Interesting stuff...but how do I know if there is air in my system and if that air is actually causing a problem? I have a '94 with an open system. I have always thought that, because the overflow bottle is not airtight, that was the "vent" for excess air or air that results from minor boiling of fluid from hotspots.
If you fill an overflow bottle when the engine is cold it will throw it out as soon as it becomes hot, the overflow bottle should be at minimum when cold and at max when hot. You can add fluid to reach the full level only WHEN THE ENGINE IS HOT.

This is all really interesting stuff to me. I think my problem is just an old clogged radiator. Even though it has been flushed I think to much gunk has built up over time. I am going to install a new radiator this weekend and hopefully this will solve my problem, heck it can't hurt at all. So here is my next question....Where and what radiator should I buy? Nothing crazy expensive, just a solid replacement. Thanks in advance!
I have done it.
I unwelded one of the headers and used a wiper blade rod to push the crap through the tubes. 80% were clogged. You can't even imagine what came out: mud, leafs, dead bugs, a penny etc.
I enjoyed doing this. My radiator is 22 years old and it never overheated again after i did this.

If you have the old style rad with the brass headers it can be serviced.
