Coolants/Anti-freeze
Our coolant range offers excellent protection in commercial vehicle engines and features extended life products that maintain performance even under extreme conditions.
As commercial vehicle engines – especially those running on natural gas – run hotter than before, engine cooling systems need to work harder. Materials that make up cooling systems vary from vehicle to vehicle, so it is vital to make sure that you use the right coolant for each application.
Our coolant range offers excellent protection in commercial vehicle engines and features extended-life products that maintain performance even under extreme conditions.
Castrol® Radicool ™ SF-O premix
Castrol Radicool SF-O Premix, a heavy-duty, nitrite-free, extended-life antifreeze/coolant, is a premium quality, Organic Acid Technology (OAT), ethylene glycol-based fluid.

*HD Extender may be needed based on water quality.
Castrol® Radicool™ Heavy Duty Premix
Castrol Radicool Heavy Duty Premix is a premium quality, conventional technology ethylene glycol-based fluid. The product is specially formulated with industry-leading additives to provide optimum performance in heavy duty vehicles requiring supplemental coolant additives (SCAs).
Advantages:
- Contains nitrites for superior wet sleeve liner cavitation protection
- Provides freeze and boil-over protection
- Designed for heavy duty applications, yet can be used in automotive applications where conventional technology coolants are acceptable
- Phosphate-free with low silicates
- Effective, long-term corrosion protection for steel, solder, copper, iron, brass, and aluminum
- High-quality defoamer system, non-harmful to hoses, plastics, or gaskets
- Compatible with most major American brands of conventional coolants, both with and without the addition of SCAs*
- Appropriate for use in on-road and off-road diesel engines, as well as in stationary engine applications where a conventional pre-charged coolant is required
* SCA levels will need maintaining throughout the life of the engine. Always consult the vehicle owner’s manual for guidance.
