my car has started making a squealing noise in the mornings or after it has been sitting for a while. at first i thought it was an idler pulley going bad but now i think it is the belt. i can spray the belt with WD40 and it will quiet down for a few seconds and then start back making noise. once it has been driven for 10min or so there is no noise at all till it sits again. anyone else ran into this?
