HVAC:
Heating, ventilation, and air conditioning (HVAC) system, compressor, condenser, evaporator, refrigerant, heater core.
Body And Frame:
Body panel removal and installation, chassis, doors, hood, trunk, glass, seals, interior trim.
Chassis Electrical:
Instrument cluster, dashboard lights, warning indicators, body control modules.
Preventative Maintenance:
Oil changes, filter replacements, spark plug replacement, fluid level checks, belt inspections, brake pad wear checks.
Diagnostics And Troubleshooting:
Systematic fault finding, error code interpretation (OBD-I), component testing, wiring diagrams.
Repair And Rebuild:
Component disassembly, repair, and reassembly procedures for all major systems.
Torque Specifications:
Detailed torque values for critical fasteners throughout the vehicle.
Wiring Diagrams:
Comprehensive electrical schematics for all vehicle systems.
Special Tools:
Identification and usage of specific Mitsubishi special tools required for certain procedures.
Depth:
Comprehensive, covering everything from basic fluid changes to full engine and transmission rebuilds, including advanced diagnostics.
Oil Change:
Every 3,000-5,000 miles (5,000-8,000 km) or 6 months, depending on driving conditions and oil type.
Timing Belt:
Recommended replacement every 60,000 miles (96,000 km) or 4 years for 4G63 engines. V6 (6G71) also requires replacement.
Spark Plugs:
Typically every 30,000 miles (48,000 km) for standard plugs.
Engine Oil:
API SG/SH or higher. Viscosity varies by climate, e.g., 10W-30 or 10W-40.
Coolant:
Ethylene glycol-based antifreeze (50/50 mix with distilled water).
Transmission Fluid Atf:
Mitsubishi DiaQueen ATF SP-II or equivalent (Dexron II/III for some markets/models).
Brake Fluid:
DOT 3 or DOT 4.
Engine Reliability:
4G63 engine is generally robust; head gasket failures can occur with age/overheating. Timing belt maintenance is critical.
Transmission Issues:
Automatic transmission can develop internal wear; regular fluid changes help. Manual transmissions are generally durable.
Suspension Wear:
Bushings and ball joints can wear out, leading to clunking noises and alignment issues.
Electrical Problems:
Corrosion in wiring harnesses, aging sensors, and faulty window regulators are common with age.
Body Rust:
Prone to rust in fender wells, rocker panels, and around the rear wheel arches in areas with road salt.
