I was snooping around in my dad's garage looking for window washing fluid, when I found a product that supposidly decreases the noise coming from your engines belt. It also read it would extend the life of your belt. What could it hurt to spray a little on my belt to extend the life of my car? One hour later it now sounds like one of those annoying locusts got under my hood. The car makes the sound whenever the car is on no matter what. I tried sparaying WD40 on the belt, but it only stops the sound until the WD40 wears off. Please help
