Engine Oil Filter Change:
Every 7,500-10,000 miles (12,000-16,000 km) or 6-12 months, whichever comes first. (Consult manual for exact recommendation).
Air Filter Replacement:
Every 15,000-30,000 miles (24,000-48,000 km) or 1-2 years.
Spark Plug Replacement:
Every 30,000-60,000 miles (48,000-96,000 km), depending on spark plug type (copper vs. platinum/iridium). Platinum plugs typically last longer.
Coolant Replacement:
Every 30,000-60,000 miles (48,000-96,000 km) or 2-4 years.
Timing Belt Replacement:
Critical: 60,000-90,000 miles (96,000-144,000 km) or 5-7 years. Failure can cause catastrophic engine damage.
Engine Oil Type:
SAE 10W-30 or 10W-40, API SJ or higher. (Consult manual for exact specification and viscosity for climate).
Coolant Type:
Ethylene glycol based, long-life coolant (e.g., Dex-Cool equivalent or a suitable Asian-spec coolant). Typically a 50/50 mix with distilled water.
Brake Fluid Type:

Common Problems:
Examples: Oil leaks (valve cover gaskets, oil pan gaskets), cooling system leaks (radiator, hoses, water pump), occasional electrical gremlins, premature wear of suspension components, issues with automatic transmission shifting (if applicable), EGR valve clogging. Timing belt maintenance is crucial.
