Engine Displacement:
Commonly 1.9L (G190) and 2.3L (G230/4ZD1) gasoline engines.
Engine Displacement:
Commonly 2.2L (C223 and C223T turbodiesel) diesel engines.
Horsepower Torque:
Varies by specific engine; e.g., G230 could produce around 95-105 hp. Torque figures crucial for towing and hauling.
Horsepower Torque:
C223 diesel typically around 60-70 hp, with higher torque output than gasoline counterparts. Turbodiesel offered increased power.
Fuel Delivery:
Carbureted for most gasoline engines throughout the covered period; fuel injection introduced on later models. Diesel engines utilize indirect injection (IDI) with rotary or inline injection pumps.
Engine Codes:
G190, G230, 4ZD1, C223, C223T
Ratio Gasoline:
Typically around 8.5:1 to 9.5:1 for gasoline engines.
Ratio Diesel:
Typically around 21:1 to 23:1 for diesel engines.
Wheelbase:
Varies by configuration (e.g., standard bed, long bed), typically around 107 inches for standard cab long bed.
Overall Length:
Varies by configuration, e.g., around 178-188 inches for standard cab long bed.
Curb Weight:
Approximately 2,500 - 3,500 lbs, depending on engine, transmission, and configuration.
Payload Capacity:
Typically rated around 1,000 - 1,500 lbs.
Towing Capacity:
Varies significantly based on configuration, engine, and trailer brakes; often in the 2,000 - 5,000 lb range.
Common Fitments:
e.g., 205/75R15, 215/75R15, 225/75R15 depending on trim and options.
Pattern:
Commonly 5x114.3mm (5x4.5 inches).
Oil Change:
Typically every 3,000 to 5,000 miles or 3 to 6 months, depending on driving conditions and oil type.
Transmission Fluid Change:
Manual: Inspect every 15,000-30,000 miles, change as needed or every 60,000 miles. Automatic: Every 30,000-50,000 miles.
Coolant Change:
Every 2 years or 30,000 miles.
Engine Oil:
API SF or SG service classification. Viscosity typically 10W-30 or 10W-40 for gasoline engines, 15W-40 for diesel engines. Check owner's manual for exact recommendations.
Coolant:
Ethylene glycol-based coolant, typically a 50/50 mix with distilled water. Consult manual for specific type (e.g., traditional green coolant).
Common Problems:
Rust/corrosion (especially in salt-belt regions), carburetor issues (gumming, leaks), starter motor problems, aging rubber hoses and belts, suspension wear (ball joints, bushings), exhaust system leaks, glow plug issues on diesel models, clutch wear.
