Does the Jeep Grand Cherokee Have a Timing Belt or Chain?
2022-2024 (WL) Jeep Grand Cherokee (3.6L Pentastar V6, 2.0L turbo, or 4xe PHEV (5.7 HEMI in earlier WK2); 0W-20 synthetic; 8-speed auto).
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.

The Jeep Grand Cherokee 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.
