Hai Madginsalasa
My experience I cross the check point every day, every time when there is a jam I have to push my berb, Flush the system put in new coolant and replace the radiator cap to a higher rating 1.3, it did reduce/lower the temp but you got to make sure that your coolant hose is in good condition, happen to me it burst in the middle of the jam at the check point spraying hot water, poor guy next to me got hot water spraying to his leg. the principle is that the higher the pressure the lower the boiling point.
