If it wasn't before it probably is now. First thing is to check how much water is in the radiator. Should be topped up full. Do this with heater fully open (hot) back & front. Try running it from cold with the rad cap off and check/top up the level if it starts shifting air out. If it overflows straight away then probably head or gasket gone.
