Hi Anthony, funny you should say that, my cap looked perfectly OK but was also 22 years old. When I refilled there was alot of air to get out, I now need to get some anti freeze in there but the only way I seemed to get the air out was by blowing the hose pipe down the heater pipe so not sure how I'm going to get the air out when I have added the antifreeze..Martin

ah, You could try my amateur unpatented not sure it works but is fun method but there's loads on here about how to get the air out, not least filling from the highest point of the system and/or using an air bleed thing fitted near the heater. Anthony
