Engine Code Gasoline:
Likely 6G72 (3.0L V6 SOHC/DOHC MPI) or 6G74 (3.5L V6 SOHC/DOHC MPI), possibly 6G75 (3.8L V6 SOHC MIVEC) for later models.
Engine Displacement Common:
3.0L (2972 cc) and 3.5L (3497 cc) gasoline V6 are most prevalent for these years.
Horsepower 3.0L:
Approximately 175-215 hp (depending on SOHC/DOHC and market tuning).
Torque 3.0L:
Approximately 180-225 lb-ft (depending on SOHC/DOHC and market tuning).
Horsepower 3.5L:
Approximately 200-235 hp (depending on SOHC/DOHC and market tuning).
Torque 3.5L:
Approximately 220-245 lb-ft (depending on SOHC/DOHC and market tuning).
Horsepower 3.8L:
Approximately 250-265 hp (if 6G75 is present).
Torque 3.8L:
Approximately 250-260 lb-ft (if 6G75 is present).
Fuel Delivery:
Electronic Multi-Point Fuel Injection (MPI) or Gasoline Direct Injection (GDI) on later/higher spec models.
Recommended Fuel:
Unleaded gasoline (Octane rating varies by market and specific engine tuning, typically 87-91 AKI).
Fuel Tank Capacity:
Typically around 88-92 Liters (23-24 US Gallons).
Oil Change Interval:
Typically every 5,000-7,500 miles (8,000-12,000 km) or 6 months, whichever comes first, using the correct oil viscosity.
Air Filter Replacement:
Every 15,000-30,000 miles (24,000-48,000 km) or as needed based on driving conditions (dusty environments require more frequent checks).
Spark Plug Replacement:
Platinum-tipped plugs typically last 60,000-100,000 miles (96,000-160,000 km). Iridium plugs may last longer. Consult manual for exact type and interval.
Timing Belt Replacement:
If equipped with a timing belt (less common on V6s of this era which often use chains), typically around 60,000-90,000 miles (96,000-145,000 km). Check if engine uses belt or chain.
Coolant Flush Replacement:
Every 30,000-50,000 miles (48,000-80,000 km) or 2-4 years.
Engine Oil Viscosity Gasoline:
Likely 5W-30 or 5W-40 synthetic or semi-synthetic oil (verify with owner's manual or specific engine spec).
Engine Oil Capacity:
Around 4.5-5.5 Liters (4.8-5.8 US Quarts) for V6 engines, including filter (verify).
Brake Fluid Type:
DOT 3 or DOT 4 (check reservoir cap or manual).
Power Steering Fluid:
Likely ATF Dexron II/III or specific Mitsubishi power steering fluid (verify).
Transfer Case Fluid:
DIAMOND ATF SP-III or equivalent (verify).
Differential Fluid Front Rear:
API GL-5 gear oil, SAE 75W-90 or 80W-90 (verify specific viscosity and LSD additive requirements if applicable).
Common Wear Items:
Suspension bushings, ball joints, tie rod ends due to age and load. Radiator and cooling system components (hoses, thermostat) can also degrade.
Engine Reliability:
Generally robust V6 engines, but like all high-mileage engines, can experience issues like oil leaks, carbon buildup, and sensor failures. Timing chain issues are rare if maintenance is kept up.
Transmission Issues:
Automatic transmission shifting issues or solenoid failures can occur. Regular fluid changes are critical. Manual transmissions are typically robust.
Electrical Gremlins:
Corrosion in wiring harnesses, failing window regulators, and sensor issues are not uncommon in older vehicles, especially those used in harsh environments.
Rust Concerns:
Body-on-frame SUVs can be susceptible to frame rust, especially in areas with road salt. Check frame rails, body mounts, and suspension components.
