This manual typically covers naturally aspirated variants. Turbocharged versions (like the 4G64T) would have specific service procedures not detailed here.
Fuel Delivery:
Multi-point Fuel Injection (MPI)
Ignition Type:
Electronic Ignition
Fuel Type:
Unleaded Gasoline
Design:
SOHC (Single Overhead Camshaft) or DOHC (Double Overhead Camshaft) depending on specific 4G64 variant, featuring 16 valves (4 valves per cylinder)
Timing Mechanism:
Timing Belt Driven (typically)
Oil Capacity:
Approximately 4.5 Liters (check manual for exact specification)
ECU Type:
Engine Control Unit (ECU) managed
Emissions Compliance:
Designed to meet emissions standards of its respective production era.
Diagnostic Interface:
OBD-II (On-Board Diagnostics II) compliant for vehicles from the mid-1990s onwards.
Oil Change Interval:
Typically 5,000 - 7,500 miles (8,000 - 12,000 km) or 6-12 months, subject to driving conditions and manufacturer recommendations. Consult manual for specific intervals.
Engine Oil Type:
API SN or higher, SAE 5W-30 or 10W-30 viscosity grade recommended (refer to manual for exact specification).
Coolant Type:
Ethylene Glycol-based antifreeze with demineralized water (typically a 50/50 mix). Specific color and type as per manufacturer recommendation.
Transmission Fluid Type:
Refer to vehicle-specific manual for Automatic Transmission Fluid (ATF) or Manual Transmission Fluid (MTF) specifications (e.g., ATF SP-III for Hyundai, DiaQueen SK for Mitsubishi).
Brake Fluid Type:
DOT 3 or DOT 4 (refer to vehicle-specific manual).
Power Steering Fluid Type:
Specific power steering fluid (refer to vehicle-specific manual, often Dexron III compatible).
Common Problems:
Oil leaks from valve cover or oil pan gaskets, potential timing belt wear (critical component for interference engine design), occasional coolant leaks, carbon buildup on intake valves (especially on direct injection variants, though this manual likely covers port injection).
Cooling System Issues:
Thermostat failures, radiator leaks, water pump leaks, and heater core issues can occur with age and mileage.
Engine Mounts:
Engine mounts can degrade over time, leading to increased vibration and engine movement.
Sensor Failures:
Failure of sensors like the Oxygen sensor (O2 sensor) or Mass Airflow (MAF) sensor can affect fuel economy and engine performance.
Oil Filter Example:
Example: Mitsubishi MD348615, Hyundai 26300-35503 (specific part number varies by vehicle application).
Spark Plug Type:
Typically platinum or iridium tipped plugs (e.g., NGK BKR5EKUP or similar). Refer to manual for exact gap and part number.
Timing Belt Replacement Interval:
Recommended replacement interval is critical, often between 60,000 to 100,000 miles (96,000 to 160,000 km). Failure to replace can cause catastrophic engine damage.
Preventative Maintenance:
Regularly check and top up fluids, inspect belts and hoses, listen for unusual noises, and address check engine lights promptly.
Manufacturer Origin:
Mitsubishi Motors
Engine Legacy:
The 4G6 engine family is a well-established and widely used series of engines by Mitsubishi, also adopted by Hyundai and other manufacturers. It has seen various iterations and improvements over its production life.
