Oil Change Interval:
Typically every 10,000-15,000 km or 12 months, whichever comes first (check manual for exact details).
Timing Belt Interval:
Crucial! Every 50,000-75,000 km or 4-5 years. Failure can cause catastrophic engine damage.
Coolant Type:
Ethylene glycol-based antifreeze, mixed with distilled water (50/50 ratio). Consult manual for specific type and color.
Brake Fluid:
DOT 3 or DOT 4 (check manual). Recommended to flush and replace every 2 years due to hygroscopic nature.
Power Steering Fluid:
ATF Dexron II or equivalent (check manual).
Engine Reliability:
Timing belt tensioner and water pump are critical maintenance items. Valve stem seals can degrade leading to oil consumption. Twin Spark ignition system requires correct spark plug selection and gap.
Corrosion:
Susceptible to rust in common areas like wheel arches, sills, and around windows.
Electrical Gremlins:
Older wiring looms and connectors can be prone to issues, requiring careful diagnosis.
Suspension Bushings:
Rubber bushings in suspension and drivetrain can wear out, affecting handling and ride comfort.
