OIL COOLER DE-AERATION LINE
A de-aeration line is used to vent air which may
otherwise become trapped in the plate-type oil
cooler when filling the cooling system with
coolant. On ASET™ AC engines the line is routed
from the top of the oil cooler to a port on the side
of the water manifold, just to the rear of the
thermostat housing. The de-aeration line is made
from 1/4-inch inside diameter (1/2-inch outside
diameter) silicone heater hose, and is protected
from rubbing and chafing by a length of
convoluted tubing.
