Either an air pocket in your cooling system or waterpump is bad. for air pocket, jack up the front end of the car where the radiator cap is, start car, and keep adding fluid till full and blowing warm heat. note, might have to squeeze upper radiator hose to help get the air out. if doing that dosn't help any, odds are you need a new water pump.

Here is alot of info go through it and I hope ypu will fine the problem. Check to see if your head gasket is bad. With the engine cold start it grab the radiator hose (watch your fingers) squeeze it when rev up the motor a little, If the hose becomes harder the head gasket is bad. now make sure the anti-freeze is bleed out by letting the radiator cap off and add it it is full. Also after that get it hot about 225 deg normal operating temp. and make sure the fan is working,if it is and the head gasket you will need to check the water pump.
