(2014) ISX15 coolant help!

[Waterloo]

Two windshields in mine, bought the truck in 2013. That is close to 500,000 miles or there about. When you replace the glass, take it to a shop that can get the truck indoors to change out the windshield. Have them inspect the opening in the body, I bet there is something there that is hitting the glass and causing it to crack. I take mine to an outfit in Jackson Michigan, they get me inside the shop and according to the installer, it takes two men to properly seat the window in the opening. Just what they tell me, and the windshield installed ran around $140.
