The Holden HZ, produced from 1976 to 1977, marks a significant milestone in the legendary 'Kingswood' lineage. It embodies reliable family motoring that Kiwis have come to trust. With enhancements like the Radial Tuned Suspension (RTS), the HZ provides improved handling and comfort, making it a preferred option for diverse lifestyles ranging from family outings to hardworking commercial duties. Whether you choose a sedan, wagon, ute, or panel van, the HZ remains a versatile companion on the roads of New Zealand. Let's explore what makes the HZ so memorable and why it continues to hold a special place in our automotive history.
Given their age, rust is a major concern with the HZ, particularly in areas like the sills, wheel arches, and around the windscreen. The 'Red Motor' inline-six engines are generally reliable but can suffer from oil leaks and worn valve guides. The V8s are known for their power but can be prone to overheating if the cooling system isn't maintained. The Trimatic automatic transmissions are robust but can become sluggish with age. Suspension components, like ball joints and bushes, are also likely to need replacement.
When taking an HZ for a WOF, pay close attention to rust, especially in structural areas. Check all lights are working and lenses aren't damaged. Suspension components should be inspected for wear and play. Brake lines and hoses should be free from leaks and in good condition. Tyre condition and tread depth are also critical. Ensure the steering has no excessive play. Exhaust systems on older vehicles are often prone to corrosion and leaks which will cause a WOF failure.
The Holden HZ series wasn't just another vehicle; it was about continuous refinement and a commitment to enhanced driving dynamics. Though changes in design from the HX were subtle, the advancements under the surface were remarkable. Its Radial Tuned Suspension revolutionized how the HZ handled, ensuring a more planted and stable ride. The engine range includes the efficient 2.8L 'Red Motor' inline-six, known for its reliability, and the powerful 5.0L Holden V8, favoured for its performance.
However, like any classic, the HZ does come with its share of maintenance needs. Owners should keep an eye on the cooling system, particularly around the 150,000km mark, when parts like the water pump, thermostat, and radiator often require inspection or replacement. This leads us naturally to our selection of products in the Cooling category. Additionally, the braking system—especially pads and rotors—demands attention every 20,000-30,000 km for optimal safety. Check out our Braking category for all your service pack needs. As with all classic cars, regular maintenance of parts like wiper blades and filters is vital. You can’t go wrong with our Filtration products to keep everything running smoothly. The HZ isn't just a car; it's a legacy worth preserving, with owners continuing to maintain its charm and reliability well into the present day.
