need real help

[jloster]

I need to know how to replace the idler pulley,how much it is and can I do it myself?

[95-J30tt]

do you mean the idler pully for the AC??, if that is it, then it is very easy to replace, always check if the bolts are tight first before you go ahead and replace it (if it is loose, it could be that it is just not tight enough)

if i remember correctly, you will only need a 14mm and a 12mm sockets for the removal, try to find a replacement at a junk yard (300zx or J30 or 300zxtt, they all have that eact same part). not sure how much it would cost at the dealer, but it shouldnt be much..... i hope this helps, good luck
