Engine Overhaul, PGM-FI Diagnosis and Transaxle Service

The following highlights are a selection of the contents. Other topics include towing provisions and the radio’s theft-protection code system.

• Engine repair: Step-by-step cylinder-head and engine-block procedures, valve-train inspection, timing-belt service, lubrication-system repair, and cooling-system tests.

• PGM-FI diagnosis: Self-diagnostics, ECM troubleshooting, fuel-delivery tests, sensor-circuit checks, idle-control diagnosis, emissions systems, and B18C1 VTEC troubleshooting.

• Manual drivetrain: Clutch hydraulics and friction components, Y80 transmission disassembly, shaft and synchro inspection, differential setup, and driveshaft service.

• Automatic transmission: MP7A electrical and hydraulic diagnosis, stall-speed and pressure tests, valve-body repair, clutch-pack work, and cooler flushing.

• Steering, suspension and brakes: Power-steering pump and gearbox repair, wheel alignment, wheel-bearing replacement, disc-brake service, and ABS fault diagnosis.

• Body and climate control: Body panels, glass and interior trim, heater diagnosis, evaporator service, compressor-clutch work, and refrigerant-system testing.

• Electrical systems: Wiring diagrams, connector identification, starting and charging tests, lighting, gauges, interlocks, power accessories, cruise control, and SRS diagnosis.

Suited to mechanics familiar with standard workshop practices and equipped for component measurement, electrical testing, and the special-tool procedures described in the manual.

Engine, Valve Train and Cooling

The 23-section layout separates general information, specifications, and scheduled maintenance from the mechanical and electrical repair sections. Exploded-view indexes provide disassembly references, bolt torques, thread sizes, and links to the corresponding procedures.

Separate B18B1 and B18C1 cylinder-head sections address valve seals, guides and seats, camshafts, rocker arms, and engine-specific tightening procedures. Engine-block coverage extends to pistons and rings, crankshaft inspection, bearing selection, and oil-seal installation.

Timing-belt limitation: The B18B1 installation procedure is incomplete in this PDF: printed page 6-13 is omitted between PDF pp. 75 and 76.

Lubrication coverage includes oil-pressure testing and oil-pump inspection and repair. Cooling procedures cover radiator and cap testing, coolant refilling and bleeding, thermostat testing, and water-pump replacement. Intake-manifold and exhaust-system service is covered separately.

Component cautions address cylinder-head damage during hot-engine disassembly and differential oil-seal or intermediate-shaft dust-seal damage during driveshaft removal.

Fuel Delivery, Engine Inputs and VTEC

The PGM-FI section goes beyond routine tune-up information. It distinguishes ECM faults, fuel-pressure problems, injector and fuel-pump faults, and input-circuit problems involving MAP, ECT, TPS, IAT, TDC/CKP/CYP, and vehicle-speed signals.

B18C1 coverage adds knock-sensor and VTEC checks. Idle-control circuits and emission-control hardware have their own descriptions and troubleshooting material.

Symptom charts and component-specific tests help distinguish fuel-delivery faults from sensor or wiring faults before choosing a repair.

Clutch, Transmissions and Differentials

Y80 manual transmission: Coverage extends from the clutch disc, pressure plate, flywheel, release bearing, and hydraulic controls into housing disassembly, shafts, gears, synchros, bearings, and thrust-shim adjustment.

MP7A automatic transmission: Hydraulic-flow explanations and lock-up operation accompany TCM input checks and solenoid diagnosis. Internal repair material covers the valve body, clutch packs, oil pump, shafts, bearings, and torque converter, followed by installation, shift-cable adjustment, and cooler-flushing procedures.

The manual warns that incorrect main ball-bearing replacement can damage the torque-converter housing and oil pump, potentially causing pump seizure.

Separate differential sections distinguish manual-transmission engine variants from the automatic-transmission unit. Backlash, side clearance, bearing replacement, and preload adjustment are addressed where applicable; driveshaft coverage includes joint and boot service.

Chassis, ABS and Climate Control

Power rack-and-pinion steering coverage includes pump testing and overhaul, gearbox repair, and adjustment. Suspension material includes wheel bearings, ball joints, bushings, dampers, and alignment.

Four-wheel disc-brake procedures are supplemented by ABS circuit diagrams, terminal arrangements, diagnostic-code charts, wheel-sensor checks, pump and pressure-switch diagnosis, and modulator function tests.

Body coverage includes panels, door glass, window mechanisms, and interior trim. Heater and HFC-134a A/C sections cover circuit diagnosis, performance and pressure-test charts, recovery, evacuation, leak testing, and charging. Refrigerant-oil specifications identify ND-OIL8, P/N 38899-PR7-A01.

A/C limitation: Printed pages 22-30–31, covering compressor replacement, are omitted. Compressor-clutch inspection and overhaul remain included.

Circuit Diagrams, Tools and Service Precautions

Diagram examples include the VTEC Pressure Switch Troubleshooting Flowchart, Automatic Transmission Hydraulic Flow, and the A/T Circuit Diagram. Heater, A/C, and SRS circuit diagrams cover additional systems.

Section 23 provides schematic symbols, relay and control-unit locations, connector identification, harness routing, and power and ground distribution.

Special-tool tables identify the 07PAZ-0010100 SCS Short Connector, 07406-0040001 Fuel Pressure Gauge, 07406-0020003 A/T Oil Pressure Gauge Set, 07JGG-001010A Belt Tension Gauge, and 07HAZ-SG00400 SRS Deployment Tool.

SRS, pressurized fuel and transmission circuits, and refrigerant service require the specified precautions and equipment. The SRS section carries Honda’s instruction that SRS service be performed by an authorized Acura dealer.

A Preview of Fuel-Pressure and Valve-Guide Specifications

Fuel-pressure testing at idle, with the regulator vacuum hose disconnected and pinched, specifies 275–324 kPa for the B18B1 and 329–378 kPa for the B18C1.

Cylinder-head inspection tables distinguish standard intake valve stem-to-guide clearance by engine: 0.02–0.05 mm for the B18B1 and 0.025–0.055 mm for the B18C1. Separate service limits accompany these standard dimensions.
