Lexus NX 200t/300/300h – No Timing Belt (Timing Chain Only)
All NX variants use a timing chain, not a timing belt. The 8AR-FTS (NX 200t/300) and 2AR-FXE (NX 300h) both have oil-lubricated chains designed for the engine's service life. No timing belt replacement cost ever. For the turbo NX 200t/300, strict 7,500 km oil change intervals with 5W-30 full synthetic are the most important maintenance step for chain longevity.
NX: Timing Belt or Chain?
The Lexus NX uses timing chains, not a belt — on both the 8AR-FTS turbo and 2AR-FXE hybrid. No timing belt service exists for the NX. The turbocharged 8AR-FTS chain depends heavily on oil quality — 0W-20 full synthetic every 10,000 km is the key maintenance action.
