I found a bunch of "Airlift style" vacuum coolant fill systems under $80 on ebay.
I don't really understand how they work.
Do you attach a hose at the system low point to suck in the coolant and then apply vacuum at the coolant tank? Where is this low point?
From one video I saw it looks like you create a vacuum at the overflow tank and then let it suck fluid back into the system from the tank fitting.
Doesn't make sense that all bubbles get eliminated that way as its the same as just pouring in fluid from the tank ?
Can someone elaborate?
