Frigutec® BS concentrate must be diluted with water before use! We recommend a mixing ratio of 1:1 in volume with demineralised or distilled water. Under no circumstances should Frigutec® BS be used with less than 33 vol.% or more than 60 vol.%.

Miscibility with other engine coolants

Frigutec® BS concentrate only works optimally if you empty the entire cooling system, rinse it and fill it completely with Frigutec® BS mixed with distilled water in a 1:1 ratio.

In principle, Frigutec® BS can be mixed with all commercial engine coolant agents based on 1,2-ethanediol (MEG) with organic additives. However, each manufacturer has found and tested a specially optimised composition of inhibitors which, when mixed with other radiator antifreeze agents from other manufacturers, still work well, but no longer as optimally as Frigutec® BS alone.

In the event of a warranty claim, it is often impossible to assign the cause that triggered the warranty if several different makes have been used.

Therefore, we recommend the use of Frigutec® BS only.
