New and used coolant can be hazardous.
Children and pets may be harmed by new or used coolant.
Continuous or brief contact with coolant may be dangerous for your
health.
Keep new and used coolant away from the children and pets. To
minimize your exposure to new and used coolant, wear a long sleeve shirt
and moisture-proof gloves (such as dishwashing gloves) when you
change coolant. If coolant contacts your skin, wash thoroughly with soap
and water. Wash any clothing or rags if wet with coolant. Recycle or
properly dispose of used coolant.
Harm or damage may occur if using coolant does not meet the
specification that is 50% standard green coolant and 50% distill water.
