Does the Jeep Gladiator Have a Timing Belt or Chain?
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.
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 Jeep Gladiator have a timing belt or a timing chain?
Timing CHAIN — no scheduled replacement.
When does the Jeep Gladiator timing belt need replacing?
The Jeep Gladiator 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.
