Yes - 4.0. The heater core hoses do run at valve cover level, higher than the radiator. I like your idea of modifying one of the heater core hoses, but I am hesitant to splice hoses because in my mind more fittings mean more potential sources of leaks and failures. I'm hoping most/all of the air is out of the system. I filled the heater core with fresh distilled water from the from one supply line which has an L-shaped bend near the thermostat housing. After filling up, I took it for a test drive and the expansion tank dropped a few inches, but still had coolant in it. I have since filled it up to the Full mark.
Does a rising/lowering expansion tank fluid level indicate that air has been purged from the pressurized part of the system?
