Does the Toyota 4Runner Have a Timing Belt or Chain?
2010-2024 (4.0L V6) / 2025+ (2.4L turbo) Toyota 4Runner (4.0L V6 (1GR-FE) old-school NA, or 2024+ 2.4L turbo/hybrid; 0W-20 (older 5W-30)).
Answer: Timing CHAIN (4.0 V6 1GR-FE and new turbo) — no scheduled replacement.
A timing chain is designed to last the engine's lifetime, so there's no scheduled replacement — one less recurring service to budget for than belt-driven rivals.

Does the Toyota 4Runner have a timing belt or a timing chain?
Timing CHAIN (4.0 V6 1GR-FE and new turbo) — no scheduled replacement.
When does the Toyota 4Runner timing belt need replacing?
The Toyota 4Runner uses a timing chain, which is designed to last the life of the engine — there is no scheduled replacement interval. Inspect if you hear rattling on cold start.
What happens if a timing belt breaks?
On an interference engine, a snapped timing belt lets the valves and pistons collide, which can destroy the engine. That's why belt replacement intervals are not optional.
