Pentofrost SF Lifetime Anti-Freeze/Coolant For Aluminum Engines (1.5 L)

European vehicles with aluminum cooling system components need a coolant that will not eat away at the metal over time, and Pentosin Pentofrost SF is formulated specifically for that job. This 1.5-liter G12+ concentrate uses Hybrid Organic Acid Technology (H-OAT) to protect against corrosion and cavitation without the silicates, phosphates, nitrites, or amines found in many conventional coolants.

Pentofrost SF meets DIN and ASTM D-3306 specifications, and its phosphate-free chemistry makes it a direct match for vehicles that call for G12+ coolant — a common requirement across many European makes. The pink-colored concentrate mixes 50/50 with distilled water for year-round freeze and boil-over protection, and the anti-foaming properties help the cooling system maintain consistent pressure and heat transfer.

Because this is a concentrate rather than a pre-mixed formula, you control the ratio and can adjust for your climate. Always use distilled or deionized water when mixing to avoid mineral deposits in the system.
