That count includes the cover and front matter where present, the wiring sheets in the 1989 service PDF, and all 16 pages of the estimating excerpt, including its guide material and pages with Acura Legend entries.

Engine Repair, Transaxle Testing, and Wiring Diagnosis

This selected overview highlights the main repair and diagnostic references. The service manuals also include lift and support points and towing information.

• Engine and cooling: Engine removal and installation, timing-belt service, cylinder-head and valve-train inspection, crankshaft and bearing work, piston and connecting-rod service, oil-pump repair, and cooling-system tests.
• PGM-FI and emissions: Self-diagnostic checks, symptom charts, sensor and ECU signal tests, fuel-pressure and injector testing, and checks for the catalytic converter, PCV system, and evaporative controls.
• Clutch and transaxles: Clutch and flywheel inspection, manual gear and synchronizer service, automatic road and stall tests, hydraulic pressure diagnosis, and valve-body, clutch, differential, and torque-converter coverage.
• Steering, suspension, and brakes: Power-steering pump and gearbox checks, wheel alignment, hub and bearing service, and front and rear brake repair.
• Body and climate control: Frame-reference dimensions, body-panel and glass service, sunroof work, and heater and air-conditioning tests.
• Electrical fault tracing: Power and ground distribution, fuse information, harness routes, and circuit coverage for starting and charging, headlight retractors, gauges, windows, locks, cruise control, wipers, and the rear defogger.

Service Limits and Shop Preparation

The cylinder-head specifications list a warpage service limit of 0.05 mm (0.002 in.). For compression testing at wide-open throttle, the 1986 manual lists a minimum of 1,127 kPa (164 psi) at 300 rpm, while the 1989 manual lists 932 kPa (135 psi) at 250 rpm.

The 1986 special-tool lists identify the system-checker harness (07993-PD6000A), fuel-pressure gauge set (07406-0040000), and power-steering pressure gauge set (07406-0010101). These references help a shop check which equipment it needs before starting diagnosis. The driveshaft and engine-installation sections also flag the risk of separating an inboard CV joint, damaging a differential oil seal, or introducing vibration by leaving the engine-mount bushings twisted.

Connector Locations, Parts, and Labor References

The electrical manual pairs circuit diagrams with splice and ground IDs, connector views, and location photos. For a headlight retractor fault, the schematic identifies the circuit connections and the photos show where to find the relay and connectors on the car.

The illustrated parts reference groups components by assembly, including engine internals, manual and automatic transaxles, steering, brakes, suspension, HVAC, trim, body panels, and wire harnesses. The collision excerpt adds estimating entries for lamps, cooling components, suspension, brakes, panels, and structural work.
