Engine Options:
The Isuzu D-Max of this era typically featured robust diesel engines, most commonly the 4JH1-TC (3.0L Turbo Diesel) and potentially the 4JA1/4JB1 variants (2.5L/2.8L Diesel). Petrol engines were less common in many markets.
Fuel Type:
Diesel (primarily)
Typical Hp Range:
Approximately 100-130 hp for the 3.0L Turbo Diesel, with torque figures around 200-250 lb-ft, though specific outputs varied by market and tune.
Injection System:
Commonly direct injection with turbocharging and intercooling. Some models might utilize electronic fuel injection (EFI).
Engine Codes:
Key engine codes to look for in the manual would include 4JH1-TC, 4JB1, 4JA1.
Manual Transmission:
Likely a 5-speed manual transmission was standard on many D-Max models of this generation.
Automatic Transmission:
A 4-speed automatic transmission was often an optional feature on higher trim levels or specific configurations.
Drivetrain:
Available in 4x2 (RWD) and 4x4 (4WD) configurations.
Manual Transmission Fluid:
Manuals typically specify GL-4 or GL-5 gear oil, with viscosity grades such as 75W-90 or 80W-90. Specific part numbers and capacities will be detailed within the manual.
Automatic Transmission Fluid:
Automatic transmissions would require specific ATF fluids, often Dexron III or equivalent. Refer to the manual for exact specifications and capacity.
Body Styles:
Single Cab, Extended/Space Cab, Crew Cab.
Wheelbase:
Varied by cab configuration, typically ranging from approximately 2,900 mm to 3,050 mm.
Curb Weight:
Estimated curb weight could range from 1,600 kg to 1,900 kg depending on configuration and engine.
Gross Vehicle Weight Rating Gvwr:
GVWR typically around 2,700 kg to 3,000 kg, depending on model and market regulations.
Crash Test Results:
Specific crash test ratings from agencies like NHTSA or Euro NCAP for this particular generation may vary by market and testing year. The manual may reference relevant safety standards.
ABS:
Anti-lock Braking System (ABS) was often an optional or standard feature on higher trims.
Traction Control:
Traction control systems were less common on base models of this era but might be present on higher-spec vehicles.
Airbags:
Front airbags for driver and passenger were typically standard or optional depending on market and trim level.
Seatbelts:
All seating positions equipped with three-point seatbelts, with pre-tensioners potentially included on front seats.
Oil Change:
Typical interval for diesel engines is 5,000-10,000 km (3,000-6,000 miles) or 6-12 months, depending on driving conditions and oil type. The manual will provide precise recommendations.
Timing Belt Or Chain:
Diesel engines of this era often utilized timing chains which are generally maintenance-free, but belt-driven variants would have specific replacement intervals detailed in the manual.
Engine Oil:
Diesel engine oil specifications will typically be API CF or higher, with viscosity grades like 10W-30 or 15W-40. The manual will specify the exact Isuzu-approved oils and capacities.
Coolant:
Engine coolant should be a mix of ethylene glycol-based antifreeze and deionized water. The manual will specify the correct type and mixture ratio for optimal protection against freezing and corrosion.
Common Problems:
Potential common issues for this generation can include turbocharger wear, EGR valve issues, injector pump problems (especially on older high-mileage units), suspension wear (bushings, ball joints), and potential rust in certain climates. The manual's troubleshooting section is invaluable here.
Engine Bolt Torques:
The manual contains precise torque specifications for critical engine components such as cylinder head bolts, main bearing caps, and connecting rod bolts, crucial for proper engine assembly and longevity.
Heritage:
Isuzu has a long-standing reputation for building durable and reliable diesel engines and commercial vehicles, which carries over to their light-duty pickup trucks like the D-Max.
Generation Timeline:
The Isuzu D-Max was introduced in 2002 as a successor to the Isuzu Faster. The 2003-2008 models represent the first generation (UG), characterized by its robust chassis and widespread diesel engine offerings. Subsequent generations introduced more modern styling and technology.
Manufacturing:
Isuzu D-Max vehicles are produced in various Isuzu plants globally, with significant production occurring in Thailand and other Asian countries for international markets. They are also often sold under different brand names (e.g., Chevrolet Colorado in some regions).
