Does anyone know what the pulley itself looks like?

I've done a google/ebay search and i get a few different images....
I hear you could replace the idle pulley tesioner yourself....it's as simple as replacing the belts...
I'm less worried about labor costs/or the DIY? but I'm worried about the cost of the part?

here are two separate images I get for the search:

thanks...so 318i and 328i and 325i all have the same part?
I'm buying this used from a 1998 328i.

CHeck it out on realoem.com. I am going to bed now, so I won't do it for you. I would not bet on them being the same, but they may be.

Good luck.

Thanks ya'll,
Apparantely that is the pulley tension in the bottom pic is for the 328 cars. The top one is something that connects the altenator to the belt drive.
The 318i is only a wheel and not that metal part...

Projal who has the same 1995 318i sent me the picture...
thanks

it shouldn't be a hard job. you oculd do it yourself fairly easily and cheap (but maybe thats just me because i'm into DIY engine work)
