Thermo is still a possibility, but I would pull the spark plugs, pump the cooling sys up with a pressure tester and see if coolant gets in cylinders. Pressure tester is a real handy tool to have, even if it's only once a year or less. Sometimes the bubbling radiator is a little misleading, unless it's really blowing out of there. I just had a 4.7 here that ran a little rough cold, used a pint of coolant in 50 miles, put pressure tester on and pumped it up twice a day and after 3 days showed cyls 1 and 3 were getting coolant.  Now if the PT's have head gasket issues routinely, have at it.

the new stop leak stuff works!! i can't remember the brand, but the stuff was expensive, about $30. we have a beater van where i work, and it is just used to take the mail one block away twice a day. sprung a leak external to the block and internal (coolant bubbles/loss). we figured what do we have too loose, dumped in a bottle of this copper looking stop leak, ran it for 30mins idle, refilled coolant, that was 1.5yrs ago, and the van has actually been driven some distances for delivery ect....it completely stopped leaking and there is no coolant loss. i was amazed!! BUT you have to be sure your problem is the head gasket, and factor in if it's worth fixing properly, in your case a fairly new car, that you rely on to go to work...ect...maybe it's wise to replace the head gasket (if that is the problem). I'd check the simple things first, I've had a car do what you describe with a stuck-closed thermostat. You could also have a hose with a hole in it sucking air/collapsing hose, ect..... i'd do some trouble shooting first before concluding a head gasket, check the plugs, ect.... but in a pinch, the stop leak stuff worked. this was in a 2001 GMC safari van with 400000kms, has about 50000kms since the stop leak stuff with no sign of leaks. it was not worth fixing if it actually needed a head gasket as it is high mile rusty and basically junk!!! but it's still going strong!!!

I used this last fall, 8 months ago in a 4 cly forktruck motor. It get's worked pretty hard each day especially here as of late when it's 100 degrees out.
A another mechanic friend of mine recomended it to me and said it works great permently. So far he has been right. 
It's get's used differently than other sealers I have used, got to follow the directions exactly is what he told me and I did, stuff worked for me.

6 headgaskets jobs to a case. How many engines got repaired with that stuff and the customer got billed for head gaskets? The guy who told me about it I have known 30 years, now he's retired. I bet that why he "spilled the beans. 
I found it on the shelf at Car Quest.
