Don't waste your time with that.
The plastic parts of the cooling system have cracked. They'll have to be replaced. At a minimum, you need the coolant outlet pipe and thermostat housing. If you are smart and don't want to go through this again next month, you need to also replace the two main radiator hoses (both have big plastic sections) and the degas bottle.
You should never continue to drive an overheating car till it goes into failsafe mode. That's a good way to ruin an engine.
Cars don't spray coolant just because they are overheating. They only do it if there is a leak. A leak will cause overheating. (Yes, they can vent coolant from the degas cap pressure relief, but that's no where near the front of the engine.)
