16 Section 3 Cooling System
* If a single fill/vent line between the expansion tank and the engine cannot be used, separate lines must be used for filling and venting the
tank. A 1/4 in. (6 mm) vent line is routed from the engine top tank to the expansion tank. The expansion tank fill line goes from the bottom of
the expansion tank to the top of the keel cooler return line. A separate line, dedicated to filling the system, must be sized to meet the fill rate
requirements published by the engine manufacturer.
