Another way to get air bubbles out is to put the car on ramps and turn on the heat and rev it to 2500 for like 5 min, they sell a funnel with a Rad cap adapter on it that lets u keep the Rad over filled and allows coolant to go back in if there's air in the system

Are you fans turning on? If not, check the two wire coolant temp sensor, could be loose or you might have a short somewhere. Also make sure you're bleeding the system properly. I will usually fill the system up, leaving the radiator cap off and turn the car on. Then I'll squeeze the inlet hose to squeeze some air out. Once the thermostat opens I'll top off the system then watch for bubbles, then once no bubbles are present I will replace the cap then I'll use the bleeder screw on the thermostat housing to remove the rest of the air. I've never had a problem by using this method.

check your single wire coolant temp sensor.

Yeah I have a problem with mine overheating too, the fans never turn on. I have replaced the coolant sensor, temperature sensor switch and thermostat. The fan relays are fine and only turn on when my coolant sensor is unplugged but if I do that my motor idles really bad.
