I've got an eBay radiator and it doesn't have a proper air bleed valve to fit a clear plastic tubing. There's an opening for bleeding air but it's just a simple screw type plug like the drain cock, so bleeding air is a bit crude but doable, certainly not pleasurable 
Is there an air bleed valve attachment I can buy that requires little or no modification or would this involve some custom job to the radiator?
Cheers

Please do not use "cock" and "pleasurable" in the same sentence again LOL 

Photo, I'm curious if this is anything like the PWR set up?

Please do not post pics of the bleeding cock.

The air bleed screw plug is on the right side near the stamped letters
