Bought this for my wife last year with 50,xxx. Two weeks later had radiator leak. Lucky the dealership replaced radiator at no charge. Here it is less then a year later and radiator is leaking once again. Again lucky the radiator that got replaced had a 1yr warranty. Turns out 2006/2007 4.0L explorers have a tech service bulletin for a PCM (Power Train Module) update calibration. If you have a 2006 Explorer, Mountaineer or 2007 Sport Trac I would get this updated before you have to replace a radiator if you haven't already. This TS bulletin was released 5/4/2009 so just a heads up to anyone having trouble with radiators leaking. $100 for software update or $$$$ for a new radiator.
