You probably still have air in the system. You need to jack the front of the car up, when the engine is cool, and open the bleeder valve sitting on the coolant outlet of the head. Make sure when you open this, that water streams out the top. Close it back up, start it with the radiator open. Allow the car's radiator starts to open, when you can feel hot water in the radiator. Then close off the cap. If theres still air in the system after that, you need to repeat the process.

Oh and your sure you didnt put your radiator cap in backwards?

You don't have to jack it up. Bleeder valve is on the intake next to the upper rad hose. Remove the screw, fill coolant. Run engine let it dribble out and install the screw back in.

Dude hate to say it, might be head gasket. If it had an air pocket, it would flat out over heat, not run hot.

Good luck
