Body Styles Covered:
Likely covers both short-wheelbase (SWB) and long-wheelbase (LWB) variants, common for this era of Trooper/Jackaroo.
Curb Weight Range:
Approximately 4,300 - 4,800 lbs (varies by configuration)
Gross Vehicle Weight Rating:
Typically in the range of 5,700 - 6,200 lbs (varies by configuration and market).
Standard Safety Features:
Seat belts (likely three-point in front, two-point in rear for earlier models), reinforced body structure.
Available Safety Features:
Anti-lock Braking System (ABS) likely available on higher trims or later models.
Oil Change Interval:
Typically every 3,000-5,000 miles or 3-6 months (refer to manual for exact recommendation based on driving conditions).
Transmission Fluid Change Interval:
Every 30,000-60,000 miles for automatic, manual fluid varies (consult manual).
Engine Oil Viscosity:
Likely 5W-30 or 10W-30 API SG/SH or later (verify in manual for specific climate and model).
Coolant Type:
Ethylene glycol-based coolant, typically a green or orange type (verify in manual for correct specification and mixture ratio).
Automatic Transmission Fluid:
Dexron-II or Dexron-III (verify in manual for specific transmission variant).
Brake Fluid:
DOT 3 or DOT 4 (verify in manual).
Power Steering Fluid:
Typically ATF Dexron-II/III or specific power steering fluid (verify in manual).
Transfer Case Fluid:
Likely GL-4 or GL-5 gear oil (verify in manual).

GL-5 gear oil (verify in manual for front and rear differentials).
Common Wear Items:
Ignition components (spark plugs, wires), fuel injectors, exhaust system components, suspension bushings, radiator, and water pump.
V6 Engine Considerations:
The 6VD1 V6 engine is generally robust but can be susceptible to oil leaks from valve covers and intake manifold gaskets over time. Timing belt (if applicable, though this era often used chains for V6) maintenance is critical.
Isuzu SUV Legacy:
Isuzu has a long history in off-road vehicles and SUVs, with the Trooper being a foundational model in their global lineup.
