Out side temp is about 60 degrees - Radiator water temp 170 degrees. The water level is down about 2 1/2 inches before it stops dribbling out. At this point I,m totally confused. It doesn't have an overflow tank. The only pressurized cap I can find for a 1940 120 is for the Clipper model. Gentlemen I thank you for your help. Perhaps things will change when the weather warms up, but for now I'll keep 2 gallons of water in the trunk. Head gasket is OK - no water in oil or oil in water. One eye on the road and the other on the temp gauge. Thanks for the responses
