Auxiliary belt is starting to squeal so i guess i'll need to get it changed. Just want to know how much it costs and what exactly gets changed. Just the belt or do the tensioners and idlers get replaced as well??
If its the 16v twin spark its a pretty easy DIY job. Change the tensioner pulley as well, and ideally but the idler pulley too. There's usually a plastic panel that needs removing in the wheel arch and space can be a bit tight, but nothing too tricky.
