⚙️ Engine Specifications

Engine Type:

Likely to include Isuzu's robust diesel engines (e.g., 4JB1, 4JA1 series) and potentially gasoline options (e.g., G200Z, C190). Specific engine codes covered would be detailed within the manual.

Typical Horsepower Range:

Diesel engines typically ranged from 70-100 HP, while gasoline engines could be in the 80-100 HP range, depending on specific displacement and tuning.

Typical Torque Range:

Diesel engines would offer significantly higher torque, crucial for hauling and off-road capability, often exceeding 150 lb-ft.

Fuel Delivery:

Includes information on indirect injection diesel pumps (e.g., Bosch VE or similar) and carburetor/EFI gasoline systems.

Timing Belt Or Chain:

Many Isuzu diesel engines of this era utilize timing belts, with specified replacement intervals crucial for preventing catastrophic engine damage. Gasoline engines might use belts or chains.

🔧 Transmission

Manual Transmission:

Likely includes 5-speed manual transmissions (e.g., MYY5T or similar), with detailed repair and adjustment procedures.

Automatic Transmission:

Optional automatic transmissions might be available, with specific models and service procedures covered.

Clutch Service:

Comprehensive guidance on clutch replacement, including specifications for pressure plate, clutch disc, and release bearing.

📐 Dimensions

Body Styles:

Offered primarily as a pickup truck (single cab, extra cab) and potentially chassis cab variants.

Curb Weight:

Varies significantly by configuration (cab type, engine, drivetrain), but typically in the range of 3,000-4,000 lbs (1360-1815 kg).

Payload Capacity:

Designed for utility, with payload capacities often exceeding 1,500 lbs (680 kg).

🛡️ Safety Features

Safety Standards:

While specific NHTSA/IIHS ratings for this era and model might be limited, the manual will detail the vehicle's built-in safety features and passive restraints.

Active Safety:

Information on braking systems, steering, and suspension that contribute to active safety.

Passive Safety:

Details on seat belt systems, body structure, and potential airbag systems (though airbags were less common in base models of this era).

💡 Technology Features

Infotainment System:

Base level for the era, typically including an AM/FM radio with cassette player. Speaker configuration and potential upgrades are not a focus of this repair manual, but electrical system coverage would apply.

Driver Assistance Features:

Limited to non-existent by modern standards. Features would be basic, focused on mechanical reliability and driver control.
