Hyundai Tucson Mk3 1.7 CRDi timing belt interval — critical
The 1.7 CRDi engine in the Hyundai Tucson Mk3 uses a timing belt (not chain) that requires replacement every 120,000 km or 10 years. Many owners are unaware the 1.7 CRDi uses a belt rather than a chain. A snapped timing belt on this interference engine causes catastrophic valve and piston damage requiring a full engine replacement. Always confirm service history for timing belt replacement when buying a used Tucson 1.7 CRDi.
