Timing belt

[Tontos]

Forgive me if this is the dumbest question ever posted. Got a 2004 Exec, looks like I only got the Fan belt to change though, is this right they don't have timing belts/chains anymore, something to do with the variable valve timing engines? Cant beliebe Holden would miss a trick on getting me to continually change my timing belt every 60,000K but here's hoping?!

They have a timing chain that dosent need changing and should last the life of the engine.

That's gonna explain a lot then Danoz, thanks though - I been beating myself silly looking for places that sell replacement belts and tensioners, might explain why I cant find them....! Doh!
