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.

When does the Chevrolet Tahoe timing belt need replacing?
The Chevrolet Tahoe 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.
