well in fact me and my buddy did loosen it, then pulled the alternator (?) and re-tightened the bolt, he then sprayed some engine lube or something on it. it hasnt really made the noise as much, but maybe ill get it changed if its inevitable anyway. any brand of belt better to use? or just the standard toyota dealership what-ever-they-charge belt brand
