Pentosin 8115207 Engine Coolant / Antifreeze

Pentofrost A3 Blue Coolant for Asian Vehicles

Pentosin Pentofrost A3, part number 8115207, is a blue engine coolant and antifreeze formulated for Asian vehicles that specify a phosphated OAT or HOAT-style coolant. It is pre-diluted for direct use and meets ASTM D-3306 for passenger vehicle cooling systems.

• Phosphated organic acid technology for Asian vehicle cooling systems
• Blue coolant formulated for Honda, Acura, Nissan, Infiniti, Subaru, Mazda, Toyota, and Mitsubishi applications
• Pre-diluted formula for convenient service use
• No silicate, borate, nitrite, or amine additives
• Protects against corrosion and cavitation
• Does not foam during operation
• Meets DIN and ASTM D-3306 specifications

Application and Fitment

This Pentosin coolant is specified for many Asian-make vehicles that call for blue antifreeze, including Honda Civic, Honda Accord, Acura MDX, Nissan Rogue, Subaru Outback, Mazda CX-5, and similar models listed in the fitment data. Part number 8115207 is also referenced for a wide range of Honda, Acura, Nissan, Infiniti, Subaru, Mazda, Toyota, and Mitsubishi vehicles across 2012-2026 model years.

For Mazda vehicles that require blue coolant, the cooling system must be completely flushed before filling. Do not mix this fluid with silicated coolants, as improper mixing can cause gel formation and radiator restriction.

What This Coolant Helps Address

• Corrosion in aluminum and mixed-metal cooling systems
• Cavitation-related wear in water-cooled engines
• Foam formation that can reduce cooling efficiency
• Service issues caused by using the wrong coolant chemistry
• Radiator clogging from incompatible coolant mixing

Installation Notes and Tips

Drain and flush the cooling system before filling if the vehicle requires a blue coolant changeover, especially on Mazda applications noted in the fitment data. Use only where the vehicle specification calls for a phosphated OAT or HOAT-style blue coolant, and avoid mixing with other coolant chemistries unless the manufacturer explicitly allows it. Verify the vehicle’s service specification before topping off or refilling.

Quality Assurance

Pentosin formulates Pentofrost A3 to OE application-specific requirements and to the stated DIN and ASTM D-3306 standards. The formula is made without silicate, borate, nitrite, or amine additives to align with the needs of many Asian vehicle cooling systems.

This part cross-references Genuine Toyota (e.g., 00272GTBC1) for the same application.
