Jeep Grand Cherokee WJ 2000 Service Manual (P/N 81-370-0047)

This official DaimlerChrysler 2000 WJ Jeep Grand Cherokee Service Manual (P/N 81-370-0047) covers 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.

PDF Text Search, Bookmarks, and Diagram Detail

Search and navigation: Text search is available in the repair chapters, but many wiring diagrams and connector pin-out pages have no searchable text. Embedded bookmarks navigate the chapter files; the welcome screen and group locator have no bookmarks. Small wiring and pin-out labels require zooming.

The ZIP contains 2,034 pages across 55 printable PDFs. This total already includes the one-page welcome screen, the one-page group locator, 40 blank pages, and service revisions integrated into the chapter files.

Engine, Drivetrain, and Vehicle Electrical Service

The following is a selection of the contents, with tire-and-wheel service and heated-seat diagnosis among the other covered topics.

• Maintenance schedules: Normal and severe-use Schedule A/B intervals cover dusty operation, extended idling, trailer towing, sustained high-speed use, off-road driving, and post-off-road inspections.

• Engine repair: Step-by-step procedures cover engine removal and installation, cylinder-head and valvetrain work, timing-system service, piston and bearing fitting, oil-pump service, and block inspection.

• Fuel, ignition, and emissions: Gasoline fuel-delivery and ignition service includes pressure, capacity, leak-down, amperage, and injector testing, with Federal and California emissions distinctions.

• Diesel systems: Electronically managed injection-pump service and timing, turbocharger and charge-air-cooler work, and glow-system diagnosis are covered in dedicated diesel sections.

• Drivetrain repair: The 44RE chapter includes road and hydraulic testing, valve-body and clutch/servo disassembly, overdrive overhaul, band and cable adjustments, and hydraulic schematics.

• Chassis and brakes: Wheel alignment, suspension diagnosis, power-steering flow and pressure checks, base and ABS bleeding, and CAB/HCU and wheel-speed-sensor service are included.

• Electrical diagnosis: Wiring diagrams, connector pin-outs, ground distribution, connector and splice locations, and wiring-repair procedures support circuit testing and fault tracing.

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.

Engine Diagnosis and Fuel-System Variants

Mechanical diagnosis covers compression, cylinder leakage, and oil pressure. The 4.7L material distinguishes early- and late-build piston and ring designs, helping match replacement rings to the documented piston design.

Gasoline systems: Procedures cover the fuel-pump module, filter/regulator, tank, rail, injectors, throttle body, sensors, coil rail, and coil-on-plug ignition. Separate Federal and California catalytic-converter and oxygen-sensor layouts are shown for both gasoline engines.

Exhaust-pipe, heat-shield, muffler, and tailpipe repair sits alongside EVAP monitoring, OBD operation, and DTC charts.

Diesel-specific work: Additional procedures address the fuel filter/water separator, fuel heater, high-pressure lines, injectors, needle-movement sensor, air bleeding, and diesel ECM codes. Dedicated material also covers diesel cooling, charging, steering, HVAC, and maintenance.

Cooling chapters include leak and coolant-flow checks, thermostat testing, water-pump and radiator replacement, and coolant draining and filling.

Transmission Scope and Axle Setup

Gasoline transmission limitation: The supplied files contain the diesel 44RE chapter and NV247 removal and installation procedures, but not the separate gasoline Group 21 repair chapter for the 42RE and 45RFE transmissions. Specifications and electrical references to those gasoline transmissions do not provide their internal repair procedures.

Axle coverage spans the 186 FBI, 198 RBI, and 226 RBA assemblies, including standard, Trac-Lok, and Vari-Lok configurations. Pinion-depth setup, bearing preload, backlash, and contact-pattern analysis are covered.

Over-crushing an axle pinion collapsible spacer makes it unsuitable for the specified 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.

Body Repair and Climate Control

Body procedures cover panels, stationary glass, 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.

Wiring References, Specifications, and Special Tools

Group 8W provides 556 pages of electrical documentation. 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.

Named visual references include the 4.7L Engine Oil Lubrication System, 44RE Hydraulic Flow During Full Throttle 3-2 Downshift, separate California and Federal Catalytic Converter and O2 Sensor Configuration views, Diesel Engine Connectors, and Transmission Connections for the gasoline powertrains. Connector views and location references allow a circuit to be followed from the schematic to its terminals and physical connections.

Component-specific torque charts are supported by fluid capacities, 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.

Many diagnostic routines refer to separate Powertrain, Body, or Chassis Diagnostic Procedures manuals. Those companion publications are not included.

Specialist Work and Safety

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.

A Preview of 4.0L Oil-Pump Inspection Clearances

For the 4.0L oil pump, the specification table lists radial gear-to-body clearance of 0.051–0.102 mm (0.002–0.004 in.).

Gear-end clearance measured with Plastigage is listed as 0.051–0.152 mm (0.002–0.006 in.). The table distinguishes this measurement from the separate feeler-gauge specification.
