COOLANTS

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. Specially formulated with advanced additive technology, this product provides extended service maintenance protection in heavy duty applications without the addition of SCAs, and meets nitrite-free coolant requirements of many industry-leading OEMs.

Advantages:

  • Extended service life of 1,000,000 miles or 20,000 hours*
  • Free of phosphates, silicate, nitrites, amines, and borates
  • Offers excellent wet sleeve liner cavitation protection
  • Contains better heat transfer properties than conventional coolants requiring SCAs
  • Eliminates maintenance with no SCAs required
  • Provides freeze and boil-over protection
  • Extended life 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 coolant technologies including conventional and Organic Acid Technology (OAT)
*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.
