I am losing coolant and have lack of heat and erratic temp gauge

I have a ford bronco and replaced Radiator waterpump and thermostate and still have no heat and temp gauge goes up and down to hot and then back to cold and coolant loss

Head gasket or cracked head (even more remotely cracked cylinder)... if the coolant isn't going on the ground... its going out the exhaust.
