I had this same problem start happening, and pretty soon it started bubbling just after short drives in the heat, and the car started to overheat as well. Changed the thermostat but the old one ended up being fine, same problem kept happening. After I had a new radiator put in it fixed everything. Might be the same thing for you, or it could be different. It would probably be a good idea to have it checked out soon though if you don't do it yourself.

I say after you hear the "bubbling" and stuff keep the car on. Pop the hood and watch all over the place for anything odd. I just had a similar problem this week. My temps went sky high and I saw the gauge go through the roof. I parked it on the road and opened the hood and saw that my upper radiator hose had swollen up to about twice it's size and within 10 seconds I had coolant burtsing through the water outlet. After I turned it off and releived the pressure the noise went away and I changed the hose and thermostat. Now everything's back to normal

Do a block / head test with that colored in the vial stuff just for peace of mind. It would suck to spend money on a radiator and all the other cooling stuff and still over heat. Break out the block tester man!

My exact thoughts. If it turns yellow, you gota BHG.
If not, could just be the thermostet. They're only 20 bucks, MAX.

if that's the only symptom, it probably isn't a BHG, but check for other BHG symptoms just in case (gurgling sound behind dash, overheating, oil looks like mud, etc). definitely change the thermostat, it's a $5 part that could melt your engine, I just chane mine every other year for the hell of it (make sure you get a good one tho, you can test in some hot water to make sure it opens). It could be your radiator cap. rad cap is designed to allow water out at a certain pressure and temperature, kinda like a thermostat. They wear out over time also and could just be letting excess coolant out of your radiator. i would start with a new rad cap and thermostat and see if that fixes it.
