Pontiac Montana/SV6 2005–2009 Service & Owner Manual Set (P/N 06MONTANASV6 A)

The owner manuals explain vehicle operation, routine checks and scheduled maintenance. The separate workshop chapters support diagnosis, component replacement and internal powertrain work.

Coverage varies by publication. The LZ9 engine chapter is labeled Terraza/Uplander, and both standalone wiring sets are labeled Chevrolet Uplander. The Steyr chapter describes an LA1 3400 V6/VIN E application. The three Montana-specific 2009 extracts cover disc brakes, exterior trim, and bumpers/fascias.

Text Search, Bookmarks and File Contents

Search and chapter access: Eleven PDFs have searchable text; the other 40 do not. The four owner manuals have chapter bookmarks. Three 2009 repair extracts have numbered bookmarks, while 44 PDFs have none. Small wiring labels on the checked pages require zooming.

The RAR archive contains 51 printable PDFs totaling 8,148 pages: 1,976 pages in the four owner manuals and 6,172 pages in service and reference files. These totals include the owner manuals’ contents, indexes and 18 note pages.

Engine, Driveline and Vehicle-System Coverage

These are selected content highlights. Further topics include horn circuits and passenger-compartment air-filter replacement.

• Engine mechanical: LX9 mechanical diagnosis, engine removal, cylinder-head service, timing-chain work, internal inspection and reassembly, plus a separate LZ9 engine chapter.

• Transmission and driveline: 4T65-E symptom diagnosis and overhaul, rear-axle service, locking/limited-slip components, propeller shafts, wheel drive shafts and a separate Steyr transfer-case chapter.

• Brakes and chassis: Disc and hydraulic brake diagnosis, bleeding procedures, parking-brake service, power steering, suspension repairs and automatic level-control testing.

• Electrical and body controls: Vehicle DTC checks, starting and charging diagnosis, component locations, power sliding doors, windows, mirrors, keyless entry and lighting circuits.

• Climate control: A/C performance and leak testing, pressure-zone diagnosis, compressor replacement, heater-core work and front and auxiliary HVAC component service.

• Owner information: Seats, safety belts, child restraints, airbags, keys and theft deterrence, instrument-panel controls, DIC messages, audio operation, towing and maintenance schedules.

The owner guides suit everyday vehicle use and routine checks; the workshop chapters suit technicians and experienced DIY owners equipped for scan-tool diagnosis, precision measurement and component overhaul.

Mechanical Diagnosis and Internal Repair

The LX9 chapter separates misfire, engine-noise, oil-consumption and coolant-related symptoms. Compression and oil-pressure tests support fault assessment before major disassembly. Internal repair coverage extends to crankshaft bearings, pistons, cylinder heads and the oil pump, with related inspection specifications and special-tool references.

4T65-E fault isolation: Troubleshooting tables distinguish delayed engagement, harsh shifts, slipping, no-drive/no-reverse conditions and torque-converter clutch concerns. Scan-tool data and internal mode-switch checks help separate electrical input problems from mechanical faults before the overhaul procedures are selected.

The overhaul chapter provides disassembled views and procedures for the valve body, pump, clutch assemblies, servos and differential. Its build tables cover several GM applications, so the transmission configuration matters when selecting specifications.

AWD references: Rear-axle material includes an All-Wheel Drive Schematic. The separate Steyr chapter covers internal disassembly, inspection and assembly with holding fixture J 44755; its cautions identify sealing-surface damage as a risk during case separation.

Electrical Diagnosis, Doors and HVAC

The vehicle DTC guide prioritizes serial-data communication faults before individual system-code diagnosis. Starting and Charging Schematics accompany the engine-electrical tests, while component-location references identify modules, relays, grounds and connectors.

Power Sliding Door (PSD) Schematics support door-system fault tracing. The door chapters also address motor/clutch circuits, latches, contact plates, window mechanisms and alignment.

HVAC coverage goes beyond control operation: it includes refrigerant leak testing, performance assessment, pressure-zone diagnosis and component replacement. Front and auxiliary systems have separate procedures where their layouts differ.

Brakes, Suspension and Restraints

The brake chapters distinguish FWD and AWD disc-brake specifications and include hydraulic diagnosis, master-cylinder service and bleeding procedures. Brake Warning System Schematics support electrical checks. The repair instructions also flag flexible-hose damage and possible fluid leakage when a removed caliper’s weight loads the hose.

Suspension and steering chapters address struts, control arms, hubs, steering gear and automatic level control. Seat coverage includes Driver Seat Schematics and Sit-N-Lift components, alongside separate SIR diagnosis and service information.

Electrical, restraint, brake and vehicle-lifting work requires the relevant safety procedures, suitable tools and appropriate training.

Owner Controls and Routine Care

The owner guides explain traction control and StabiliTrak where equipped, warning messages, towing limits and scheduled maintenance. Their DIC explanations connect displayed alerts with the corresponding owner checks or service information.

Fluid capacities and operating instructions remain specific to the vehicle and publication. The earlier Montana owner guide and the Montana SV6 guide should be matched to their respective models.

Preview: Valve-Seat Widths and AWD Rotor Limits

For the LX9 cylinder head, the specification table lists intake valve-seat widths of 1.55–1.80 mm and exhaust widths of 1.70–2.0 mm. These specifications accompany the cylinder-head inspection and repair material.

For the 2005 shared-model AWD front disc brakes, the table specifies 30.0 mm new rotor thickness and 27.0 mm discard thickness. FWD specifications are listed separately, so these figures are specific to the stated brake configuration.
