Your reservoir usually has a fill line that you fill to…water is non-compressible so you cannot fill it right to the top, or any heat will cause it to pop the pressure relief built into the reservoir cap…

Yup it does see freezing temps.
I will have to wait around 4 weeks for warmer weather and then change all my fluids.
15W50 Oil, Destilled water + water wetter for coolant.
Last year I used 100% destilled water during summer.

I didn't find a fill line.
Callaway instructions say the following:
"fill the reservoir tank completely, replace the cap and turn the vehicle off."

The thing is, as soon as the pump starts, fluid level decreases inside the resevoir because it fills the entire system (top of the supercharger).
Because of the increased flow it splashes into the resevoir which is maybe 1/4 full when the pump runs and creates air bubbles which some of them get probably sucked into the system.
