Lesabre Belts

Now this may sound stupid but i was talking to someone after my serpintine belt tensioner broke and they said that there are 3 belts...is this true? they said timing chain, fan belt and s-belt, i knew about the latter two, ... im confused..can some one just clerify this..thank you:eek7::eek7:

There is a timing chain...to read about it just google "Lesabre Timing Chain" and a bunch of things come up...hopefully that helped!
