If there is no coolant left in the system, look for a puddle of coolant on the passenger side of vehicle- you may have blown a coolant hose, you may have a failed water pump, you might even have blown a head gasket. See if the cooling fan(s) spin easily- you should have heard them running when the vehicle was overheating.

With engine cool, release tension on the serpentine belt. See if you can wiggle the water pump pulley. If it wiggles a lot- that was the likely main point of failure. If it wiggles only a little- try spinning it while holding the belt off it.It should spin smoothly as you turn it, but it should not spin much at all when you try spin it. Any roughness is indication of bearing failure or something simlar.

If it seems okay, refill the system with water initially so you can see if anything has burst- water will leak out from burst hoses with ease.

If nothing leaks obviously, keep the fill cap off and start vehicle. If water is forced out - you have at least a blown head gasket. If it does not force out, let vehicle run until warm- you will have some expansion of the water, but you want to see that the cooling fan(s) turn on. If the fans do not, shut the engine down and let it cool.

If engine overheats and those fans were operating- how many miles on vehicle? If more than 150,000 miles, or 225,000Km, it is is probable the impleller ot the water pump eroded away. It does happen. And then it is a matter of replaceing water pump, draining out water and refilling with correct mix of antifreeze and water. Ans since you are that far into it- replace heater hoses and both radiator hoses, and any bypass hoses as well.
Do not drive this when it gets this hot ,you need the cooling system checked by a professional ASAP!!! or you will severely damage the engine if you haven't already.
