well here we in NH 1700 miles from home in FL and the second radiator failure in as many years. Newell first replaced radiator with a new Atlas Sept. 2011, radiator failed Oct 2013 and Creative Coach replaced with a new Atlas radiator; now Sept 2016 radiator failure again. There must be a cause for this so the radiator lasts more than 24 months, Atlas disavows all responsibility, despite my insistence that regardless of warranty period the radiator should last ten years approx(the original radiator in our 1999 Newell was 12 years old when it failed). We monitor pH and change the coolant filter once a year. Same failure problems appears to be corrosion along the bottom of the radiator.
Need help from anyone out there with same experience or a knowledge base.
Thanks
