1986–1989 Acura Integra Service & Repair Manual (P/N 07PAX-A01-XXXXX)

• 2,006-page PDF set — 698-page 1986 Integra factory service manual; 792-page 1989 factory service manual; 245-page 1989 Electrical Troubleshooting Manual; 16-page collision-estimating/body-repair excerpt; and a 255-page illustrated parts-reference PDF for the 1989 Integra 3-door LS.
• Covers the DA1 5-door and DA3 3-door chassis, D16A1 DOHC engine, RS and LS grades, and manual or automatic transaxles in the documented 1986 and 1989 model editions.
• Engine chapters address removal and installation, cylinder-head and valve-train disassembly, timing-belt work, valve/seat/guide inspection, crankshaft and bearing service, pistons and connecting rods, oil-pump repair, cooling-system testing, and intake/exhaust service.
• Drivetrain material takes the clutch and manual transaxle through removal, internal inspection, synchronizer and differential repair, and reassembly. Automatic-transaxle coverage adds road and stall testing, hydraulic pressure diagnosis, valve-body and clutch service, torque-converter checks, differential work, and final adjustment.
• Chassis and body sections document power-steering pump and gearbox diagnosis, suspension alignment and hub/bearing service, front and rear brake repair, HVAC and air-conditioning testing, glass and sunroof work, body-panel service, and frame-reference information.
• Electrical support includes harness routing, fuse information, connector and component-location views, system schematics, and fault tracing for EFI, starting and charging, lighting and headlight retractors, gauges, power windows and locks, cruise control, rear defogger, wipers, and related control units. The parts-reference file adds 147 illustrated component groups from across the vehicle.

Technical Content Overview

Most mechanical repair information comes from the two Honda factory manuals. The earlier book is identified as the 1986 Integra Service Manual, First Edition 2/86. The later manual is the 1989 edition, issued as First Edition 9/88 with a second printing dated 9/89; its front matter states that the specifications apply to U.S. models. Both organize procedures by system and support them with component-specific torque tables, fluid-capacity data, service limits, valve-clearance and alignment specifications, pressure-test data, and electrical test values.

The D16A1 chapters cover the cylinder head, camshafts, valves and guides, timing drive, block, crankshaft, bearings, pistons, lubrication circuit, cooling system, fuel delivery, and intake and exhaust assemblies. PGM-FI and emissions material provides self-diagnostic information, symptom-to-system charts, sensor and signal checks, fuel-pressure and injector testing, ECU-related troubleshooting, and inspection coverage for the catalytic converter, PCV system, and evaporative controls.

Manual-transaxle sections cover the clutch release system, pressure plate, disc, flywheel, shafts, gears, synchronizers, shift mechanism, bearings, and differential. The automatic chapters combine operational diagnosis with internal repair of the shafts, clutches, valve bodies, governor components, differential, bearings, torque converter, controls, and lock-up system. Driveshaft and CV-joint sections address removal, seal protection, inspection, and installation requirements.

Manufacturer tool lists identify dedicated service equipment by number, including the 07993-PD6000A system-checker harness, 07406-0040000 fuel-pressure gauge set, and 07406-0010101 power-steering pressure gauge set. These references help a shop determine whether the specified fixture or a suitable equivalent is needed before beginning a repair.

Diagrams, Diagnostics, and Parts Identification

Representative visual references include the cylinder-head/valve-train illustrated index, PGM-FI troubleshooting flowcharts, automatic-transaxle pressure-test charts, power-steering gearbox section views, the body frame-repair chart, and 1989 power/ground-distribution and headlight-retractor schematics. The Electrical Troubleshooting Manual pairs many circuits with harness routes, connector IDs, splice and ground locations, and component-location photographs instead of providing schematic pages alone.

The 255-page parts-reference file is limited to the 1989 Integra 3-door LS. Its illustrated groups cover engine internals, fuel and exhaust parts, manual and automatic transaxle assemblies, steering, brakes, suspension, body panels, air conditioning, interior hardware, and wire harnesses. It is a web-captured dealer parts reference, not another factory service-manual volume.

The factory procedures also flag repair mistakes that can damage parts. The driveshaft sections warn that pulling on an inboard CV joint can separate it and that careless removal can damage the differential oil seal. Engine-installation notes explain that an incorrect mount-bolt tightening sequence or twisted mount bushings can cause vibration and shorten bushing life.

Coverage Boundaries

The factory repair manuals in this set are the 1986 and 1989 editions; the set does not include separate 1987 or 1988 factory service manuals. The Electrical Troubleshooting Manual is specifically marked for the 1989 Integra, First Edition 11/88. The 16-page collision file is a third-party estimating-guide excerpt with 1986–1989 Integra body, lamp, cooling, suspension, brake, panel, and structural labor groups, OEM part-number references, and underhood dimension information. It is not a Honda factory collision manual.

Because the set covers pressurized fuel and steering systems, refrigerant service, brakes, rotating assemblies, and electrical diagnosis, these procedures are intended for technicians or experienced owners using proper support equipment, service tools, and system-specific safety practices.
