Using the calibrated beaker, I added 450ml more water - -



which brought the level to about 5mm lower than the top of the fins.

Clearly, this apparent increase in the volume of your coolant isn't due to variations in ambient temperature/pressure from one inspection to the next.

I suggest you have a carbon dioxide test done on your coolant. Either a garage can do it or you can buy simple DIY test kits on eBay.
