Sounds like there is a clog somewhere. Either the thermostat is stuck closed, or the radiator is clogged, or the water pump may be defective. It could also be that the bottom radiator hose is "soft". When this happens, the hose can pinch itself shut like when you drink a thick shake through a straw.

With the engine cold, reach under the car and try to squeeze the lower radiator hose shut. It should be rigid and un-squeezable. If you can squeeze the hose, replace it.

Check Your thermostat replace it. Did you clean your engine our and have your radiator cleaned by a pro. Keep your new antifreeze and before putting it back in pour it thou a clothe to stop any dirt or rest from getting back in. Also you might have a leaking head gasket pull your plugs and look at all of them.

I'd be willing to bet that the only problem you've got is a little air pocket in your cooling system.

This is easily resolved by just burping the air out of your cooling system.

If this doesn't resolve your cooling system problem refer to the second link below.

Best of luck.
