The air lift pulls the vacuum at the reservoir. It lets the coolant back into the system the same way. Remember that there is a over flow vent under the reservoir that you have to plug while doing this. I highly recommend this for filling any cooling system. I even used it to fill the SC cooling systemI assume you are pulling your vacuum via the reservoir, where do you pull the coolant in from? I've probably assumed wrong.
