Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-06-25 · confidence: high
2018-2024 (3.6L V6 era; 2025+ switched to 2.5L turbo) Buick Enclave — 3.6L V6 (LFY), 0W-20 dexos1 Gen 3, 9-speed auto.
Answer: Timing CHAIN — no scheduled replacement.
| Belt or chain | Timing chain — no scheduled replacement |
|---|---|
| Engine | 3.6L V6 (LFY), 0W-20 dexos1 Gen 3, 9-speed auto |
| Interference engine? | Not flagged in our data — confirm in your manual |
The Buick Enclave 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.
Buick Enclave note: GM's high-feature 3.6 V6 has a history of timing-chain stretch on earlier versions — on-time (or early) oil changes are the single best prevention. The 2025+ Enclave dropped the V6 for a 2.5L turbo, so this applies to 2018-2024.
