This is on Karla Kat, a 1999 s70 AWD
She is a capital auction special, I drove her home from DC in blissful ignorance like this.
The coolant level bulb is self tested by the DDM on a 1999, so I knew the bulb was good. Silly me for not checking for a bypassed warning system.

Juno is a December 2025 rescue from ARF Hampton’s who talks every morning.

Wrapping up this.
I measured the dead volume of the heater core 9144221 as 300 ml +- 50ml
This does not include any pipe volume. Temperature 22c, P= 1012 torr, Jupiter aligned with Mars.
