ABSTRACT:
A reservoir has an electrical heating element therein connectable to a power line and the reservoir is connected in series with a coolant carrying hose which in turn is connected to the coolant system of an automobile engine or the like. The reservoir is provided with an inlet connection and an outlet connection both situated adjacent the upper side of the reservoir. The inlet connection has a one-way valve allowing coolant in only, and includes a ball which has a specific gravity less than the specific gravity of the coolant so that the ball floats in the coolant and closes off the inlet connection when the coolant level is adjacent the upper side of the reservoir. The outlet connection has a one-way valve allowing coolant out only and includes a ball which has a specific gravity greater than the specific gravity of the coolant so that the ball normally engages the valve seat and is only displaced if and when the pressure of the coolant and/or the air in the air space above the coolant level increases. When the coolant level drops due to the expulsion of some of the coolant through the outlet, coolant flows into the reservoir through the inlet connection and the coolant reduces the temperature of the coolant within the reservoir thus allowing more coolant to be drawn into the inlet valve until the level rises whereupon the inlet valve closes and the cycle is repeated.
