Thermostat housing had broken in the side the lower radiator hose goes into. It had popped out and all the coolant had drained out. Replaced the thermostat housing and filled up the coolant. Turned the vehicle on and blasted the heat. The coolant filled to the top and starting bubbling. At one time it was spilling over and then after a minute the coolant went down. Now, filled the reservoir with coolant up to the fill line. How much more coolant should I add to the system? It's not filled to the top, but I already used 2 gallons of coolant between the reservoir and the system. Is the car safe to use? The heat is on again and the temperature is in the center between hot and cold like it should be.
