Coolant Vacuum Fill

[timc930]

Bought the OEM tools coolant refill 24444. How much vacuum should I pull before I fill, and do I need to keep the compressor air going to keep a constant vacuum?

I used around -20psi to fill.

Mine went to about -25. Then close the valve and shut off the compressor. Let it sit for a minute and make sure you don't have leaks. Then open up the fluid fill.
