Prestone bug wash
My pump failed shortly after using the Prestone bug wash. 3 days after I filled the reservoir because it was on sale, I tried using the wipers to clean off some bird droppings, there was no hum. When I stopped at a light, it started leaking, apparently someone in the next lane honked and said I was dripping fluid from under my car. I pulled into a station and popped the hood, the fluid was all gone. I went online bought a replacement pump and installed it in a matter of minutes. Prestone Bug Wash Nevermore!!!
