Not unless the problem is large enough, and by then it's usually to late! BLOCK test the radiator, this test sniffs hydrocarbons in the coolant, if they are present there, then there is a gasket or head problem. If it's only a very slow leak, check the freeze plugs on the bottom of the sides of the block, that's were the corrode.
