tension pulley question

Hey guys first time on this forum, I have a 1993 Pontiac Bonneville SSE, and I'm thinking about changing the tension pulley on my car, and since I'm only learning as I go, I have a couple questions that might seem pretty dumb.

1. Is it normal for the pulley to shift sightly left and right while the car is running,

2. If I do change it because of that reason, should I expect the pulley to pop out at me or anything as I unscrew the bolt? I have a nightmare about trying to get that done by myself, and losing an eye or something stupid.

If anyone can help out that'd be great, I know this is an awful question, I just don't know any better yet.

Here's the procedure.


No, the pulley should not move appreciably. Once you relieve belt pressure you can safely unbolt the tensioner and pulley as a unit. The spring portion is self-contained in the assembly.

Also replace any idler pulleys the vehicle might have; they fail at least as often as the tensioners and will destroy a belt just as fast.
