Gilera 633721 - Braking System

DO NOT EXCEED THE MAX. LEVEL WHEN FILLING SO AS TO AVOID THE COOLANT ESCAPING
FROM THE EXPANSION TANK WHEN THE vehicle IS IN USE.
N.B.
THE COOLANT CONSISTS OF A MIXTURE OF DE-IONISED WATER AND FLUID FOR SEALED
CIRCUITS. THE MIXTURE THUS OBTAINED LOWERS THE FREEZING POINT OF THE COOLANT
TO - 40°C. THE MIXTURE IN COMBINATION WITH THE PRESSURE OF 0.9 BAR RAISES THE
BOILING POINT TO APPROX. 125°C. THE RECOMMENDED LIQUID ALSO PROVIDES PROTEC-
TIVE FUNCTIONS FOR THE ALUMINIUM ALLOYS. THIS CHARACTERISTIC MAY DECREASE
OVER THE COURSE OF TIME; THIS IS WHY A PERIODIC REPLACEMENT OF THE COOLANT IS
INDISPENSABLE.
N.B.
FOR THE REPLACEMENT OF THE COOLANT AND THE FLUSHING OF THE SYSTEM, SEE
CHAPTER COOLING SYSTEM.
