Acura Integra 1998 Service Manual Set (P/N 61ST705)

Use the base manual for mechanical service and the electrical manual to trace the circuit for the applicable model year. The 2001 supplement adds revised specifications, maintenance schedules, and a coolant refilling and bleeding procedure that refers back to the base manual for items it omits.

Text Search and Scan Coverage

Search and diagram detail: The PDF is partially searchable. The opening identification and specification pages and the Type R insert are image-only. Use the printed indexes and section tabs for navigation, as the file has no PDF bookmarks. Small wire-color codes and connector labels are easier to read at higher zoom. A few labels in the base manual’s SRS schematic are degraded in the scan.

The download is one printable English-language PDF with 1,680 pages, including the nine-page Type R insert and the scanned covers of the electrical manual and supplement. The base and electrical scans contain fewer pages than the page counts printed in those publications.

B-Series Repair, Transaxle Overhaul, and Circuit Diagnosis

The following selected topics show the scope of the set. The manuals also cover normal and severe maintenance schedules and moonroof service.

• Engine and cooling: Engine removal and installation, cylinder head and timing belt service, crankshaft and bearing inspection, oil pump overhaul, and cooling system pressure tests.
• VTEC and PGM-FI: VTEC solenoid, pressure switch, and rocker arm checks, plus ECM terminal references and fault charts for misfires, fuel delivery, oxygen sensors, and EVAP.
• Manual transaxle: Clutch hydraulics and flywheel service, shaft and synchronizer inspection, shift fork clearances, driveshaft service, and B18C5 limited-slip differential repair.
• Automatic transaxle: Road and stall tests, hydraulic pressure checks, solenoid and speed sensor diagnosis, and overhaul procedures for valve bodies, clutch packs, and shafts.
• Chassis and body: Power steering pump and rack repair, wheel alignment, hub and bearing service, brake hydraulics, ABS modulator and sensor diagnosis, and body hardware and glass service.
• Electrical and climate systems: Power and ground distribution, starting and charging circuits, SRS fault charts, heater diagnosis, and A/C leak testing and compressor clutch service.

The set is suited to technicians and experienced owners familiar with shop procedures and equipped for lifting, measuring, and electrical diagnosis. The base manual assumes that background. It directs airbag service to an authorized Acura dealer and warns against probing yellow SRS wiring.

Fitment and Overhaul References

The base manual separates B18B1 cylinder head procedures from B18C1 and B18C5 VTEC work. Its exploded views, torque callouts, and standard-versus-service-limit tables help identify which measurements apply during teardown. Tool references include the SCS Service Connector 07PAZ-0010100, VTEC Air Stopper 07LAJ-PR3020A, A/T Pressure Gauge Set 07406-0020400, and P/S Pressure Gauge 07406-0010001.

The driveshaft procedure flags two risks during removal: separation of the inboard joint and damage to the differential or intermediate shaft seal. The automatic transaxle section also limits stall-test duration to prevent transmission damage.

Circuit Tracing by Model Year

The electrical manual pairs schematics with fuse and relay data, component photos, connector cavity numbers, and harness routing. Its ground index and shared-connector charts help trace several symptoms to a common ground or connector. The Type R insert adds ECM/PCM connector A, B, and C terminal layouts and B18C1/B18C5 engine harness references.

Valve Clearance and VTEC Test Examples

The B18B1 valve adjustment procedure specifies 0.08–0.12 mm intake clearance with the cylinder head below 100°F (38°C).

For the B18C1 and B18C5, the VTEC solenoid inspection specifies 14–30 Ω between the solenoid terminal and body ground with the connector disconnected.
