General
To provide for changes in volume in the closed jacket water cooling system caused by changes in temperature
or leakage, an expansion tank must be installed.
As the expansion tank also should provide a certain suction head for the fresh water pump to prevent cavita-
tion, the lowest water level in the tank should be minimum 8-10 m above the centerline of the crankshaft.
The venting pipe must be connected to the expansion tank below the minimum water level; this prevents oxy-
dation of the cooling water caused by "splashing" from the venting pipe. The expansion tank should be equip-
ped with venting pipe and flange for filling of water and inhibitors.
