If it overheated that easily, then there's probably an air bubble in the coolant system. Those can be very difficult to bleed.

For mine, I finally resorted to putting the system under a few PSI of pressure with a cooling system pressure tester, then cracking the lines at the heater core (high point of system) until coolant came out. Not perfect, but better than anything else I had tried.

When you get a chance, you'll want to check that the cooling system and cap holds pressure (~10 PSI). It won't overheat very fast even if it doesn't hold pressure. Seems like I'm fixing mine every few years.
