2020-2024 (JT) Jeep Gladiator — 3.6L Pentastar V6 or 3.0L EcoDiesel; 0W-20 (gas) / 5W-40 (diesel); 8-speed auto / 6-speed manual.
Answer: Timing CHAIN — no scheduled replacement.
| Belt or chain | Timing chain — no scheduled replacement |
|---|---|
| Engine | 3.6L Pentastar V6 or 3.0L EcoDiesel; 0W-20 (gas) / 5W-40 (diesel); 8-speed auto / 6-speed manual |
| Interference engine? | Not flagged in our data — confirm in your manual |
The Jeep Gladiator 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.
Jeep Gladiator note: Like the Wrangler it's based on, the defining maintenance is gear oils — front/rear differential and transfer-case fluid every ~30k (or after any water crossing), not the chain-driven engine.
