Thanks d. I got a screw sealed onto the radiator and it seems to be working fine. If something goes wrong I'll ask them to try one of your suggestions. I appreciate your response, thanks again.

why dont you try to replace it with a bicycle tyre valve,or a brake caliper bleed nipple, both will release trapped air.
