Assuming you compress the vapor pressure and close up the molecular bond/spacing with these crazy pressures.

30 PSI & a 10 year old expansion tank = red temp gauge.

Be curious to check the 10 year old expansion tank cap that has never likely opened to see if the cap is even any good?

I hear that there is a 1 Bar replacement for the newer BMW's that most parts departments hand out, be curious what the part number is?
