2002–2006 Range Rover L322 TD 6 3.0L, V8 4.4L Diesel Workshop Manual (P/N LRL0477NAS)

• Document set: Land Rover factory workshop documentation for the Range Rover L322/LM, supplied as a 1,747-page PDF set — Service Procedures, Land Rover publication code LRL0477NAS, 6th Edition, ©2003, NAS (North American Specification), labeled “2002MY ON” (938 pages); and System Description and Operation, Land Rover publication code LRL0424ENG, 2nd Edition, ©2002, labeled “2002MY” (809 pages).
• Powertrain coverage: Explains the Td6 diesel and V8 gasoline engines, their engine-management and fuel-delivery systems, the GM 5L40-E and ZF 5HP24/5HP24A automatic transmissions, and the New Venture Gear NV225 two-speed transfer box.
• V8 factory repair work: Covers engine removal, cylinder-head gasket replacement, variable camshaft control service, timing-chain and guide work, oil-pump repair, and internal overhaul procedures for pistons, connecting-rod bearings, crankshaft/main bearings, and cylinder heads.
• Drivetrain and chassis procedures: Details transmission fluid service and valve-body replacement, transfer-box removal and seal work, propeller shafts and CV shafts, differential removal and sealing, steering pressure tests and alignment, air-suspension depressurization and calibration, brake bleeding, disc inspection, and DSC/ABS component repair.
• Body, HVAC, and restraint work: Provides body dimensions and panel-gap data, replacement-panel and welding procedures, structural sealing and cavity-wax guidance, leak detection, refrigerant recovery and recharge, heater/air-conditioning repair, and SRS component replacement and deployment procedures.
• Controls and diagnostics: Documents Bosch ME 7.2, the Body Control Unit, communication data buses, security and immobilization, lighting, windows, navigation, parking aid, tire-pressure monitoring, and instrument systems, with TestBook/T4 requirements for diagnosis, ECU configuration, adaptation reset, initialization, and calibration.
• Factory reference data: Supplies component-specific torque tables, V8 valve-train and crankshaft inspection limits, brake-disc wear and runout specifications, transmission/transfer/differential fluid data, body dimensions, electrical connector pin details, SRO numbers, and special-tool references tied to the covered repair operations.

Technical Documentation and System Coverage

The two volumes do different jobs. The System Description and Operation manual explains how the 3.0-liter inline-six Td6 common-rail diesel and 4.4-liter V8 gasoline systems are built and controlled. It traces air, fuel, lubrication, cooling, emissions, CAN-bus communication, and power flow through the drivetrain. The Service Procedures manual then provides workshop operations, inspection criteria, assembly notes, and tooling for the repairs covered by its NAS edition.

Variant identification is unusually detailed. The text separates NAS from all-except-NAS fuel-system layouts, LHD and RHD steering and HVAC arrangements, low-line and high-line climate control, halogen and Xenon ride-height sensor configurations, fuel-burning-heater installations, and Japan-specific navigation hardware. The air-suspension chapter also records the production change at VIN 106310, distinguishing the earlier and later pressure-relief arrangements and the related control strategy.

Coverage is not identical for both engines. LRL0424ENG describes the Td6 and V8 powertrains, including the GM 5L40-E used with Td6 and the ZF 5HP24 used with V8. LRL0477NAS contains the full V8 engine repair and overhaul chapter, plus ZF fluid, selector, seal, cooler, valve-body, and unit-removal procedures. It retains Td6 maintenance and several Td6-specific chassis operations, but it does not provide a parallel Td6 internal-engine repair chapter. GM 5L40-E coverage is descriptive and diagnostic rather than a workshop overhaul, and neither automatic-transmission section contains a complete internal rebuild sequence. The separate full Electrical Circuit Diagrams publication is not included in this two-PDF set.

Diagrams, Specifications, and Shop-Level Detail

Useful visual references include the Td6 Fuel System Schematic, Transfer Box Exploded View, ZF 5HP24 Sectional View, Dynamic Stability Control System Control Diagram, Communication Data Buses Control Diagram, and SRS Control Diagram. Component-location drawings and connector/pin information add the context needed for subsystem diagnosis.

Factory tool callouts are carried directly into the repair procedures. Examples include the LRT-12-223 and LRT-12-227 V8 timing fixtures, LRT-19-006 fuel-system test equipment, and LRT-60-033 hub-bearing tooling. Many electronic repairs specify TestBook/T4 before disconnection or replacement, followed by the required configuration, adaptation, or calibration work.

The cautions are often as useful as the tables. The V8 head-gasket procedures warn that oil or coolant left in the head-bolt holes can damage the cylinder block during tightening. The NV225 ratio-control actuator section warns that rotating or withdrawing its lead screw can cause internal transfer-box damage. Fuel, brake, refrigerant, air-suspension, SRS, and heavy drivetrain repair should be handled with the specified isolation, support, recovery, and diagnostic equipment.
