Holden Commodore GMH 202 (Red) Wagon (1978–1980)

The VB Commodore, produced between 1978 and 1980, represents a pivotal moment in Holden's history, shifting away from the larger Kingswood/Premier models to create a more efficient and modern car design. As Holden's inaugural 'world car,' it introduces a fresh aesthetic while promising better fuel economy, becoming an instant classic. However, as these vintage vehicles age, they demand dedicated maintenance and expertise from their passionate owners to thrive.

Parts for the Holden Commodore GMH 202 (Red) Wagon

Known issues

Extensive rust (sills, wheel arches, floor pans, plenum chamber), worn suspension (especially ball joints and control arm bushes), oil leaks from engine and gearbox, failing brakes (corroded brake lines, sticking calipers), and electrical issues (wiring corrosion, faulty switches). Overheating can also be a problem if the cooling system isn't properly maintained. Interior trim is prone to cracking and fading.

WOF tips

Rust is the biggest WOF concern. Check all structural areas carefully. Suspension and brake components must be in good working order. Ensure all lights are functioning correctly. Significant oil leaks will result in a WOF failure. Tyres must meet legal requirements. Check seatbelts and mounting points for damage.

About the Holden Commodore GMH 202 (Red) Wagon

Originally available with a variety of inline-six and V8 engines, the VB Commodore offers reliable performance, though age can challenge its dependability. Extensive rust is a primary concern, particularly around sills and floor pans, necessitating protective measures for these vulnerable areas. Most original suspension components may require replacement due to wear; particularly ball joints and control arm bushes, making regular inspections essential. In terms of service intervals, paying close attention to the cooling system around 150,000 km is vital for long-term performance. Parts such as the water pump, thermostat, and radiator hoses are critical components that merit regular inspection to prevent overheating, and you can explore related offerings in our Cooling category. Furthermore, given the known electrical issues tied to wiring corrosion and faulty switches, owners should be proactive in monitoring the vehicle’s electrical systems.
For braking, both front and rear brake services ensure optimal performance—look to our specialised service packs to keep those critical systems in top shape. Given the age of these models, parts access can be a challenge, but with our dedicated product categories, you can easily find quality replacement components, from engine parts to suspension components.
