stuck nuts. Please help

If the location allows these would get the nut off http://www.toolstation.com/shop/Hand+Tools/Mechanics+Tools/Nut+Splitter+Set+2+Piece/d10/sd180/p80007

Use plusgas rather than WD40. Also tightening is sometimes a good way to help loosen rusted nuts before undoing them.

All else fails bring the drill out and fix the new one with a thick cable tie (if the location/design is suitable for this and it would hold the radiator properly.)

Good advice, leave to soak overnight..;)

If you can access the threads, use a rotary wire brush with an electric drill to clean the threads up. Use plus gas it's much better than WD40. If it does start to free slacken just a little, and tighten again, apply more plus gas and slacken further again. By doing it in steps it reduces the chance of shearing the bolt.
Good Luck!
