Help needed!!!
 

Hi All!
While i was driving home tonight i could hear a whinning noise like a bad radio reception from a car stereo. Just as i got near home the battery light came on then all the other lights came on and the power steering went!! i made it home and had a look under the bonnet and noticed that one of the pulleys must of came loose and had fallen off!!!!!
Looks like it just bolts on but i could see its worn where its worked loose and the bolt is missing,i have had a look on the internet and it looks like its called a few different names ie-power steering pulley,cam pulley ect.So can someone please tell me what its called? I have got a 96 uk turbo and its the bottom pulley at the front,and also do they come with the bolt or am going to have some trouble trying to find one?
Hope you can help
Thanks

H I think I have now found the part am now looking for the bolt anyone got a spare or know where to get one from thanks
