My Sedona is suddenly overheating and coolant is coming out of the overflow tank. I really need help as to what this problem may be.

Check if the cooling fans are working.

I was told that they aren't. Today I noticed that a little switch was turned into a different position. I switched it back and could hear the fan running then. I drove it around a little bit. The gauge went over the middle mark. It didn't run hot as fast but I did notice that I was low on coolant. So I just left the van alone until I could get coolant tomorrow.

Seems there is a problem with the cooling system and someone has rigged a switch to turn the cooling fan on. Remember to bleed the system once you top up coolant and check for leaks which could be why you were low on coolant.

Hello there. I have a Kia sedona 2002 and I encountered the same problem you have. You will not believe it the cause was a faulty radiator cap. Just as simple as this, so I went and bought a genuine Kia cap put there and that's it, all done.
Just try it and I'm sure it will work

Yes, a pressure cap will make a big difference it does a very important job in the cooling system, with applied pressure the cooling system boiling point is raised, Water boils at 100DegC at sea level, add a 15Ib cap and it will raise the boiling point to around 121Deg C so cooling systems can operate at higher temps with out boiling, but each engine is designed to run at a specific temp so the correct thermostat and cap are very critical to correct cooling and maintaining operating temps.
