Pentofrost A2 is a phosphated organic acid technology (phosphated OAT); which is categorized as HOAT (hybrid organic acid technology) in the US market. Pentofrost A2 is suitable for all Asian vehicles using "green" Antifreeze/Coolant.
Pentofrost A2 does not contain any silicate, borate, nitrite, or amine additives since these may harm your Asian vehicle. Do not mix with other coolants (especially silicated coolants), as this may cause gel formation and clog your radiator.
Pentofrost A2 is an antifreeze CONCENTRATE for Asian vehicle applications in water-cooled engines. This must be mixed with distilled water. It contains phosphates and organic salts to protect all materials used in cooling systems
for Asian vehicles. Pentofrost A2 is mixable with all phosphated OATs. Meets ASTM D-3306.
Not returnable once opened.
Prediluted formula contains 50% distilled or deionized water, mixed with 50% full-strength concentrate, making it ready-to-use straight from the bottle.

Coolant / Antifreeze Says a lot about Cooling System Health!
Routinely inspect your Coolant / Antifreeze with these simple checks, and flush the system when necessary, to help prolong the life of your Cooling System:
COOLANT COLOR / CLARITY
Coolant should be bright, clear and free of debris. Dirty or brown coolant can be caused by:
Stray electrical current from a loose or damaged Battery Cable ground
Worn / old, acidic coolant
A reading of 0.4 volts or above suggests electrolysis
