Lexus GX 460 – No Timing Belt (Dual-Row Chain Only)
The GX 460 1UR-FE V8 has no timing belt — it uses a maintenance-free dual-row timing chain designed to outlast the engine. There is zero timing belt service cost throughout GX ownership. Regular 5W-30 oil changes at 10,000 km are all that is needed to protect chain life.
GX 460: Timing Belt or Chain?
The GX 460 1GR-FE V6 uses a timing chain, not a belt. No belt service needed. Change 5W-30 full synthetic every 10,000 km — this is the only chain maintenance required.
