Hp Range:
Typically ranges from 80-140 hp for diesel engines and 120-130 hp for gasoline engines in this era, depending on specific engine and tuning.
Torque Range:
Torque figures vary widely by engine, but common diesel engines could produce between 200-300 Nm.
Diesel Injection Type:
Indirect Injection (IDI) for older models (e.g., 4JA1) and Direct Injection (DI) with Common Rail (CRDI) for later models (e.g., 4JJ1).
Diesel Fuel Specification:
API CI-4 or CJ-4 rated diesel fuel recommended for common rail systems.
Timing Belt Chain:
Most Isuzu diesel engines of this era utilize timing chains, which are generally considered maintenance-free unless issues arise.
Manual Transmission:
Multiple manual transmission options available, often 5-speed, with varying gear ratios depending on application and model year.
Automatic Transmission:
Optional automatic transmissions were available on many D-Max Colorado models, typically 4-speed or 5-speed units.
Transfer Case:
4WD models feature a selectable 2WD/4WD transfer case, often with low-range gearing.
Manual Transmission Fluid:
GL-4 or GL-5 rated gear oil, typically SAE 75W-90 or SAE 80W-90, depending on manufacturer recommendation.
Automatic Transmission Fluid:
Dexron-III or equivalent ATF fluid is commonly specified for models of this era.
Engine Oil Change:
Typically every 5,000 - 10,000 km (3,000 - 6,000 miles) or 6-12 months, depending on usage conditions and oil type.
Fuel Filter Replacement:
Recommended every 20,000 - 40,000 km (12,000 - 24,000 miles) for diesel models, crucial for common rail systems.
Air Filter Replacement:
Every 15,000 - 30,000 km (9,000 - 18,000 miles) or as needed based on driving environment.
Engine Oil Specification:
Diesel engines: API CH-4, CI-4, or CJ-4; SAE 15W-40 or 10W-30 depending on climate. Gasoline engines: API SN/SM; SAE 5W-30 or 10W-30.
Coolant Specification:
Isuzu specified Long Life Coolant (LLC) or an equivalent ethylene glycol-based coolant with a 50/50 mix with distilled water.
Diesel Engine Glow Plugs:
Glow plugs can wear out and require replacement, especially in colder climates. The manual would detail testing and replacement procedures.
Common Rail Injectors:
Early common rail systems could be sensitive to fuel quality. The manual would cover diagnostic procedures for injector issues.
Suspension Wear:
Leaf springs and bushings on the rear suspension can experience wear over time due to load carrying and road conditions. The manual would provide replacement and adjustment guidance.
