Is it an aluminum r brass rad?
Also, is the hole in a cooling tube or on one of the tanks, upper or lower?
Often a cooling tube can simply be pinched off to solve the problem. Loss of one cooling tube is usually not a big issue.
If you are soldering be careful about the amount of heat you introduce, use cold wet cloths in the adjacent area to act as heat sinks and work quickly.
The issue with to much heat is the possibility of creating a leak elsewhere due to other joints becoming unsoldered.
Good luck.
