Power And Torque 3.0L 4Jj1-Tc:

Approx. 130-146 hp (97-109 kW) and 294-320 Nm torque (specific figures vary by tune and market).

Fuel Injection System:

Common Rail Direct Injection (CRDI) for diesel engines.

Specific Diesel Engine Codes:

4JJ1-TC (3.0L Turbo Diesel Common Rail), 4JK1-TC (2.5L Turbo Diesel Common Rail)

🔧 Transmission

Manual Transmission:

Typically a 5-speed manual transmission (e.g., MUX-series).

Automatic Transmission:

Often a 4-speed automatic transmission (e.g., GM 4L30-E or similar variants).

Drivetrain Options:

Available in 2WD (RWD) and 4WD configurations, often with a selectable 4WD system with transfer case.

📐 Dimensions

Wheelbase Options:

Varies by cab configuration (Single, Space, Dual), typically ranging from around 2950 mm to 3380 mm.

Ground Clearance:

Typically around 200-225 mm, depending on suspension and tire fitment.

Bed Length Options:

Varies significantly by cab configuration, from short beds on single cabs to longer beds on extended or dual cabs.

Gross Vehicle Weight Rating:

Typically in the 2800-3000 kg range (GVWR).

🛡️ Safety Features

Crash Test Information:

ANCAP ratings for the RG Colorado generation can be found (typically 3-4 stars for models from this era). Isuzu D-Max would have similar safety structures and ratings relevant to their target markets.

Braking Systems:

Front ventilated discs, rear drum brakes are common. ABS (Anti-lock Braking System) and EBD (Electronic Brake-force Distribution) were available on higher trims or as options.

Occupant Protection:

Front airbags for driver and passenger. Seatbelt pre-tensioners and load limiters.

💡 Technology Features

Audio System:

Base models typically featured an AM/FM radio with CD player. Higher trims might have offered auxiliary input or more speakers.

Traction Control System (TCS) and Electronic Stability Control (ESC) were becoming more common in this era, but might have been optional or only on higher trims.

Auxiliary Inputs:

Auxiliary audio input jacks were starting to appear on some sound systems.

🔧 Maintenance

Oil Change Interval Diesel:

Typically every 5,000 km or 6 months for severe use, or 10,000 km / 12 months for normal use, depending on operating conditions and oil specification. Refer to manual for precise intervals.
