Radiator protection, coolant additive concentrate (Colour: yellow/green)

Customs number: 38200000


  • FREECOOL RND is a full concentrate based on ethylene glycol, coolant and heat transfer agent for summer and winter operations with frost- and corrosion protection abilities (all year round).
    With FREECOOL RND, the silicate-free carboxylate technology enables long-term protection for all applied materials on the engine, especially for aluminum and iron alloys.
    FREECOOL RND offers a long- lasting corrosion protection by the use of optimized organic corrosion inhibitors.
    FREECOOL RND is free of nitrite, amine, phosphate and silicate.

  • Characteristics

    • Longer and outstanding corrosion protection
    • Improved heat transfer
    • Decreased right to compensation regarding repairs at the coolong system
    • Environmentally friendly by the use of carboxylates
    • Avoidance of foaming
    • Compatibility with hose and sealing materials
    • Compatibility with varnishes
    • Improved heat pump performance


  • FREECOOL RND can be used without restrictions in engines out of cast iron, aluminum and/ or a combination out of both metals in cooling systems made out of aluminum or copper alloys.
    FREECOOL RND is particularly recommended for high- tech engines that require special aluminum protection at higher temperatures.
    Typical mixtures in Northern Europe contain 50% of FREECOOL RND and 50% of water at which a frost protection down to -38°C is achieved. Reliable corrosion protection is achieved from 30% of FREECOOL RND and 70% of water.

  • Usable for

    We recommend this product for: 
    DACIA 41-01-001/--T 
    MB 325.7 
    RENAULT 41-01-001/--T 


    • FREECOOL RND is miscible with several coolants based on ethylene glycol. For an optimal corrosion protection and to prevent sludge formation the unmixed use of FREECOOL RND is recommended.
    • For mixtures we recommend the use of deionized (demineralized) or distilled water.
