This isn't a problem anymore for me, but I wanted to share my experience installing the coolant self-bleeder and allow you folks to try and make sense of it. After I correctly installed the self-bleeder, I ran my car for awhile, and after 20 minutes I noticed a few things. The first being that the temperature was 220 degrees, and the fans still had not kicked on. The other is that my stainless header bottle was cool to the touch. This I thought was very strange. I shut it off in fear of overheating. Immediately I went back to the engine compartment, observing my header bottle was cool to the touch, so I twisted it open. No coolant splashed out at me, but rather I heard a few seconds of "gurgling" noises. With that, I screwed the cap back on and came back to the car a few hours later. I started it and let it run, and this time my coolant bottle heated up normally, and my fans kicked on between 160 and 220 as usual. I have not had the original problem since. So what the heck just happened here? It seemed as though the coolant had "stopped up" in the engine, but after I opened the header bottle cap, it somehow opened back up again.
