By simply pouring it into the radiator, it covers over the hole or crack and stops a leak. If you pour it in advance, it prevents the radiator from those troubles.

Directions to use

* Be sure that the engine is stopped.

1. Shake the bottle well, take off the radiator cap and pour the liquid into the radiator. Afterward fill the coolant to the right level.

2. Tighten the radiator cap and turn on the engine to let the coolant circulate inside. The leak stops as soon as that.

3. If you use it to old radiator, remove rust or dirt in advance.
