Thanks, yah that's good that you an confirm that. It's been working correctly the past couple days now. I've been keeping an eye on it. I guess the jury is still out but perhaps it was air bubbles. I'll report any new info as it comes.Can't contribute much to the conversation here, but I have done the throttle body coolant bypass, and can report no changes whatsoever to my coolant temp readings. I haven't even replaced the ounce or two of coolant that was lost rearranging the hoses.
