🔧 Maintenance

Oil Change Interval:

Every 3,750 - 5,000 miles (6,000 - 8,000 km) or 6 months, whichever comes first (check manual for precise recommendation).

Air Filter Replacement:

Every 15,000 - 30,000 miles (24,000 - 48,000 km) or as needed based on driving conditions.

Every 30,000 - 60,000 miles (48,000 - 96,000 km) depending on spark plug type (copper, platinum, iridium).

Timing Belt Replacement:

CRITICAL: For the 1.8L BP engine, typically every 60,000 miles (96,000 km) or 4 years. Failure to replace can cause catastrophic engine damage due to interference design. The 1.6L B6 SOHC may have a non-interference design but still requires regular replacement.

Engine Oil Viscosity:

API SG, SAE 5W-30 or 10W-30 is commonly recommended (refer to manual for specific temperature ranges and approved classifications).

GL-4 gear oil, SAE 75W-90 is a common recommendation.

Transmission Fluid Automatic:

Dexron III (or equivalent) automatic transmission fluid.

Brake Fluid Type:

DOT 3 or DOT 4 brake fluid.

Engine Oil Leaks:

Valve cover gasket and oil pan gasket can degrade over time, leading to leaks.

Suspension Wear:

Worn ball joints, tie rod ends, and strut mounts are common with age and mileage.

Exhaust System:

Rust and corrosion can affect exhaust components, particularly in regions with harsh winters.

Cv Axle Boots:

Torn CV axle boots are a common failure point, leading to premature wear of the CV joints.

Radiator Corrosion:

Aluminum radiators can develop leaks or corrode over time.

Fuel Injector Clogging:

Can occur with age and deposits, affecting performance and fuel economy.
