Primary Engine:
The VK Commodore was offered with a range of engines. The most common were Holden's own 3.3L (202 cubic inch) inline-six and a 4.2L (253 cubic inch) V8. Optional was the more powerful 5.0L (308 cubic inch) V8, often referred to as the 'Blue' or 'Red' motor depending on the specific era of the block. The manual would cover all these variations, including carburetion and injection systems where applicable for the later models.
Performance:
Performance varied significantly with engine choice. The 3.3L inline-six provided adequate power for everyday driving, while the V8 engines offered considerably more performance, with the 5.0L V8 being the performance flagship, particularly in models like the SS. Horsepower figures ranged from approximately 100-130 hp for the six-cylinder to 170-220 hp for the V8s, depending on exact specification and tuning.
Fuel System:
Primarily carbureted systems for the 3.3L inline-six and V8 engines, typically using Rochester Quadrajet or similar multi-point carburetors. Later models and specific performance variants might have featured electronic fuel injection (EFI), especially for the 5.0L V8 in the SS model, though carburetors were prevalent throughout most of the VK's production.
Engine Codes:
The manual would detail specifications for Holden's 'Red' and 'Blue' engine families, including specific codes for the 3.3L (RB33) and V8 variants (LC 4.2L, LF 5.0L). These codes are crucial for correct part identification and service procedures.
Cooling System:
Pressurized system with radiator, fan (mechanical or electric depending on model), thermostat, water pump, and coolant recovery tank. The manual covers draining, filling, bleeding, and troubleshooting. Radiator part numbers and capacities would be specified.
Torque Specifications:
Crucial torque specifications for cylinder head bolts, main bearing caps, connecting rod bolts, intake and exhaust manifolds, and various other engine components are provided to ensure proper assembly and prevent damage.
Ignition System:
Covers the distributor-based ignition system, including spark plug types and gap settings, ignition timing adjustment procedures, coil testing, and distributor maintenance. Points and condenser replacement on older variants may also be covered.
Compression Ratios:
Varies by engine, but typical for the 3.3L inline-six would be around 8.2:1, while V8 engines might range from 8.5:1 to 9.5:1 depending on the specific variant and tune.
Standard:
The standard transmission for most VK Commodore models was a 4-speed manual gearbox. Column shift was common on base models, while floor-mounted shifters were available and standard on higher-performance variants.
Optional:
A 3-speed Turbo Hydramatic automatic transmission (THM) was a popular option, particularly with the V8 engines and for drivers seeking increased comfort and ease of operation.
Features:
The manual would detail procedures for both manual and automatic transmissions, including clutch replacement, gearbox fluid changes, and automatic transmission servicing. Gear ratios and lubrication specifications for both transmission types would be included.

Wheelbase:
2700 mm (106.3 inches)
Track Width:
Front: approximately 1460 mm (57.5 in); Rear: approximately 1440 mm (56.7 in). Specifics might vary by trim level.
Wheel Bolt Pattern:
Typically 5 x 105 mm (4.13 inches) or 5 x 110 mm (4.33 inches) bolt pattern for common wheel fitments.
Ratings:
Safety ratings from the era were not standardized as they are today. However, the VK Commodore was designed with Australian road conditions in mind and featured a robust body structure. It would have met the safety standards of its time, including lap-sash seatbelts in the front and often in the rear.
Active Features:
Key active safety features would have included effective hydraulic disc brakes (front) and drum brakes (rear), and power-assisted steering on most models for improved control. Anti-roll bars were fitted to enhance handling stability.
Passive Features:
Reinforced safety cage construction, energy-absorbing steering column, padded dashboard and interior surfaces, and seatbelts were the primary passive safety features. Later models might have offered optional features like central locking.
Brake System Type:
Front: Ventilated Disc Brakes. Rear: Drum Brakes. Power assistance was common on most models.
Infotainment:
Infotainment systems in the VK Commodore were basic by modern standards. They typically included an AM/FM radio, often with a cassette player. Higher-spec models might have had more advanced radio units with more speakers. Features like graphic equalizers were considered premium.
Driver Assistance:
Driver assistance features were minimal. Power steering was available on many models, and some luxury variants might have had features like central locking or cruise control. ABS (Anti-lock Braking System) was not a standard feature and was very rare, if available at all, during this period.
Connectivity:
Connectivity as we know it today (Bluetooth, USB, smartphone integration) was non-existent. The primary form of 'connectivity' was through the vehicle's internal wiring harness for its electrical systems.
Service Intervals:
Typical service intervals for the VK Commodore would have included oil and filter changes every 5,000-10,000 km (3,000-6,000 miles) or 6-12 months, with more comprehensive services (including spark plugs, air filter, fuel filter) at higher mileage intervals. Cooling system flushes, brake fluid changes, and transmission fluid changes would also be scheduled.
Fluid Specifications:
Engine Oil: SAE 20W-50 or 10W-30 (depending on climate and engine type, refer to manual for specific grades). Coolant: Ethylene glycol-based coolant, typically a 50/50 mix with distilled water. Brake Fluid: DOT 3. Power Steering Fluid: ATF Dexron II. Transmission Fluid (Automatic): ATF Dexron II. Gear Oil (Manual Transmission & Differential): SAE 80W-90 GL-5.
Known Issues:
Common issues for the VK Commodore can include rust in common areas (wheel arches, sills, window surrounds), aging electrical components leading to intermittent faults, carburetor wear and tuning issues, suspension wear (bushings, ball joints), and potential radiator leaks or heater core issues. The V8 engines, particularly if not well-maintained, can experience oil leaks and overheating. Clutch wear on manual transmissions is also a common point of maintenance.
