180 sounds low, but t-stat fluctuations from 190 to 200 is normal. All my past CTD did the same as well.

Coolant wont fly out, just open the plug until you have coolant coming out and tighten it back up...... Not trying to offend anyone but make sure the truck is cool when you do this.

ya what you can do is fill the radiator until it gets full and then, if you can, let the truck warm up and get to normal operating temperature with the radiator cap off. When the tstat opens up you will see the coolant flowing. After a couple minutes of idling at normal operating temp (on flat ground) you should have all the air bubbles out.
