🔧 Maintenance

Engine Oil And Filter:

Every 5,000-7,500 miles (8,000-12,000 km) or 6-12 months, whichever comes first (refer to manual for exact specification).

Timing Belt Replacement:

Critical for 4G64 and 6A13TT engines. Typically every 60,000-90,000 miles (100,000-150,000 km). Failure leads to catastrophic engine damage.

Spark Plugs:

Refer to manual; typically 60,000-100,000 miles depending on type (Iridium recommended).

Engine Oil:

Refer to manual for viscosity grade (e.g., 5W-30, 10W-30) and API/ILSAC specifications.

Coolant:

Mitsubishi Super Long Life Coolant (or equivalent ethylene glycol-based coolant with appropriate additives).

Automatic Transmission Fluid:

Mitsubishi ATF SP-III or equivalent.

Brake Fluid:

DOT 3 or DOT 4 brake fluid.

Power Steering Fluid:

Refer to manual; typically a Dexron III equivalent ATF or specific power steering fluid.

Common Issues 4G64:

Oil leaks from valve cover gasket and oil pan, potential for sludge buildup if maintenance is neglected, timing belt failure if not replaced on schedule.

Common Issues 6A13Tt:

Turbocharger wear, intercooler leaks, ignition coil issues, spark plug fouling, potential for sludge in oil passages, exhaust manifold cracks, sensitive to fuel quality.
