If it's spraying out of the spout and is boiling, it's very possible that one of the head gaskets blew depending on how long it takes to overheat.
A few things to look for:
Inspect the radiator. Make sure all of the cooling fins are there, and not obstructed by dirt/debris.
Make sure the cooling fan is turning on (it should turn on when the temperature is approximately at the halfway point of the temp gauge).
Look at the color of the "smoke" coming from the tailpipe. White = steam. Some steam is normal, however, if it's constant, and a lot of it, it's a blown head gasket indicator.
Blue = burning oil. Black = unburned fuel,
probably either the intake manifold gasket, or a head gasket has failed allowing cylinder compression to escape into the cooling system and boiling the coolant. also look for milky oil(water in the crankcase), or for oil in the coolant system(rainbow sheen on top of coolant in the radiator, or overflow reservoir).
you have a blown head gasket.. doesn't have to have coolant in the oil for a blown head gasket... if hoses are rock hard when running then you have exhaust leaking into the coolant via a blown head gasket...
Either the thermostat is stuck in the closed position...or the engine cooling system cannot pressurize...both will cause an overheat condition.
A blown head gasket can cause overheat condition as well as fluid loss (boil over)
I'd maybe remove the thermostat and either just replace it or not have a thermostat installed just to see if it still boils over. If it boils over with no thermostat installed then you're getting into possible leak in cooling system...i.e. water pump weep hole, hose or radiator leak...or a blown head gasket.
The stop leak most like caused the thermostat to stick closed and caused the over heating which may have blown a head or intake gasket. Have the oil analyzed to see if there is coolant present and if there is you will need to determine which gasket needs replaced. On newer vehicles it's no small job to replace a head or intake gasket os special tools are required.
head gasket failure between piston seal and the cooling system causing pressure ,it will not show as water in oil but white smoke on start up from cold ,when it warms up it will tend to seal itself but eventually it will just keep boiling up
As you've stated driving around town it's fine, and everything is working well. For the symptoms, there are 2 possible causes: 1. Your cooling fans are not working. 2. Your radiator needs to be replaced. I'm sure you can determine which it is, and I wish you luck on your repair.
If the engine overheated for any length of time, it may have some fried rubber hoses and worse, a blown head gasket.
If the latter has occurred, in the next couple of hundred miles, oily deposits may show up in the coolant overflow bottle or an emulsion of coolant and oil on the dipstick. This will look like dirty hand creme if it happens.
If the gasket fails badly enough, there may be leakage of oil or coolant on the block below the junction with the head.
If the gasket fails between cylinders, the engine may seem really tired or misfire and eat fuel.
Worst case; damaged piston rings, rod and crankshaft bearings along with damage to other seals and gaskets.
For right now, I would make sure the cooling system gets tight again, the oil is changed (it may have chunks of burned oil in it) and drive conservatively with ears open and NO MUSIC for a few days to listen for irregular engine noises that could be caused by the engine damage described.
