I had the same thing with a fairly new radiator that i had put antifreeze from old radiator. then it sat for 2 years while i finished it and the stop leak that was in the old radiator hardened. tried everything to get rid of it, finally bought a new aluminum and that did the trick. i also put in a high flow thermostat that i got at Auto Zone.
