Default Still having problems with that coolant system!

I bought a new cap....installed a new thermostat..added more fluid.....
I don't get it...things are going fine...I get the trucked smogged and a week later, things go to hell.
Since the smog it seems to take longer then usual to warm up and gets too close the high end of the temp gauge for comfort when it does warm up. (Not in the red yet.) I put more fluid in...bought a new cap and installed a new thermostat. ( So much for the Easy Fix! But thanks for the advice anyway guys!)
Whats weird that it the temp gauge stays well below the "C" long after the length of time it use to take to reach normal temp. And when it finally gets to it's normal temp the needle just shoots up to the middle . Not slow and steady. One sec it's cold. Then ZIP! it's at normal. Use to just creep up there. (This occured before I replaced the cap, t-stat and added fluid and still is happening...)
The over flow tank stays full now since I added more fluid. Doesn't go down. I read somewhere the hose has a high point that's higher then the radiator and air gets trapped in it causing poor circulation...I also read that the blades for the water pump can deteriorate quickly and that the particles from that can cause radiator problems along with the poor circulation. I guess when I first bought the Ranger last year I should have had the radiator serviced....say's Captain Hind Sight!
Now I'm concern that maybe the high RPMs that are needed for smog checks may have blown a head gasket. Has that ever happened? there a easy way I can check if that's the problem myself without taking it to a mechanic? Should I have bought the Saab?

I would start to suspect a blown headgasket at this point, but thats just me. I have never heard of head gasket being blown during a smog test, but perhaps something did happen for this occur.

try checking your water pump, it appears that some of the blades of the water are gone,if the temp gauge shoots quickly to normal operation,theres a weep hole on the water pump itself, if you see traces of coolant then its shot
