1998 Expedition: 2000 Ford Expedition I smell antifreeze with heate...

If you smell antifreeze it may be 3 possibilities: 1. you may have a leaking hose/hose connector , or water pump. 2. your heater core is bad and needs replaced. Unless you know what you are doing I would highly suggest taking to dealer for heater core replacement. The dash and steering colum has to be removed to get to the heater core. This is not an easy job believe me (about-900-1200 job). If you have your heater core replaced then also replace the climate control door. This is good preventative maintenance and also a a dollar saver. I would have a pressure check run on your radiator as a first thought. All you may have is a bad hose and that can easily be replaced.
