Did you put the right thermostat in it 180o, Sounds like the water is not circulating through the motor, Make sure the hoses are not collapsing , check the bottom hose also , Hope this helps.

Quit over filling the reservoir.
It's only suppose to be HALF full.
Either that, or you have a "hot spot" in the engine that is retaining heat.
This is usually caused by using water in the cooling system instead of coolant mix.
Over time, rust flakes build up in the corners and low spots in the engine. As the engine runs the water pump the flow of coolant is great enough to displace the heat.
However, as soon as the engine is turned off, the coolant at the "hot spot" stops flowing and begins to boil.
You MAY be able to do a back flush to remove the debris and alleviate the problem.

You may have it overfilled. Let the water pour out. The cooling system has a way of balancing if there is too much water in the system. Are you using antifreeze too I hope?
Just be sure to check it and be mindful on the level marks on the overflow tanks that say min and max and if you do this when hot or cold. Keep it at least just above the min marks.

You did not mention the thermostat
One of the cheapest possibilities.
And most notorious for overheating
Also have you ever started the car and looked to see if the hoses are collapsing under the pressure?
You may need a spring inside to keep that from happening also.
