how do i get rid of an air lock in my ford focus?

if the expansion tank is cold then you need to look at changing the thermostat, if you have already done that then you may have a blocked radiator or possible a blocked heater matrix but a bloxed matrix wont cause the expansion tank to be cold most likely the stat or in worst case the radiator.
