Review on 🌬️ UView Airlift Cooling Checker 550000 by Richard Cunningham

I hadn't even heard of one like this a few weeks ago. I had to flush my RV's cooling system, it holds almost 11 gallons of coolant. I had no idea how to get all the bubbles out of such a huge system, but after reading about this thing I decided to give it a try. I was not disappointed. With my compressor I was able to create a vacuum in the system, but I could only increase the vacuum to 22-25 on the gauge. I ended up letting coolant into the system three times, each time pulling a new vacuum with the liquid already in the system. In my case it worked fine, very little liquid came out when creating a vacuum in the coolant system. Overall I'm very satisfied, I'm sure my friends will be happy to use it if needed.
