And of course you need a very large bucket/bowl/baby bath in the trunk with more than enough coolant for the entire refill.
Yes, you can use the valve to stop and start but unless you are quick and careful you will get a slug of air entrained in the suction hose.
There may be a better way?
There is. While we use the Uview system, we added an extra shut off valve on the coolant pickup line, which allows you to "pre fill" the line before actually starting to pull coolant in. This eliminates any air entering the system, and also allows you to stop the process at any time, like to add more coolant and distilled water to the 5 gal pail we use to hold the mix.
