Polygard Anti-Freeze H-OAT Coolant is a proprietary blend of traditional and organic acid corrosion inhibitors and
additives in glycol that provides all year round freezing and corrosion protection to your engine cooling system. It
meets the performance requirements of most HGV OEMs and anti-freeze national specifications protecting all metals
commonly used in engine construction from corrosion and cavitation, including aluminium. It combines the protection
of traditional anti-freeze and coolant technology with the slower depletion rates of OAT formulations giving extended
anti-freeze life.

Directions
Polygard Anti-Freeze H-OAT 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 the minimum concentration used should be 33%
by volume and for heavy duty diesel applications 50% by volume is recommended. Consult engine manufacturers
recommendations before use.
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.
