It could possibly be the thermostat or the cooling fan. Let the engine warm up and when it gets to 232 to 235 degrees the cooling fan should come on. If not you need to go from there.
The engine is overheating.
your vehicle may smell like antifreeze while driving because it is overheating
antifreeze keeps your car from overheating, it flows thru your radiator hose, without it your motor would blow
a leak is probably getting on something hot and cooking away
Antifreeze/Coolant is a fluid that prevents the car from overheating or becoming so cold that it won't start. Without it, in the summer, your car would run too hot, and in the winter, your car wouldn't run at all.
It means the car is overheating.
First you have to determine the cause. Could be a faulty thermostat, frozen coolant (insufficient mixture of antifreeze), low on coolant or possibly a bad head gasket.
If it is a vortec engine, it is probably the lower intake manifold gasket. In most cases you can smell it when the engine is hot.
First, are you low on antifreeze? If you aren't, did you reset the computer? I'm not an expert on Fords but there may be a little fuse box. The blinking one (if there is) is the one you reset.
Probably a blown head gasket. Get a technician to look at it. If it is, it will be a major ordeal.
It depends on if you see the antifreeze leaking or it is just disappearing. If it is just disappearing then a bad head gasket or cracked head may be the problem. The smoking could actually be vaporized antifreeze. If that is the case don't run it until you can get it fixed.
the heater core could be stopped up, or could be low of antifreeze, or the thermostat could be stuck open
