Review on 🔧 Improved DAYUAN 28-Piece Universal Radiator Pressure Tester & Vacuum Cooling System Kit by Jason Melvin

I bought this because I needed it. I had to pressurize the system and will be using a brand new gauge and #1 only has a metric nipple and I don't have a quick coupler. now i have to buy it. #2 I'm looking at the device and the person who glued this thing together didn't care how they did it. It's wrong. I plug in my supply air to exhaust the cooling system. Everything is fine, all hoses are flattened. After 5 minutes I stick the supplied small end hose into a bucket of coolant and I'm ready to draw liquid. It starts and stops. To draw. What the hell? after canceling and repressurizing. here the screen is so good that it does not let any coolant through. God, take that thing off and start over. On the other hand, it seems good for the money now that I know how to use it!
