How do I remove this spring/compression element on my rad trap?

Jay4334

It appears to be permanently attached, but I am not 100% sure. I have the replacement cage and need to replace this trap ASAP, it's 10 degrees so I need to keep the system running. With the trap off (even with a cork in the return line) the lack of pressure keeps the system cycling every few minutes. (At least I think that's the reason) also I want to avoid damaging any parts that I don't need to. Please help.

They should spin out with a wrench. Just be careful not to break the thread.

Or

grab the old bellows with a pair of pliers. It screws into the top cap and should come right out.

Needed some heat and elbow grease...not to mention patience. Thanks...2 down 8 more to go.
