Toyota Manual for Tarago Townace, Liteace Vans 1982–1989

• 4Y-E engine repair: Engine removal and installation, cylinder-head overhaul, timing-chain and camshaft service, and crankshaft, piston, and bearing inspection.
• TCCS fuel injection and Electronic Spark Advance: Blink-code diagnosis, ECU connector tests, fuel-pressure checks, and injector testing for the electronically controlled gasoline engine.
• G53 manual transmission and clutch: Gearbox disassembly, synchronizer and shaft inspection, reassembly, shift-cable adjustment, and clutch hydraulic service.
• A45DL and A45DF automatic transmissions: Stall, time-lag, and hydraulic-pressure tests, plus valve-body service and internal clutch, brake, and oil-pump overhaul.
• 4WD transfer and axle assemblies: Transfer-case teardown, electrical and vacuum shift diagnosis, front hub service, and differential inspection and adjustment.
• Brakes and steering: Load Sensing Proportioning and By-pass Valve testing, brake hydraulic repair, and overhaul procedures for steering racks, power-steering pumps, and the separate steering bevel-gear housing.
• Body electrical troubleshooting: Wiring diagrams, connector views, and component tests for lighting, instruments, power accessories, and cruise control.

This 1,021-page scanned PDF contains the 1987 Toyota Van Repair Manual, covering 4Y-E gasoline-engine applications with separate 2WD and 4WD procedures. It is a vehicle repair reference, not a collection of carbureted Y-series and C-series diesel engine manuals.

Chassis-specific information distinguishes YR22/YR31/YR32 from YR29 in the parking-brake data. The 4WD alignment section separately identifies YR31LG and YR32LV, helping match the specifications to the vehicle configuration.

Engine and fuel-system repair details

The valve-train section distinguishes Toyota- and GM-type hydraulic lifters, with different bleeding methods and leak-down testing. Toyota-type lifter service references SST 09276-71010. Fuel-pressure testing identifies SST 09268-45011, while the fuel-system chapter also covers residual-pressure checks and diagnosis of the cold-start injector and its time switch.

The ESA System Circuit and ECU terminal-reference tables support electrical fault tracing. Emission-control coverage extends to the EGR vacuum modulator, evaporative canister, and PCV system. Cooling-system pressure checks, lubrication-system inspection, starter testing, and alternator repair have their own sections.

The cylinder-head chapter includes a specific warning about bolt-removal order: an incorrect sequence can warp or crack the head.

Automatic transmission and 4WD diagnosis

The Automatic Shift Diagram relates shifting behavior to throttle opening and vehicle speed. Valve-body sections provide check-ball locations and spring-identification tables, while the overdrive-control information distinguishes driveline configurations. Hydraulic testing references SST 09992-00093.

Bench procedures extend beyond external adjustments to the overdrive assembly, planetary components, and one-way clutches. A clutch-service caution specifically addresses friction-disc damage from high-pressure compressed air.

For electrically shifted transfer systems, the Electronic Control Circuit accompanies troubleshooting for the control computer, speed signals, vacuum switching valves, and actuator. Manual free-wheeling hubs and automatic locking hubs receive separate service procedures rather than a single generic treatment.

Suspension, body, and accessory work

Front suspension coverage separates 2WD and 4WD alignment and torsion-bar adjustments. Rear suspension chapters address both four-link coil-spring and leaf-spring layouts. Differential repair includes bearing-preload adjustment, selective shimming, backlash checks, and tooth-contact evaluation.

Body procedures cover sliding-door rollers and latches, window mechanisms, glass replacement, and roof-opening assemblies. Body-dimension drawings distinguish wagon, van, and 4WD configurations.

The Cruise Control System wiring diagram is paired with actuator, cancellation-switch, and computer-circuit testing. Other electrical sections provide switch and relay checks, instrument fault tracing, and rear-window defogger diagnosis.

Original R-12 air conditioning

The air-conditioning chapter documents R-12 single- and dual-system configurations, with separate 2WD and 4WD Air Conditioning System Circuit diagrams. Manifold-gauge diagnostic charts address refrigerant-system faults, while performance-test information supports evaluation of cooling operation.

Component procedures cover front and rear evaporators, expansion valves, compressor shaft seals, and magnetic-clutch service. The refrigerator unit also has dedicated service and control-system information.

Specifications and special-tool references

Reference sections provide component-specific torque tables, standard dimensions and service limits, bearing-preload specifications, selective-fit shim data, and electrical test values. Fluid tables distinguish drain-and-refill quantities from dry-fill requirements and account for driveline and rear-heater configurations.

Dedicated special-service-tool and service-material tables identify equipment and sealers by application. These references accompany the individual repair chapters rather than reducing different assemblies to one set of general specifications.

Use appropriate protective equipment for pressurized fuel and refrigerant systems, and secure support for heavy drivetrain components; brake work requires the applicable inspection and safety precautions.
