JFP -Thank you for the suggestion of an additional valve. That is an easy ,inexpensive fix.

if i read JFP right, he meant that option 1 is replacing the whole valve assembly (part 11 in the diagram) Vs replacing only the O-Ring (part 9)
i wouldn't go and replace the whole tank if it is not leaking.
very expensive part, and very hard to replace.

You are correct. More often than not, trying to repair that valve or replace the O-rings comes to grief. So while replacing it may not be the cheapest approach, it is the one with the least chance of coming back to haunt you.

Problem solved!


The large O-ring in the coolant bleeder valve was bad. There is a strange crimp in it that is likely from initial assembly, I don't think it has ever been apart. It is unbelievable that it ever provided a proper seal. The fuzz in the picture is from a rag.

It was a 15 minute, $5 job to remove the valve and replace both O-rings. Now my tank holds pressure and the coolant level only moves from mid-tank to 3/4 tank from cold to hot.

That is one UGLY O ring
