Abstract
A filling aid for field filling the engine cooling system of automotive vehicles with cooling liquids. For field service, the filling aid is mounted in a stabilized upright orientation by an integral fluid sealing connection to a filler neck of the deareation chamber of a coolant bottle of the system so that it extends above the bottle. Coolant is added into the cooling system through the filling aid until the filling aid and deareation chamber are filled with coolant. Because a taller column of coolant has been established by use of the filling aid, potential energy is increased and coolant is quickly fed by increased pressure and force into the engine cooling system. When sufficient coolant fills the system, any coolant left in the filling aid may be released by removing a closure clamp previously installed on an overflow tube leading from the deareation chamber so that it drains with no spills from the filling aid to an overflow chamber of the coolant bottle.
