Anti-Freeze has ability of cooling, anti-freezing, anti-boiling, anti-rust and anti-scaling. It will prevent water in tank from freezing at very low temperature, or boiling at very high temperature to protect tank and engine. 

USAGE DIRECTION:

1.Drain out existing coolant or anti-freeze and rinse out the inside of radiator.

2.Pour in the specified amount of this anti-freeze, then add more until the liquid level becomes visible and run the engine at idling speed for about 5 minutes. If the liquid level falls, add water so as to bring the level to about 3cm (about 1.2 inches) below the overflow pipe. Be sure to observe the specified level since the coolant expands as the temperature rises.
