ABSTRACT:
Herein disclosed is an improved passenger room heating system for use with a boiling liquid type engine cooling system. A coolant inlet tube of the heater core of the passenger room heater is connected to the coolant jacket of the engine through parallelly arranged two coolant outlet ports which are formed in the engine proper. One of the outlet ports is positioned above the other when the engine is properly mounted in a vehicle. A thermally operable valve is associated with the junction portion of the two outlet ports so that when the temperature of the coolant is higher than a predetermined degree, the upper outlet port is closed and the lower outlet port is opened, while, when the temperature of the coolant is lower than the predetermined degree, the upper outlet port is opened and the lower outlet port is closed.
