I still dont really understand what is happening.
I let all the coolant out of the system by opening the bolt with the butterfly wings on the radiator. After that I can only fill just about 3 gallons of new coolant.
What am I missing because it should be 17 to 18 quarts? I used a vacuum on it and still the same... Put it on an angle because of air buble but still the same.
engine temp is also at normal operating temp when I let it warm up. Thermostat also works normal.
