Make sure the radiator fan is coming on. If the fan comes on and its still overheating then i would change the thermostat and go from there.

Did you install the thermostat facing the right way? Check that the Radiator is properly filled and doesnt have crap in it. You could also have air somewhere in the system
Are you referring to the overflow bottle? And where exactly is this hole the coolant 'shoots through'? The rad cap needs to hold pressure to 16 psi otherwise the coolant will flow into the overflow bottle as soon as the engine warms up. How did you test to ensure there is flow though the rad? Once the T-stat opens the top hose should be rock hard. How does the coolant look? Bright green or rusty or something else.

I believe the radiator fan has a low and high speed. The high comes on at hot temperatures, make sure it kicks on and isn't just the slow one. Consider a radiator fluid change if it's old, it's less effective.

if its the right 16 psi cap you might have a water pump problem. i have heard of pumps being pulled because of o/h and nothing left of the impeller. fan should not be the isue if your driving when it overheats unless your way into the power and it wont kick on. if pump wont fix it test coolant temp sensors on the stove.
