Yes stock radiator and pump is good!
NO NO NO! Get a new or used fan! Fans are balanced to the maximum.. I know it seems you can get em straight but you CAN NOT! Don't even think about beating on them with a hammer.
Be sure to flush out the radiator that dirty stuff on the windshield should never have been inside the cooling system.
Living in Florida you can put straight antifreeze in there and not the half and half... Your new pump will last a lot longer with new PURE stuff in there.
