Andrew Smith : Depending on the age of your radiators, is there a 1/2" plug you can crack open that the air vent is part of?
JACUSTOMER-nz8czmij- :

i dont know what the 1/2 inch plug is???? The radiators are about 20yrs old fairly thick metal. Can a new vent be fitted as they stand. Present vent is on the inside close to wall.

Andrew Smith : If the vent is on the back side close to the wall then no you cannot unscrew them.
Andrew Smith : the only option is to drain the system, remove the rads and fit new air vents.
Andrew Smith : you may have to use a hacksaw to cut a groove in the old ones and use a screwdriver
