My sister owns a B7500.. I'm guessing a 2003-2005 era model. Well... They have not taken great care of it and at some point in the past, filled the radiator with water and not antifreeze. .. This past winter a freeze plug popped and I assumed it was just the plug. They replaced it but when they filled the coolant again..... It filled the crank case. ... Engine is all done. Any idea what a short block runs for one of those ?
