2001–2002 Subaru Legacy & Outback OEM Service Manual (P/N G2281GE)

• Contains the Fuji Heavy Industries 2001 Legacy Service Manual—Supplement for 6-Cylinder Engine Model, identified by factory document code G2281GE and applied to BE-series sedans and BH-series station wagons/Outback from 2001MY.
• Supplied as a 1,130-page PDF set in 24 files: maintenance, rear suspension, H6 engine systems, engine diagnostics, and nine Wiring System files.
• Covers 3.0 L H6 repair from compression, idle-speed, ignition-timing, and valve-clearance checks through engine removal, timing-chain service, camshafts, cylinder heads, cylinder-block inspection, reassembly, and engine-noise diagnosis.
• Details H6 fuel injection, induction, emission control, exhaust, cooling, lubrication, ignition, starting, and charging work, with component removal and installation, disassembly, inspection, testing, and system troubleshooting.
• Provides 327 pages across two Engine Diagnostics files, covering ECM/TCM input and output data, OBD-II and Subaru Select Monitor functions, starting-failure testing, memory and inspection modes, and more than 100 DTC entries with fault trees or cross-references.
• Treats rear suspension as a dedicated repair section, with sedan, wagon, and Outback alignment; stabilizer, rear arm, upper/front/rear links, shock absorbers, sub-frame, bushing service, and diagnostic tables.
• Adds 362 pages across nine Wiring System files for power and grounds, H6 engine electrical and A/T control, radiator fans, Vehicle Dynamic Control, air conditioning, and LHD/RHD connector and harness locations.

Factory H6 Repair Depth

The mechanical chapters cover engine removal and installation, mounting, and preparation for overhaul. Internal service material then moves through crankshaft pulley and sprocket work, front and rear chain covers, timing-chain routing and indexing, camshaft sprockets, camshafts, cylinder-head assemblies, and cylinder-block inspection. Valve-clearance service includes H6 shim-replacement tooling and selection data. Separate troubleshooting chapters address engine-condition faults and abnormal noise.

Factory tool tables identify application-specific equipment for these jobs. Examples include the 18232AA000 Engine Stand, 18231AA000 Camshaft Sprocket Wrench, 18252AA000 Crankshaft Socket, 18329AA000 Shim Replacer Assembly, 927380002 wheel-alignment adapter, and 20099AE-series rear-suspension bushing installers and removers. Component-specific torque tables, fluid capacities, inspection limits, clearances, and adjustment specifications appear with the related repair procedures.

Fuel-system coverage reaches from the throttle body, intake manifold, injectors, pressure checks, pump, tank, level sensors, filter, and evaporative lines to the ECM, relays, oxygen and air/fuel sensors, and engine-control inputs. Separate sections handle catalytic converters, EGR and purge controls, cooling fans, water pump, thermostat, radiator, oil pump and relief valve, starter, generator, and battery.

Diagnostics, Wiring, and Rear Chassis

The diagnostic material is arranged for circuit-level fault isolation. It includes the technician interview checklist, electrical-component locations, ECM and TCM data, Data Link Connector information, scan-tool procedures, DTC retrieval and clearing, compulsory-valve operation, inspection mode, starting-failure testing, and code-specific diagnostic charts.

Named visual references include the H6 Timing Chain Assembly views, Rear Suspension component and alignment drawings, H6 Engine Electrical System schematic, H6 A/T Control System schematic, Radiator Fan System schematic, and Vehicle Dynamic Control System schematic. Wiring variants are split by LHD/RHD and H4/H6, with OBD/non-OBD, Outback, VDC, and pneumatic-suspension branches where applicable. Harness-location drawings cover the front, bulkhead, engine/transmission, instrument panel, rear body, doors, trunk, and rear gate.

Coverage to Check Before Ordering

The identification and specification chapters include Legacy 2.0 L and 2.5 L sedan/wagon data and Outback 2.5 L and 3.0 L data, along with body, engine, transmission, and rear-differential code decoding. The VIN section recognizes 2001MY and 2002MY model-year identifiers. The cover and applied-model statement identify this publication as the 2001 H6 supplement for BE/BH vehicles from 2001MY. Its dedicated engine repair chapters are for the 3.0 L six-cylinder engine; the 2.0 L and 2.5 L references do not make it a full H4 engine repair manual.

Subaru directs technicians to the separate Automatic Transmission Service Manual, Pub. No. G0853ZE. This set includes A/T control wiring, TCM data, transmission-related DTC references, maintenance information, and fluid specifications, but not that manual's full internal automatic-transmission repair coverage.

The factory cautions flag two costly errors: a wrong-spec ECM can damage the fuel-injection system, while forcing an oxygen sensor from a cold exhaust can damage the pipe. Timing-chain work also depends on correct sprocket indexing, chain-mark alignment, and tensioner handling.

This factory information is written for experienced technicians and owners. Engine lifting, fuel-system pressure relief, hot exhaust work, SRS circuits, and suspension service require proper shop equipment and established safety procedures; use a qualified technician when the repair exceeds your training or tools.
