No problem.  It was a good opportunity to reiterate that point, as I feel having the thermostat housing well elevated above the radiator cap opening during the burping procedure to be critical. It allows pockets of air to naturally gravitate towards the rear of the car, and hopefully end up at the thermostat housing where they can be released into the atmosphere.[This message has been edited by Patrick (edited 06-15-2022).]

Yes, that's how I do (did) it too.
Anyway, I checked the levels in the overflow bottle with a cold and hot engine. There was no difference.

Well, something's definitely funky.  The coolant level in your reservoir should be going up and down during every heat cycle of your engine... but you already know that. I can't help but think that this is indeed related to the wild temperature fluctuations.[This message has been edited by Patrick (edited 06-15-2022).]

I guess my only question is in the morning when cold and you start the car, do you smell antifreeze from the exhaust?

...and/or is the crankcase oil starting to resemble a milkshake?

Instead of removing either cap, especially the radiator cap, you should be able to determine coolant level by simply looking at the level in the reservoir. It should be at the lower mark when the engine is cold, and at the higher mark when the engine is at operating temperature. The reservoir should never be empty, and/or never be boiling out of the top.

Um...oh. Huh. I rarely have any liquid in there. Temps have almost always been fine, except when I had a heater core leak, and the fluid levels were down. Added more fluid and off we went.

I've got one question for you.

Well, I guess I'll make sure there is, going forward

I need to consider it's just an erratic temperature sending unit...
Yesterday, after having driven the car, I wiggled the wires from the temp sender a bit, just to see if it felt loose. It didn't. But then today, my temperature gauge wasn't reading anything at all. So I stopped the car and started wiggling the wires again and the temp gauge came back to live.
