Engine Description 1:
2.0L (1997cc) Inline-4, DOHC, 16-valve. Known for its durability and performance, especially in turbocharged variants (e.g., 4G63T in Galant VR-4).
Engine Description 2:
2.5L (2498cc) V6, SOHC, 24-valve. Offers smoother power delivery and a more refined driving experience.
Engine Description 3:
2.0L (1998cc) Inline-4 Diesel, SOHC, 8-valve. Known for fuel efficiency.
Horsepower 4G63 Na:
Approx. 140-150 hp (Naturally Aspirated variants)
Horsepower 4G63T:
Approx. 200-240 hp (Turbocharged variants, e.g., VR-4)
Horsepower 6A13:
Approx. 160-170 hp
Horsepower 4D68:
Approx. 80-90 hp
Fuel Delivery 1:
Multi-point Fuel Injection (MPI)
Fuel Delivery 2:
Turbocharged Direct Fuel Injection (TD05 Turbocharger for 4G63T)
Fuel Type:
Unleaded gasoline (for 4G63, 6A13), Diesel fuel (for 4D68)
Oil Change Interval:
Typically every 5,000-7,500 miles (8,000-12,000 km) or 6-12 months, depending on driving conditions and oil type.
Air Filter Replacement:
Every 15,000-30,000 miles (24,000-48,000 km) or as needed based on inspection.
Spark Plug Replacement:
Varies by plug type; iridium plugs can last 60,000-100,000 miles (96,000-160,000 km).
Timing Belt Replacement 4G63:
Critical interval, typically every 60,000 miles (96,000 km) or 5 years. Failure can cause catastrophic engine damage.
Transmission Fluid Change:
Automatic: Every 30,000-50,000 miles (48,000-80,000 km). Manual: Inspect periodically, change if contaminated or at higher mileage intervals.
Engine Oil Spec:
API Service SG, SH, SJ, SL or ILSAC GF-2, GF-3. Viscosity typically 5W-30 or 10W-30, depending on climate. Consult manual for exact spec.
Coolant Spec:
Ethylene glycol-based antifreeze/coolant, typically with a 50/50 mix with deionized water. Mitsubishi Super Long Life Coolant (MS-9770) or equivalent.
Brake Fluid Spec:
DOT 3 or DOT 4, depending on model year and system requirements.
4G63 Oil Sludge:
Older turbocharged 4G63 engines are susceptible to oil sludge buildup if maintenance intervals are not strictly followed, especially with incorrect oil or driving habits. Regular oil changes are paramount.
Timing Belt Wear:
The timing belt is a critical wear item on the 4G63. Premature wear or failure can be catastrophic.
Automatic Transmission Slippage:
Some automatic transmissions can develop slippage or harsh shifting over time, often related to fluid degradation or valve body issues.
Cv Joint Wear:
Front CV joints can wear out, leading to clicking noises during turns.
