Parts for the Holden H Series GMH 173 (Red) Sedan 75kW (1977-1980)

Known issues

Rust is the biggest enemy of any H Series, especially in areas like the sills, wheel arches, and around the windows. Check the condition of the brake lines, fuel lines, and suspension components. Engine wear and oil leaks are common in older engines, so listen for any unusual noises and check for blue smoke from the exhaust, especially on cold starts. Carburetor issues are common, but are usually easy to fix. Also be aware of the availability and cost of some parts as these classics are now ageing with parts getting harder to source.

WOF tips

WOF inspections will focus on structural rust (especially around suspension mounting points and seat anchorages), brake performance, steering play, and the condition of lights and tires. Be aware that any significant rust will likely result in a failed WOF. Check the condition of seatbelts and ensure they function correctly. Windscreen wipers and washers must be in good working order. Exhaust system leaks are another common failure point.

About the Holden H Series GMH 173 (Red) Sedan 75kW (1977-1980)

The Holden H Series encompasses a range of models from sedans to wagons and utes, each exemplifying practical design with vintage Aussie flair. When it comes to maintaining these classics, regular service intervals should not be overlooked. For the longevity of your H Series, paying attention to specific parts that commonly require replacement is crucial. Engine oil, carburetor settings, and fuel lines should be inspected periodically to keep the car running smoothly. Additionally, the cooling system demands attention, particularly around the 150,000 km mark. Essential parts such as the water pump, thermostat, and radiator hoses should be checked to prevent overheating. [This naturally links to /shop/cooling]

Braking components are another area that needs focus; both front and rear brakes may require servicing. Consider engaging in a Front Brake Service or a Rear Brake Service to ensure your classic has solid stopping power, especially when navigating NZ roads.

And as rust proves to be the biggest enemy of the H Series, particularly in coastal environments, be vigilant about inspecting the vehicle's body for corrosion. Checking sills, wheel arches, and around windows is essential, along with being aware of parts availability as some may become harder to source over time. Maintaining the integrity of your vehicle not only preserves its value but also ensures a safer driving experience.
