Cooling Issue - 1964 Dart GT - 273 with automatic and A/C

Hi,

I would guess that you have an air pocket in the system.

Take a 2 liter bottle. Cut off the bottom. Wrap the screw opening with some tape. Remove the rad cap. Screw in the 2 liter bottle. Fill it up with some coolant. Fire the car and let it operate. Once the bubbles stop and it looks like coolant was used and your satisfied stop the motor. Carefully, remove the 2 liter and remaining contents. They sell kits to do this, but this is cheaper.

FYI,
