Still bubbling out overflow after changing water pump, thermostat, radiator,hoses??

You guys are getting 2 cooling systems crossed up.
One is the regular or standard cooling system, the second is a"closed cooling system".
Do not get the two confused. Our older cars ran a standard cooling system, while newer cars run a closed system. You can Google the differences between the two.
After looking in my Factory Service manual, something everyone should have, or something close, the standard cooling system should have the coolant, 1 1/4" below the filler neck when the car is cold.
