|
Fuel System
|
Carburetor Types:
|
Stromberg 2V/4V, Rochester Quadrajet 4V, possibly some Zenith applications.
|
Fuel Type:
|
Unleaded Petrol (Octane rating as per OEM recommendation, typically 91-95 RON for standard engines).
|
Maintenance
|
Service Intervals
|
Oil Change Interval:
|
Typically every 5,000 - 7,500 km or 6 months (whichever comes first), depending on driving conditions. Refer to manual for specific intervals based on engine and oil type.
|

|
Timing Belt Chain:
|
Holden V8s and Isuzu Diesel utilize timing chains which are generally designed for the life of the engine. RB30 Inline-6 uses a timing chain.
|
Fluid Specifications
|
Engine Oil:
|
API SG or SF specification, SAE 20W-50 or 10W-30 depending on ambient temperature (e.g., 20W-50 for hotter climates).
|
Coolant:
|
Ethylene Glycol based coolant with corrosion inhibitors, typically 50/50 mix with distilled water.
|
Brake Fluid:
|
DOT 3 or DOT 4 brake fluid (glycol-based).
|
Known Issues
|
Rust:
|
Common rust points include wheel arches, sills, door bottoms, boot lid, and around windscreen/rear window seals.
|
Carburetor Issues:
|
Carburetor wear, vacuum leaks, sticking floats, and maladjustment can lead to poor running or fuel economy.
|
Electrical Gremlins:
|
Corroded wiring connections, failing voltage regulators, and worn ignition components are common with age.
|
Suspension Wear:
|
Worn ball joints, tie rod ends, control arm bushings, and shock absorbers can lead to poor handling and steering wander.
|
Engine Mounts:
|
Degraded engine and transmission mounts can cause excessive vibration and noise transfer into the cabin.
