[Healeys] radiator leak

[Len and/or Marge Hartnett]

I have alway been leery about putting a stop-leak in the radiator.  If it 
will plug up a hole in the radiator, I have felt that it could plug up other 
holes in the cooling system such as the water passages in the block and 
head, the heater valve(s), and radiator drain valve.  I would only do it as 
an emergency measure, repair the problem, and flush the cooling system ASAP.
