1994 Oldsmobile Cutlass timing belt tensioner

When reading this stupid question, please keep in mind, I am a girl! With that said, the timing belt tensioner on my 94' Olds Cutlass broke, but thats not the real problem. The real problem is that where the little roller-ball looking thing on the end of it goes into, it completely cracked off of where it was connected to the engine. My question is, is there a plate(or something) that connects to the engine that the tensioner connects to? In order to repair this, does the entire engine need to come out? Im sure none of this made a bit of sense, but on the off-chance that it did, I would be ever so greatful for any help offered. Thank you!
