sounds like a stuck thermostat

If the cooling system had enough pressure to blow off the top radiator hose, you may have a cracked head or block.
I would take the thermostat out and run the engine without it to see how hot it gets and how much pressure it builds up. Be sure and check the radiator cap too.

Thermostat?

aluminum radiator
plastic top and base seal
tanks held in with crimps on aluminum radiator

find a local radiator shop to replace top seal and top plastic part
of that radiator
not as expensive as a new radiator

replace the thermostat

pressure is too much on that crack for any diy repair product

pop off hose at the wrong time =cook the motor

The engine must be running to add coolant to a hot engine. When your water hit the head/block it vaporized and blew back. The engine is probably OK even though it probably lost some coolant and got hot.

First place I'd look is at the thermostat. However, if the hose did not rupture in a normal manner and blew apart, I'd also suspect that you may have a blown head gasket. In that case, compression is entering the cooling system which is not designed to handle such high pressures, therefore causing the hose to explode). This will also result in rough running you observed.

you've got a serious overheating issue creating the pressure. Your temp gauge must be reading hot too.
If not, then you have engine compression pressure getting into the cooling system through a blown head gasket.
Replacing the cap will not help.

are you sure you had installed the correct gasket? did you compare it with the old gasket that you took off? I suspect that you got the wrong gasket and blocked up the holes between cylinder head and engine block thats why the coolant are not circulating thus creating an excessive heat

I had the same problem today with my sunfire 96 2.2L and it was the radiator fan that was draining too much amperes and the fuse blew up 3 seconds or less after the fan was turning.... i just change the radiator fan motor and the fan and the fuse are ok!!!!
