Directions
Polygard Anti-Freeze BLUE Coolant is suitable for use in all climates and provides year round corrosion and freeze
protection. When diluted with clean water it can provide freeze protection as low as 70C where extreme winters are
usual. To ensure satisfactory freeze and corrosion protection it is recommended that the minimum concentration used
is 25% by volume.
In all climates, alongside protecting the engine from corrosion, Polygard Anti-Freeze BLUE Coolant offers excellent heat
transfer properties, and minimises the risk of radiator overheating, by raising the boiling point above that of water alone.
The following freeze protection data should allow the end user to decide the degree of dilution necessary for his or her
situation. Use only clean water to dilute the anti-freeze and NEVER use at concentrations greater than 70% by volume.
