Lexus IS 250/300h/350 – No Timing Belt (Timing Chain Only)
The IS does not have a timing belt — all IS variants (IS 250 2GR-FSE, IS 300h 2AR-FXE, IS 350 2GR-FSE) use a timing chain. There is no scheduled timing belt replacement The chain requires no servicing beyond regular oil changes with the correct grade and viscosity. This eliminates the timing belt service common on other brands.
IS: Timing Belt or Chain?
The Lexus IS does not have a timing belt. All IS engines — 2GR-FSE, 2GR-FE, and 2AR-FXE — use timing chains. There is no scheduled timing belt replacement on the IS. If a workshop quotes you for a timing belt service, they are either mistaken about the vehicle or referring to a different part. Maintain the timing chain by using 0W-20 full synthetic oil and changing it every 10,000 km.
