As memory serves, that would be a waterpump/drive issue.MYCADDY said:Hey guys, Im looking for some advise or any suggestions. I have a disturbing howling noise comming from underneath the left side of the front valve cover or the in the pulley system by the alternator area. Has anyone had this kind of noise comming from their northstar engine? Its pissing me off that a engine with 57500 miles on it is making this kind of noise. Your replies are greatly appreciated.
