[. . . ] If the antifreeze mixture is effective to -35 (-37), the boiling point of the coolant in the pressurized cooling system is reached at approximately 266 (130). The coolant solution must be used year round to provide the necessary corrosion protection and increase boil-over protection. Coolant system design and coolant used determine the replacement interval. The replacement interval published in the Maintenance Booklet is only applicable if MB 325. 0 Anticorrosion/Antifreeze solution or other Mercedes-Benz approved products of equal specification are used to renew the coolant concentration or bring it back up to the proper level.
