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

Replaced the radiator on the car. Used to add coolant. It was nice. This tool created a vacuum in the coolant system and then held it for 10 minutes to ensure there were no leaks. Then just let the coolant system pull the antifreeze through the tool. Filled up immediately. I started the car and as soon as the thermostat opened I waited for the coolant level to drop. He didn't fall. There is no air in the system. What a time saver. Highly recommended. The only problem is that the fitting is a non-standard size for connecting the compressed air line. I had to install standard fittings.
