Oil Change Km:
Every 5,000 - 7,500 km or 6 months (whichever comes first), especially under spirited driving conditions.
Air Filter Replacement Km:
Every 15,000 - 20,000 km or annually.
Spark Plug Replacement Km:
Every 30,000 - 40,000 km (depending on plug type, e.g., platinum or iridium).
Timing Belt Replacement Km:
Every 90,000 - 100,000 km or 5-7 years, crucial for the 4G63T engine.
Engine Oil Type:
API SG/SH or higher, SAE 10W-30 or 10W-40 is commonly recommended for turbocharged engines.
Engine Oil Capacity Liters:
Approx. 4.5 Liters (with filter change)
Coolant Type:
Ethylene glycol-based antifreeze with corrosion inhibitors (e.g., Mitsubishi DiaQueen Super Long Life Coolant).
Transmission Fluid Type:
API GL-4 or GL-5, SAE 75W-90 (for manual transmission).
Transfer Case Fluid Type:
API GL-4 or GL-5, SAE 75W-90.
Rear Differential Fluid Type:
API GL-5, SAE 75W-90 (for standard differential). Check AYC system for specific fluid requirements.
Ayc Fluid Type:
Specific hydraulic fluid (check manual for part number and type).
Brake Fluid Type:
DOT 3 or DOT 4.
Engine Wear:
Oil consumption can increase with mileage. Timing belt tensioner failure can lead to catastrophic engine damage if not replaced at intervals. Cracked exhaust manifolds can occur.
Ayc System:
AYC pump and hydraulic lines can develop leaks or fail over time, affecting handling. Sensor issues can also occur.
Rust:
As with many cars of this era, rust can be a concern, particularly around wheel arches, sills, and rear quarter panels, especially in regions with road salt.
Turbocharger:
Turbo seals can degrade, leading to oil leaks into the intake or exhaust. Regular oil changes with quality oil are critical for longevity.
