Review on 🌬️ UView Airlift Cooling Checker 550000 by Michael Boyle

Used to fill the cooling system on a 2015 Prius V engine after replacing the head gasket. Works as described, no problems. As previously mentioned, you will need to purchase a threaded fitting to connect the air hose. For me I bought a 1/4 inch connector for about $3. I was able to get to 25 with just a small 2 gallon 125 psi hot dog compressor. First hauler went to 20, then I had the tank refilled and went back to 25. Couldn't get to 30 but still filled the entire system to 25. Note that out of 1.8 gallons of coolant only the Prius uses it about 1.4 gallons comes out of the radiator drain plug. So if you plan on flushing and then topping up you will need concentrated coolant to get a true 50/50 ratio as there will still be some water inside. I've heard there's another drain plug on the engine block to drain more, but I never paid attention.
