Well its done and the old one was ready to fall apart,took 45 mins from start to finish,olny because i had a tool that removed the bolt from bottom pulley with no problem.(cordless drill special )the only problem i have at the moment is how do you get the right tension on the fan belt?i did it in the end with engine running and just kept doing it up untill it stopped makeing that noise, when belt is too lose,well lets hope i have done it up to the right place,unless some kind sole has the gauges that they use to do this thing with that can do mine for me.(dont know unless you ask) thanks for putting up with this rubbish about the pulley all this time , chris .
