Most common mistake I see people do is after installing a radiator they fill it up and go for a drive and wave goodbye to mom and pa thinking its all fine and dandy. Then it overheats 10min later. You have to fill it up to the brim, drive it around the block, pop the cap and there will be *alot* more room for more coolant to fill it up the rest of the way.
