Do all Tercels have drive belt tension pulleys???

What is your question?

the reason I'm asking is my 97 Tercel had 2 tension pulleys on it but after i had some work done to it i noticed it now has none. In fact the whole pulley set up does not look the same??? the guy said he replaced the crank because it had some a few broken teeth on it. I'm really confused, I know i don't much about motors but i do know it doesn't look the same under the hood, please help!!!
