Depth Of Information:
Extremely detailed, covering everything from basic maintenance to complete engine and transmission rebuilds, including advanced diagnostics and troubleshooting.
Timing Belt Replacement:
Recommended every 60,000 miles (96,000 km) or 5 years, whichever comes first, due to interference engine design.
Engine Oil Change:
Every 3,000-5,000 miles (4,800-8,000 km) or 3-6 months, depending on driving conditions.
Transmission Fluid Change:
Manual: Every 30,000-60,000 miles (48,000-96,000 km). Automatic: Every 25,000-50,000 miles (40,000-80,000 km).
Coolant Replacement:
Every 30,000 miles (48,000 km) or 2 years.
Engine Oil Capacity:
Approximately 5.2 quarts (4.9 liters) with filter (check manual for exact amount).
Engine Oil Type:
10W-30 or 10W-40, API SG/SH certified (consult manual for specific viscosity based on climate).
Coolant Type:
Ethylene Glycol based antifreeze, 50/50 mix with distilled water.
Timing Belt Failure:
Due to interference engine design, timing belt failure is catastrophic. Regular replacement is critical.
Ecs Failure:
Electronic Control Suspension (ECS) components (shocks, control modules) can fail over time, leading to a harsh ride or leaks. Often converted to conventional suspension.
Turbocharger Issues:
Early turbocharger failures can occur due to heat soak and lack of proper maintenance or abuse. Intercoolers and piping can also develop leaks.
Active Aerodynamics:
The active front spoiler and rear wing mechanisms can become inoperative due to worn motors or linkage issues.
Head Gasket Failure:
While not as prevalent as on some other V6 engines, head gasket failures can occur, especially on high-mileage or modified vehicles.
Mitsubishi Performance Legacy:
Mitsubishi has a history of performance vehicles, including rally cars (Lancer Evolution) and sports cars, positioning the 3000GT as a flagship GT offering.
First Generation 1990-1993:
The 1992 model is part of the first generation of the 3000GT/GTO, characterized by its advanced technology, including four-wheel steering (AWS - standard on Japanese GTO, optional on US 3000GT), active aerodynamics (active front spoiler, active rear wing), and electronically controlled suspension (ECS).
Production Plants:
