Are you sure it is overheating or is the temp sensor bad. A bad sensor will tell the ECM the engine is hot and the ECM will retard the timing and richen the mixture along with other thing like turning on the warning light....make sure it is actually overheating

Sounds like you have air in the cooling system. There's a bleeder screw on top of the thermostat housing that must be opened up while filling the radiator. It's also helpful, if possible, to fill the cooling system with the front of the car on an upward angle. Like halfway in the driveway for example. HTH. -Jim
