Does the Acura MDX Have a Timing Belt or Chain?
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-06-25 · confidence: high
2022-2025 (4th gen; Type S from 2022) Acura MDX — Base 3.5L J35 V6 (TIMING BELT); Type S 3.0L turbo V6 (J30, TIMING CHAIN); both 0W-20, 10-speed auto, SH-AWD.
Answer: Base 3.5L V6 = TIMING BELT (~105,000 mi / 7 yr, interference). Type S 3.0L turbo V6 = TIMING CHAIN.
| Belt or chain | Timing chain — no scheduled replacement |
|---|---|
| Engine | Base 3.5L J35 V6 (TIMING BELT); Type S 3.0L turbo V6 (J30, TIMING CHAIN); both 0W-20, 10-speed auto, SH-AWD |
| Interference engine? | Yes — a failure can damage the engine |
| Service milestone | base ~105k timing belt + water pump + plugs + coolant |
The Acura MDX uses a timing chain designed to last the engine's lifetime, so there's no scheduled replacement — one less recurring service to budget for than belt-driven rivals.
Acura MDX note: The two engines differ fundamentally: the base J35 V6 has a TIMING BELT needing ~105k-mi replacement (interference), while the Type S 3.0L turbo V6 uses a maintenance-free chain. Know which you have.
