The only thing you can do is to try and purge the cooling system from air pockets that is a must when refilling with coolant after changing the radiator. But there may be a bad water pump or blown head gasket, you would notice a lot of white smoke out the exhaust with a sweet smell. So try purging the coolant system, here is a video on how to do that... www.youtube.com/watch?v=zUpXgAJ1gjU
