1986–1989 Honda Accord STD, LX, GL, EX, EXi Factory Service Manual

• Model and configuration coverage: Identifies 1986–1989 Honda Accord CA4 1600 and CA5 2000 applications in the factory 3D and 4D groups, including the four-door sedan, three-door Glass-Back/hatchback, and Aerodeck where applicable. The identification tables list STD, GL, LX, EX, EXi, EXSi, EXR/LXC, EXC, EXCi, and EXSCi grades, depending on market and year.
• Engine repair and overhaul content: Documents engine removal and installation, cylinder-head and valve-train service, SOHC and DOHC timing-belt work, cylinder-block inspection, crankshaft/piston/bearing procedures, lubrication-system repair, and intake/exhaust service for the A16A1, A20A1, A20A2, A20A3, A20A4, B20A2, and B20A8 engines.
• Fuel, emissions, and diagnosis: Covers carburetor systems and PGM-FI, including vacuum/electrical interconnect diagrams, control-unit and sensor fault isolation, fuel-pressure testing, injector and idle-control checks, and emission-system troubleshooting.
• Transmission and driveline: Details clutch service, five-speed manual and four-speed automatic removal, internal disassembly and reassembly, road testing, hydraulic-pressure diagnosis, differential repair, and driveshaft/intermediate-shaft service.
• Chassis, brakes, HVAC, and electrical: Brings together manual and power-steering repair, wheel alignment and suspension work, conventional brakes plus 4W-ALB and later three-channel ALB diagnosis, heater/A/C testing, charging and starting-system repair, body-electrical tests, connector views, and wiring diagrams.
• Five-publication factory set: Totals 1,710 PDF pages — 1986 maintenance and repair manual: 835 pages; 1986 construction and function manual: 177 pages; 1987 supplement: 242 pages; 1988 supplement: 340 pages; 1989 supplement: 116 pages.

The five books do different jobs. The 1986 maintenance and repair manual carries the core workshop procedures, while the separate construction-and-function book explains how the major systems are laid out and operate. The 1987, 1988, and 1989 supplements cover model-year changes instead of reprinting unchanged chapters. That distinction matters: the 1988 supplement omits suspension and body sections, while the 1989 supplement omits cooling, steering, suspension, body, and heating/air-conditioning sections. Those jobs remain in the earlier publications.

The title pages identify the supplied revisions as follows: base manual, First Edition 10/85 and Third Print 11/89; construction-and-function manual, First Edition 10/85 and Second Print 3/89; 1987 supplement, First Edition 9/86 and Second Print 2/90; 1988 supplement, First Edition 1/88; and 1989 supplement, First Edition 9/88.

Engine coverage is not limited to the A16A1 and A20A4. The manuals separate carbureted and fuel-injected SOHC A-series applications, then add the B20A2 and B20A8 DOHC engines with their own cylinder-head, timing, block, lubrication, intake/exhaust, fuel-control, and ignition information. Factory reference material includes component-specific torque tables, bearing and piston clearances, valve-adjustment data, inspection and wear limits, lubrication specifications, and engine-specific service limits. Because the set spans several regional market codes, use the CA4/CA5 identification pages to match the engine, grade, body, and transmission before selecting repair data.

Transmission selection is just as configuration-sensitive. Early applications use A1M5, A2K5, and B2K5 manual transmissions; later supplements add E1M5, E2K5/E2L5/E2S5, and F2K5/F2X5 variants. Four-speed automatic coverage centers on the F4 and C9. Procedures include clutch adjustment and replacement, manual-transmission removal, shaft and gear inspection, automatic-transmission troubleshooting and road tests, hydraulic-pressure testing, torque-converter and valve-body repair, differential service, shift-control adjustment, and final operational checks.

The diagnostic depth is visible in the illustrations and test material. Representative examples include PGM-FI vacuum/electrical interconnect diagrams and troubleshooting flowcharts, automatic-transmission hydraulic schematics and pressure-test charts, ALB functional-test and fault-isolation charts, heater circuit and air-door-position diagrams, gauge-cluster connector/terminal layouts, and retractable-headlight wiring and troubleshooting pages. Honda tool references include the 07406-0040000 fuel-pressure gauge set, 07999-PD6000A PGM-FI system-checker harness, 07GAC-PF40100 transmission-housing puller, 07406-0010200 power-steering pressure gauge assembly, and 07GAZ-SE00100 ALB hand-pump assembly.

Two factory cautions are easy to miss during major repair work. The B20A2 engine-mount bolts have a specified tightening order; getting that sequence wrong can twist the bushings, produce noise and vibration, and shorten bushing life. The power-steering section also warns that substituting ATF or another manufacturer's fluid for the specified Honda fluid can damage the system.

Fuel-system pressure, ALB hydraulics, refrigerant service, vehicle lifting, and rotating engine or transmission assemblies require normal shop controls and the specified test equipment. Use the model-identification pages, safety notices, and year-specific supplement before beginning repair work.
