Pete,
The factory temp gauge sender has caused a number of issues. The range indicated is really not useful or a good indication of actual engine temp and you can damage an engine thinking that you have been a safe zone. Go to the following information:
http://gmcmotorhome.info/engine.html#sender
If you are running the stock radiator you should be running a 9# cap and they are still available and never more than a 10# cap. You can damage the radiator by using any higher pressure rated cap. The aluminum radiators typically use a 14-16# rated cap because they are built differently and do not expand and contract like the stock one would with a higher rated cap.
