So, it dawned on me that if there were a way to relieve the pressure without risking any spray-out, it just might help the new one last a little longer than 3 months!
My answer? I broke out the drill (always a good start

The results? Unbelievable. Over three years on and it looks like new. No kidding! I can't believe it, either. I have experienced absolutely no cooling problems whatsoever (live in LA, where it's routinely 90+), and no drips, or leaks at all.
It's worth a try, before you spend a chunk of $$ on a metal one.
I can take pics, if anyone wants to see what I did.
