Question about 2003 Ford Expedition
Hi Sharlene,so you smell antifreeze.Raise your hood and check your antifreeze over flow container,you should have a l and a h mark on it,high and low.If low,then it's leaking somewhere,look at the radiator cap and overflow hose for leak,look at over flow container for leak from hose going to it from radiator,look all over engine,look at top and bottom radiator hoses and clamps for leaks,if leaking there,tighten clamp with flat head screw driver,if no leak is found,get under vehicle and see if any antifreeze is visible,maybe water pump,look on ground for leak and follow,check floor board on driver side,heater core could be bad,check hoses going to heater core from engine firewall.

You need to take it to a shop and have the system pressurized with a special tool.

If the coolant leak is on the pasenger's side then you have a leak in your heater core. The only way to fix it is replace it. Hope this helps.

Hi, a small leak in the heater core could either be draining through the evaporator drain port or perhaps just evaporating into the air flow. Does the windshield fog when you set it on defrost?

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.

This is likely the heater core leaking. Once it turns cold you will have foggy windows too.
When the heat is turned off the antifreeze stops flowing through the heater core, once it was all gone the leak would have stopped until the next time you need heat.
