Eufreeze -40°C Ready-to-Use Coolant Antifreeze - COD REUPR-331
The Eufreeze -40°C ready-to-use protective antifreeze and engine coolant (package references PR001-331 and PR020-331 - product line COD. REUPR-331) is an advanced technical fluid formulated from high-purity monoethylene glycol (MEG), engineered to deliver outstanding cooling performance and thermal protection across petrol, diesel, and hybrid internal combustion engines. Designed for direct application without water dilution, it provides dependable sub-zero freezing protection down to -40°C along with superior boiling prevention and heat dissipation under severe driving loads. Its specialized chemical formulation is strictly free from Nitrites, Amines, and Phosphates (NAP Free), preventing galvanic corrosion, water pump cavitation, and harmful scale or sludge deposition throughout radiator passages. Complying with extensive international standards and leading OEM specifications including CUNA NC 956-16, ASTM D 3306, Mercedes DBL 7700, VW TL-774 C, Iveco, Fiat, MAN, and BMW, it safeguards cast iron engine blocks, aluminum cylinder heads, copper cores, and elastomer sealing components.
Key Features and Construction Advantages
- Ready-to-Use -40°C Formula: Factory pre-mixed with high-purity demineralized water for immediate filling, eliminating field dilution errors and water-borne scale buildup.
- Eco-Responsible NAP-Free Chemistry: Formulated without nitrites, amines, or phosphates, minimizing environmental hazard while maintaining long-term chemical inhibitor stability.
- Superior Thermal Exchange Performance: Substantially depresses the freezing threshold while elevating the boiling point, preventing coolant boil-over and engine overheating in heavy duty cycles.
- Active Anti-Corrosion & Scale Defense: Shields all internal cooling passages from rust, oxidation, and mineral encrustation, protecting water pumps, thermostats, and radiator channels.
- Total Rubber and Plastic Compatibility: Chemically neutral toward EPDM hoses, silicone gaskets, and plastic cooling headers, preventing seal hardening, shrinkage, and leaks.

Operating Guidelines and Workshop Notes: This coolant is strictly ready-to-use and must be poured directly into the expansion tank or radiator as supplied; do not dilute with water, as adding water will diminish corrosion reserves and reduce the -40°C freeze protection. Prior to a full refill, drain and thoroughly flush the cooling circuit with clean water to remove exhausted fluid residues and loose scale deposits. Never open the cooling system cap while the engine is hot or pressurized to avoid severe scalding hazards. Periodically verify fluid levels when cold, ensuring the coolant line rests squarely between the minimum and maximum reservoir markers. Store bottles and jerrycans tightly closed in their original packaging, kept away from direct sunlight, children, and pets.
