why is my car overheating have tried everything i can think of please help.. on 2000 Oldsmobile Alero

i also changed the water pump and car still over heating some white smoke coming out of tailpipe assume bad head gasket so i bought some head gasket sealant still over heating but now we noticed the fans are not coming on until the car is actually over heating or not at all so i am curious if anyone knows how to wire up a toggle switch directly to fans any help would be great thank you, please note that this car broke after just 1 1/2 wks of putting money down on this car had not even made a first payment... now the gentlemen at the car lot say we will fix and add it to your bill ha ha ha... looks like we got scammed good i do think what about you...
