My radiator in my '96 DC4 has started to leak. After a while of searching for the source of the leak, it looks to be 3 tiny holes next to each other (The holes are about 1mm in diameter, and located within 3 centimeters of each other) which are spurting out thin amounts of coolant, and eventually running the radiator dry.

Anyway the leak is located right at the bottom of the radiator on the plastic part. Is there anyway I can seal this leak permanently? For now I'm using duct tape which was good for about a week, but eventually the pressure tore off the tape.



My radiator looks similar to this and the holes are right at the bottom were the plastic is.
