Hey all...Any thoughts on what could be causing a humming/whining almost scraping noise around the belt assembly on my 96 Integra as it idles? I recently had timing belt, water pump and accessory drive belts replaced. I am not sure if belt tensioner was replaced for it does not sound like grinding. I suspect maybe a pulley or alternator. It is intermittent and does not occur under any specific conditions. It is only noticeable when car is idling and not under any load such as reving. Any help would be appreciated. Thanks all.
