Castrol Radicool SF is a long-life coolant based on Organic Acid Technology (OAT) chemistry — the 'SF' designation indicating Silicate-Free with G12+-class positioning. The product provides frost protection and corrosion protection of aluminium and cast-iron engine components, with extended service intervals compared to conventional silicate or hybrid coolants.
The product is positioned for commercial vehicle, automotive and industrial cooling-system service where long-life OAT coolant is specified.
Approvals and performance levels include MAN M324 SNF (commercial vehicle long-life coolant); Deutz DQC CB-14 (Deutz engine coolant); VW TL 774F (G12+); and Ford WSS-M97B4 (verify the specific Ford reference against the current product label). The product also meets BS 6580:2010; ASTM D3306; ASTM D4985; ASTM D6210; ASTM D1120; ASTM D1123; ASTM D1287; ASTM D1121; and ASTM D3321.
Castrol Radicool SF is supplied as a concentrate and is mixed with water at the dilution ratio specified by the engine manufacturer.
Castrol Radicool NF is an antifreeze concentrate formulated using monoethylene glycol and selected additives, free from nitrite, amine and phosphate inhibitors. It uses hybrid technology for the modern performance engines of cars and trucks. This coolant should be used at concentrations of between 33 % and 50% dilution with purified water to give optimum corrosion protection and freezing protection between -18°C and -36°C.

A. Castrol Radicool SF is for commercial vehicle, automotive and industrial cooling-system service where long-life OAT (Organic Acid Technology) coolant is specified — typically modern diesel engines and Volkswagen-group vehicles requiring G12+ approval.
A. The 'SF' designation indicates Silicate-Free chemistry.
A. Castrol Radicool SF is positioned as a G12+-class long-life OAT coolant — meeting VW TL 774F, the G12+ specification.
A. An OEM Specification is the coolant requirement set by a vehicle or equipment manufacturer (e.g., MB 325.3, VW TL 774-D / G12+). When a coolant lists the code, the coolant manufacturer has developed and tested it to meet the criteria the equipment manufacturer requires. Match the code in your handbook and you have a coolant engineered for your machine.
A. An OEM Approval means the coolant has been formally tested and signed off by the equipment manufacturer and listed on their official approved-products register (e.g., MB-Approval 325.3). An Approval confirms the coolant is recognised by the equipment manufacturer for service use in their machines.
A. Castrol Radicool SF carries MAN M324 SNF; Deutz DQC CB-14; VW TL 774F (G12+); and a Ford specification (verify the specific Ford reference against the current product label).
A. OAT (Organic Acid Technology) coolants use organic-acid carboxylate corrosion inhibitors rather than traditional silicate, phosphate or borate inhibitors. OAT coolants typically offer extended service intervals — up to 5 years or 250,000 km in many applications — compared to conventional coolants.
A. Both are Castrol Radicool antifreeze coolant concentrates. Radicool NF is the G11-class silicate hybrid coolant for general service. Radicool SF (this product) is the G12+-class silicate-free OAT long-life coolant for extended-service-interval commercial vehicle and modern engine applications.
A. BS 6580 (UK) and ASTM D3306 (US) are the universal coolant performance standards every reputable coolant meets. They are your baseline check — match the standard your handbook specifies and the coolant is technically suitable for your system. Every coolant on our site lists its BS 6580 and ASTM D3306 classifications.
