I got a constant squeal when the car is warm or cold ive replaced the pulleys and belts the noise gets a lil louder when u use the A/C but that belt has been changed also. Any suggestions? Its only been a couple days since ive changed them over dno if they got to be worn in?
Wondering if its one of the accessories running off the main belt, the pulley squeaking? Eg. alternator or so? I also have a similar thing too, except mine usually cannot be heard after driving for a while, but it sounds terrible when coasting or going slow in streets or car parks I need sometime to diagnose it more, i'll keep watching this thread also.
