As the colder months are coming washer fluid if not mixed correctly can and will damage your washer fluid system by freezing. When freezing it will burst the lines, tank, nozzles, and pump. Make sure the washer fluid is good to at least 0 degrees. There are alternatives at most auto supply stores and retail outlets that are formulated for the winter months. These alternatives have more alcohol or antifreeze in them to help in window deicing. Never put water in the washer fluid system during cold months.
