Cooling System Type: Pressurized liquid cooling system with thermostatically controlled fan. Lubrication System Oil Type Recommendation: API CI-4 or higher for diesel engines (e.g., Isuzu DPD or SAE 15W-40 API CI-4 diesel engine oil, specific grade based on ambient temperature). Emission Controls Systems: May include EGR (Exhaust Gas Recirculation), DPF (Diesel Particulate Filter) for later models, and catalytic converters depending on emission standards for Europe and Australia. 🔧 Transmission Standard Type: Likely a 5-speed or 6-speed manual transmission as standard on most models. Optional Type: Some variants may have offered an optional automatic transmission. Features Clutch: Hydraulically actuated single dry plate clutch. Fluid Specifications Manual Transmission Fluid: API GL-4 or GL-5, SAE 75W-90 or 80W-90 gear oil (specific recommendation in manual). Automatic Transmission Fluid: Dexron III/Mercon or equivalent (if equipped). 📐 Dimensions Exterior Wheelbase Range: Highly variable depending on specific NPR, NQR, NPS model (e.g., from approx. 2.5m to over 4m). Overall Length Range: Varies significantly based on chassis configuration and body type (e.g., single cab, crew cab, chassis cab). Weights Gvwr Range: Gross Vehicle Weight Rating varies by model, from light-duty (e.g., 3.5t) to medium-duty (e.g., 7.5t or higher for NQR/NPS). Curb Weight Range: Dependent on configuration, typically 2,000 kg to 3,500 kg. Front Axle Weight Rating: Specified per model variant, crucial for load distribution. Rear Axle Weight Rating: Specified per model variant, crucial for load distribution. 🛡️ Safety Features Ratings Crash Test Data: Not typically rated by consumer organizations like Euro NCAP or NHTSA for commercial vehicle variants. Focus is on built-in safety features. Active Features Braking System: Hydraulic disc brakes front and rear, with ABS standard on most export models of this era. Parking brake typically mechanical, acting on rear wheels. Steering: Power steering is standard on most variants for improved maneuverability and control. Passive Features Occupant Protection: Reinforced cab structure, three-point seatbelts, driver airbag (may be optional on some base...
