ABSTRACT:
The coolant outlet housing of an engine contains a horizontally movable type thermostat and an air vent bypass passage located in the housing at a point above the thermostat to assure the bleed of air from the coolant to the radiator during the filling procedure, the passage containing a one-way ball check valve to permit the bleed of air but prevent the passage of coolant past a closed thermostat to the radiator.
