How often should the timing belt be replaced?

Typically every 60,000-100,000 km or 5-7 years, whichever comes first. A broken timing belt can cause valve damage and extremely expensive engine repairs.

Does the timing chain need to be replaced?

Timing chains are理论上 maintenance-free for life, but in practice may stretch due to insufficient lubrication. Inspect and replace if you hear abnormal noise or see fault codes.
