Ready to use coolants

 

— antifreezes, immediately supplied diluted to the desired proportion. Such liquids are more convenient to use than concentrates: there is no need to bother with dilution, you can fill in the “coolant” directly from the package. On the other hand, ready-made compositions are less frost-resistant — at best, the freezing point in them is -50 °C, and most often it is even higher. At the same time, it also happens (especially in inexpensive brands) that the actual frost resistance turns out to be somewhat worse than the claimed one; in concentrates, such situations are much less common. Therefore, it makes sense to choose ready-made formulations, first of all, if you cannot or fundamentally do not want to mess with the concentrate. Among other things, this option is considered optimal for car services, service stations and other organizations involved in mass repair and maintenance of cars.
