Parts for the Holden H Series GMH 253 (Red) Sedan 138kW (1974-1976)

Known issues

Rust is a major concern, particularly in coastal areas of New Zealand. Check the sills, floor pans, and around the window seals carefully. Engine wear, especially in high-mileage examples, is another common issue. Look for signs of oil leaks, excessive smoke, and unusual noises. The braking system, being relatively basic, can suffer from corrosion and require regular attention. Finally, electrical problems are common due to age and deteriorating wiring.

WOF tips

WOF inspectors will pay close attention to rust, especially in structural areas. Brake performance is critical, so ensure the brakes are functioning correctly and the lines are in good condition. Steering components are another key area for inspection, as wear and tear can lead to play in the steering. Lights must be functioning correctly and seatbelts must be in good working order. Modifications, if any, must be certified to comply with NZTA regulations.
