2000 Jeep Grand Cherokee WJ 4.0L and 4.7L OEM Service Manual (P/N 81-370-0047)

This 2,034-page PDF set brings together the official DaimlerChrysler 2000 WJ Jeep Grand Cherokee Service Manual, Publication No. 81-370-0047, in 55 section files. Coverage includes the 4.0L inline-six, 4.7L V8, and 3.1L VM turbo diesel, with LHD/RHD and built-up-export versus North American distinctions where applicable. Its repair depth and tooling requirements make it best suited to professional technicians and experienced repairers equipped for scan-tool diagnosis, drivetrain measurement, refrigerant service, and heavy-component handling.

Factory Repair Coverage

• Maintenance schedules: Provides normal and severe-use Schedule A/B service intervals, including dusty operation, extended idling, trailer towing, sustained high-speed use, off-road driving, and post-off-road underbody checks.

• Engine repair: Covers compression and cylinder-leakage testing, oil-pressure diagnosis, engine removal and installation, cylinder-head and valvetrain work, timing-system service, piston and bearing fitting, oil-pump service, and block inspection. The 4.7L material distinguishes early- and late-build piston and ring designs; the 3.1L section identifies engine model code 73B and its serial-number location.

• Fuel, ignition, and emissions systems: Details gasoline fuel-pump module, filter/regulator, tank, rail, injector, throttle-body, sensor, coil-rail, and coil-on-plug service, supported by pressure, capacity, leak-down, amperage, and injector tests. Separate Federal and California catalyst and oxygen-sensor layouts are shown for the 4.0L and 4.7L engines. Exhaust-pipe, heat-shield, muffler, and tailpipe repair sits alongside EVAP monitoring, OBD operation, and DTC charts.

• 3.1L diesel procedures: Includes the fuel filter/water separator, heater, electronically managed injection pump, high-pressure lines, injectors, needle-movement sensor, air bleeding, pump timing, turbocharger, charge-air cooler, glow system, diesel ECM codes, and diesel-specific cooling, charging, steering, HVAC, and maintenance information.

• Transmission, transfer case, and axle repair: The 44RE section provides road testing, hydraulic pressure testing, transmission removal, valve-body and clutch/servo disassembly, overdrive-unit overhaul, band and cable adjustments, hydraulic schematics, and final specifications. NV247 removal and installation is included. Axle coverage spans the 186 FBI, 198 RBI, and 226 RBA assemblies, including standard, Trac-Lok, and Vari-Lok differentials, pinion-depth setup, bearing preload, backlash, and contact-pattern analysis.

• Brakes, steering, suspension, and body: Covers wheel alignment, suspension diagnosis, power-steering flow and pressure checks, base and ABS brake bleeding, CAB/HCU and wheel-speed-sensor service, panel and glass repair, power-sunroof work, frame measurements, and body-opening dimensions. The HVAC chapters add manual and Automatic Zone Control diagnosis plus R-134a leak testing, recovery, evacuation, and charging procedures.

• Electrical diagnosis: Group 8W supplies 556 pages of wiring diagrams, connector pin-outs, connector and splice locations, ground distribution, and wiring-repair procedures. System coverage includes starting and charging, fuel/ignition, transmission controls, ABS, airbags, body control, lighting, trailer tow, power accessories, Sentry Key security, memory seats, and overhead-console/compass programming and calibration.

Diagrams, Specifications, and Special Tools

Named visual references include the 4.7L Engine Oil Lubrication System, 44RE Hydraulic Flow During Full Throttle 3-2 Downshift, separate 4.0L and 4.7L Catalytic Converter and O2 Sensor Configuration—California and Federal Emissions views, Diesel Engine Connectors, and Transmission Connections for the gasoline powertrains.

Component-specific torque charts appear throughout the repair groups, backed by fluid-capacity data, pressure-test specifications, clearance and wear limits, alignment values, axle setup data, brake-rotor limits, electrical test values, and A/C performance charts. Referenced equipment includes the DRB III scan tool, VM.1011 injection-pump timing adapter, VM.1012B injector socket, Pinion Gauge Set 6774, D-348/8107 axle setup tooling, and the 6227 transmission spring compressor and alignment shaft.

The manual flags repair traps that matter. Over-crushing an axle pinion collapsible spacer invalidates the preload; backing off the nut is not an acceptable correction. During 44RE oil-pump installation, leaving the front band tight can damage the pump seal rings.

Scope and Safety Notes

The supplied set contains the diesel 44RE and NV247 material, but not the separate gasoline Group 21 repair chapter for the 42RE and 45RFE transmissions. Many scan-tool routines also direct the technician to separate Powertrain, Body, or Chassis Diagnostic Procedures manuals; those companion publications are not part of this set.

Airbag service is expressly restricted to Chrysler-trained and authorized dealer technicians. Refrigerant work, high-pressure diesel-fuel testing, brake repair, and under-vehicle procedures require the specified recovery, test, lifting, and support equipment.
