Coolants & Antifreezes

Category Description: Coolants & Antifreezes

Coolants and antifreezes are critical engine fluids designed to regulate operating temperature, prevent freezing and overheating, and protect cooling systems from corrosion, scale, and cavitation. Whether for passenger vehicles, heavy-duty diesel fleets, or industrial equipment, the right coolant ensures reliable performance and extended component life in extreme operating conditions.

Our Coolants & Antifreezes category includes ethylene glycol and propylene glycol formulations, available in conventional, long-life, and extended-life technologies. These products meet or exceed major OEM and ASTM specifications and are offered in concentrates and prediluted mixtures for automotive, heavy-duty, and industrial applications.

From modern OAT and HOAT coolants for late-model vehicles to extended life coolants (ELC) for diesel engines, this category delivers proven protection for radiators, water pumps, cylinder liners, and heat transfer systems—helping reduce maintenance costs and prevent costly downtime.
