This vehicle does not have a timing "belt" it has a timing "chain". There is no service interval at which the chain needs to be replaced as part of any normal service schedule. The chain was designed to last the life of the vehicle without the need for any service or maintenance. The timing chain is replaced on a "need-to" basis, which on these engines, is few and far between. If/When the chain does need to be replaced, you'll experience engine performance issues and noise in the area of the chain. With this many miles on the vehicle, probably best to leave it alone, as replacing the chain is a 9 hours job (as it wasn't intended to be replaced, no need to make it easy to access).
