The Mitsubishi ASX 1.3 turbo (H5H 490) uses a timing chain, not a belt . This is confirmed by parts suppliers and workshop literature. The chain does not have a routine replacement interval, but can stretch on higher-mileage examples - particularly if oil changes are neglected. Use the correct 5W-40 oil specification to extend chain life .

• No routine replacement interval
• Use 5W-40 oil specification
