Finally got it squared away! It was air in the lines, I used the wrong bleeder in billmans instructions, re did the steps using the bleeder by the throttle body and no more over heating!

If you had to remove the radiator cap and add coolant while there was coolant in your reservoir, you were sucking in air at your leak when your engine was cooling down. And since there was a pocket of air in your radiator, your temps would rise during idle. That's because the air was reducing the radiator's ability to extract heat from the coolant.

You should never have to remove the radiator cap unless you're sucking in air.

Makes perfect sense. And yea I wasn't really sure how the system was sucking in air from such a small leak, but it for sure was. All good now!

Fml. So after all this work, and getting the leak stopped, I make it a couple days and today as I'm driving home everything is fine, heater works quick and hot, no over heating. Which means the thermostat WAS working. No problems on the 40 minute drive home, in a little traffic as well, and then a few minutes before I get home, I look down and the same old story. Over heating. I stop and pop the good, feel the bottom hose and it's cold. Obviously the thermostat is to blame. I just don't get how it goes from working fine WHILE driving, and then just shuts itself? Guess I'm ordering a new thermostat

Thermostat can fail in many different ways, perhaps it is not fully opening?

Just a though.

Either way after any overheat it is good insurance to replace the thermostat as a piece of mind.
