Castrol Antifreeze NF

PRODUCT DESCRIPTION
Castrol Antifreeze NF is a superior, Heavy Duty Diesel engine coolant, formulated to provide
excellent corrosion protection for modern engine alloys found in radiators, water pumps and
cylinder blocks & heads. Castrol Antifreeze NF is a nitrite, phosphate and amine free, fully
formulated glycol coolant and has been designed to meet the requirements of the major European
OEMs. Castrol Antifreeze NF provides an effective heat transfer medium, withstanding the high
temperatures found in modern cooling systems, while also providing antifreeze protection to
temperatures of -38'
C. Castrol Antifreeze NF uses hybrid technology, a combination of organic
and Inorganic inhibitors, which increases the service life beyond that of conventional coolants.
Mixing different coolant formulations is not recommended, as this may cause precipitation of
inhibitor components and could result in over heating and reduced corrosion protection.

PRODUCT APPLICATION
Castrol Antifreeze NF has been designed to meet and generally exceed the specification
requirements of most major European OEMs and is particularly recommended for use in heavyduty
European vehicles. Castrol Antifreeze NF is suitable for engines of both ferrous and
aluminium alloy construction and can be used in the cooling systems of cars, light or heavy
commercial vehicles, tractors and off-road applications where a high quality Nitrite free coolant is
called for. Castrol Antifreeze NF is a fully formulated, ethylene glycol coolant concentrate. The
concentration of the engine coolant used should be that recommended by the vehicle
manufacturer. In the absence of such guidelines, Castrol Antifreeze NF should be diluted with
good quality water in the concentration range of 30 - 50% v/v. NOTE: If Castrol Antifreeze NF is
to be used in conjunction with an SCA, maintain levels as per engine operators manual. Contact
the Castrol Technical Department for information regarding compatibility with SCA's.
