Subaru Legacy & Outback 2013 Factory Service Manual (P/N G2490BE2-G2490BE7)

• Exact coverage: 2013MY Subaru Legacy and Outback models identified by factory codes BM***** and BR***** - sedan and wagon - with the non-turbo 2.5L H4DO and 3.6L H6DO engines. The manual is supplied as one 6,287-page PDF.
• Engine content covers removal and installation, overhaul preparation, compression and pressure testing, timing-chain service, camshaft and cam-carrier work, cylinder-head and cylinder-block repair, plus fuel, emissions, cooling, lubrication, ignition, and charging systems.
• Transmission coverage is configuration-specific: CVT or 6MT for 2.5L models and 5AT for 3.6L models. Procedures include assembly removal, internal disassembly and inspection, valve-body and differential service, CVT pulley and variator-chain work, clutch bleeding, road and stall tests, pressure testing, and learning control.
• Chassis sections detail wheel alignment, struts and links, hub bearings, drive shafts, T-type and VA-type rear differentials, transfer components, VDC/ABS, hydraulic brakes, electronic parking-brake diagnosis and emergency release, and power-steering repair.
• Factory diagnostics include Subaru Select Monitor functions, DTC and current-data charts, ECM/TCM and control-module I/O tables, CAN circuit checks, TPMS transmitter registration, occupant-detection rezeroing, EyeSight camera adjustment, and keyless/push-button-start diagnosis.
• Electrical reference material includes wiring diagrams for the engine electrical, CVT control, EyeSight, VDC, airbag, and occupant-detection systems, along with power and ground circuits, connector views, harness locations, exploded assemblies, torque tables, capacities, pressure-test data, inspection limits, clearances, and electrical test values.

Subaru states that the manual was prepared for service personnel and as guidance for experienced mechanics. It is best suited to users with established repair experience and access to appropriate lifting equipment, meters, scan functions, and special tools. This is factory workshop material, not a beginner-level maintenance guide.

Factory Repair Procedures and Special Tools

The engine volumes cover both scheduled service and internal repair. They document engine removal, timing-chain indexing, camshaft and cylinder-head work, cylinder-block disassembly, inspection, reassembly, and final checks for the H4DO and H6DO engines. Component illustrations identify sealing points, lubrication points, replacement parts, and tightening locations, while cross-references connect each repair to the related fuel, cooling, exhaust, and diagnostic section.

Preparation-tool tables identify Subaru tools by number, including the 18252AA000 crankshaft socket and 18355AA000 / 18334AA030 pulley-wrench set. Electronic testing and several setup procedures reference the Subaru Select Monitor III.

The Body volume adds refrigerant recovery, charging and leak testing, post-collision airbag inspection, seat-belt and pretensioner service, windows and mirrors, seats, locks, sunroof, trim, and exterior-panel removal. The Body Structure chapter directs reference-point, body-dimension, and structural collision-repair work to the separate Subaru Body Repair Manual; those procedures are not included in this PDF.

Subaru Diagnostics, Calibration, and Repair Cautions

Diagnostic chapters use symptom tables and branching test charts as well as fault-code lists. Depending on the system, they include live-data checks, communication tests, inspection modes, warning-light patterns, cancel codes, actuator or sequence-control checks, calibration, and module registration.

The H4 timing section warns that independently rotating the intake and exhaust camshafts with a timing chain removed can bring the valves together and bend the stems. Cam-carrier procedures also warn that excessive liquid gasket can enter a camshaft journal and cause engine seizure.

Before fuel, brake, SRS, HVAC, or electrical repair, follow the manual's system-specific fuel-pressure-relief, refrigerant-handling, battery-isolation, airbag, and lifting precautions.
