My car is over heating. on 2006 Buick Rendezvous

My car is over heating. I put antifreeze in the radiator, but the car still does not sucks up all of the antifreeze and continues to over heat. I checked it for a leak. I could find any leak. What could it be?

Many possibilities for an overheat condition. Lack of coolant, stuck thermostat or electric cooling fans not working. Try turning on the A/c to see if the cooling fans activate.If they don't turn on , then possible bad fan motor,fuse, relay or computer.
