Lexus UX 200/250h Timing Chain – No Belt Required
Both UX variants use oil-lubricated timing chains. No timing belt replacement ever. Regular 0W-20 (UX 200) or 0W-16 (UX 250h) oil changes are the only timing chain maintenance needed.
UX Timing Chain
The UX M20A-FKS and M20A-FXS engines both use timing chains. These compact 2.0L engines are well-designed and the chains are trouble-free with proper 0W-16/0W-20 full synthetic oil at 10,000 km intervals. No belt replacement needed on the UX — the chain is a lifetime component under normal maintenance.
