back into the system from the expansion tank only if the end of the hose is
submerged in coolant, either because it enters the tank from the bottom or
from the top in which case, as Kimo points out, the hose clamps must be tight
so that the vacuum created within the radiator is preserved in order to draw
liquid.</DIV>
