Coolant Pressure Bottle

This bottle keeps coolant free of trapped air. It provides a volume for expansion and contraction and provides a convenient and safe method for checking coolant level and adjusting level at atmospheric pressure. It also provides some reserve coolant to cover minor leaks and evaporation or boiling losses. See Fig 1 and Fig 2 .
