You're easy money.
I replaced my serpentine belt about two years ago with a dayco one from pep boys, around the same time too because I remember doing it after my last final. When it's cold and I start the car the belt squeaks, until the engine is warmed up. Recently in New York we had some nice weather and the belt was fine, but whenever it's cold and dry it squeaks. There seems to be no cracks or anything on it. Can I spray belt dressing on it? I hear that stuff is actually garbage, does anyone know what the problem is?
