ADDITIONAL BENEFITS:

It is an Idea for sealing small holes and does not discolour existing coolant. One application can fill most radiators' gaps until a permanent repair can be completed.

APPLICATION:

Add one bottle to the Radiator and replace the cap; the water leak should stop within 30 seconds.  If the leak persists, leave the lid off the Radiator until all leaks have stopped, place the radiator cap back on, and check again after a few minutes for any other leaks.
