in the past week or so i've been noticing a sqeaky belt under the hood and didn't think to much of it cause usally after about 2-3 minutes it would quit but now it does it all the time. it's loudest when i first start up the car and get's louder as i go faster. anyway it seems to be coming from the power steering belt but it could be the altenator belt since there so close together. but my question is should i replace the belt or does the pulley need to be replaced or just some kind of lubricant put on it? thanks guys.
