just bought my 3rd v70 t5 2005 plate with 180k on the clock yesterday with this problem.. under acceleration from 2800 to about 3500 rpm there is a rattle! sounds like its coming from the aux belt area somewhere. its there when I rev the car from stationary too.. any help with diagnosing it would be greatly appreciated thanks ...
I had this issue the other day, sounded like my turbo was shot, changed that, was still there, turned out to be a snapped exhaust bracket rattling on the exhaust. Only thing i could suggest is to get it jacked up and have a nose around, hit a few things with your hand see if anything is loose and causing the rattle
cheers dan. had the aux belt off this morning and spun each pulley. I did notice that when I spun the a/c compressor pulley there was a sound like bells!...?? and the tensioner pulley had a tiny bit of play in it. will get it up on the ramps today and have a good look. cheers..;)
FOUND IT !! I have sussed it that it only occurs when the engine is warm. so again took the aux belt off.....started the car...NO RATTLE/SCREECH ;) sprayed the a/c compressor pulley with copper slip refitted the belt NO RATTLE/SCREECH it was noisey just before I switched off to take the belt off. im wondering now if its possible to just replace the pulley or am I better replacing the the whole compressor with pulley? I can relax now as I was beginning to think it was in the timming belt area! :funkybana
