An old bicycle inner tube can be cut opposite its valve and the now open ends clamped onto a radiator's inlet and outlet. Install the radiator cap and use a hand pump to add a pound or so of air through the tube's valve stem. A spray of soapy water will reveal the holes, which may then be soldered and the process repeated until all the leaks are stopped.

That is a pretty cool idea. Thanks for sharing!!!

Slick!! Thanks for sharing!! Got two to check!!

Brilliant Idea!! and that idea could be applied to other things eg old boilers and things that need to hold in water/fluids
Now why didn't I think of that!!
