Corrosion inhibitors le tsona li sireletsa se pholisang ho tsofala pele ho nako. Mohatsela o ka har'a li-radiator tsa koloi o lokela ho fetoloa hangata hakae? Tsohle li ipapisitse le moetsi le li-additives tse sebelisoang ho tsona - tsa khale kapa tsa manyolo.

Lilemo tse peli ho isa ho tse tšeletseng
