Notes:
1. Consult with your representative or distributor if you have any questions regarding antifreeze selection or use.
2. Some antifreeze suppliers and manufacturers recommend the use of either de-ionized or distilled water with their
products. Some brands are designed to work with tap water. Consult the antifreeze manufacturer’s technical data.
