Adding coolant and no apparent leak?
Overheating fairly quickly?
Sorry to say the head gasket or head is likely cracked

Cracked head or head gasket rupture

Combustion pressure is bleeding into the cooling system.

With the car cold, open the radiator cap, or "Coolant bottle cap" (Not sure which you have) fill with water, and start the car. look for white or light gray smoke from the exhaust, and bubbles in the coolant filler.....

If the head gasket/head is bad enough, when you do Uncle's test you'll get a geyser out the filler. Would this be a 3.8L engine by any chance? Known head gasket blower.

3.0L better than the 3.8L. May or may not see it at tailpipe depending on where the blown part is and how bad. How's the oil look?

3.0 I believe to be a Cast iron cylinder head, as opposed to the 3,8 mentioned, that being aluminum.

The smoke is hit or miss......

Cooling system pressure is 15 -17 at most, but the pressure in the combustion chamber can reach in excess of 200 -300 pounds. The coolant will not overcome combustion pressure, so it wont leak in until the engine is shutdown and combustion pressure ceases. You would only see the smoking tailpipe after a "Sit and Soak" period, which is why I mentioned "With the car cold".. Most engines dont leak head gasket externally (I have only seen 3 .0 MItsubishi motors leak externally from a head gasket failure) So your options are either into the oil, or into the chambers.

Look at the motor oil, If it looks like chocolate milkshake, you have your answer.

oil is fine not milky, clean and clear. im used to being able to look at the radiator cap and wait till the thermostate opens and you can see the water moving, which tells me the thermo and pump is working. im not familar with the fill /overflow plastic container which is in this ford .how can i tell if the water pump is working or the new thermo is ok
