Is this a small amount of white smoke or a lot of white smoke? If it is a lot of white smoke it could be a head gasket problem.
1. Do you have coolant in oil or vice versa?
2. Pull spark plugs and inspect for plugs wet with coolant.
3. Do a compression test and check for a low cylinder.
If you have issues in any of these points you will need to replace the head gaskets.
The ac blows cold and then hot while driven
If you can duplicate the problem parked, see if the compressor is running when it stops blowing cold.Could be low on freon, a faulty ac clutch, relay, or other electrical problem.

I have the same thing happen to my '03 super duty F-350 6.0 and fixed it. Grab the entire console unit, lights and all and just pull straight down. Start with the side opposite the front windshield. It is a bit hard, but there are clips holding it. Pull the one plug off that is powering the console. On the back there is a large black plate with a black plug on it and a smaller black plate with a red plug on it. You will be working with the larger one. Pull off a white plug that is on the side of this larger black plate also remove the black plug on this one as well. Next unscrew the black plate and open it up by gently pulling on the clips. Be careful as there are a few resistors that might fall out. These are the problem. Once you open it up, you will see four resistors that all look the same. These come desoldered and cause this problem. Get a soldering iron and just hold it on one side of the resistor. If you look at it closely, you should see that one side of the resistor is no longer touching the circuit board. Do this to all the resistor sides that are not touching the circuit board. Hold the iron on this point for around 4 seconds or so. After removing the iron, check to see if the resistor stayed down. If it did, move on to the next one. DO NOT push on the resistor to see if it is good, just look to see if it is touching the board. Put it all back together and you are done. I did this to repair mine and it worked great.
How do you change fuel pump
The fuel pump is located inside the fuel tank, you can either remove the trucks bed or you can drop the fuel tank. Both ways require helping hands and a set of jack stands and hydraulic floor jack to raise the truck and also to lower the fuel tank out. You will also need a Ford fuel line removal tool, available from any parts store like NAPA.

The fuel pump on that vehicle should be located in the fuel tank. You will need to CAREFULLY lower the tank and remove / replace the pump. Hopefully the tank is almost empty.
