Review on 🔧 Improved OEMTOOLS 24444 Cooling System Refiller for Efficient Cooling System Maintenance by Matthew Watkins

I bought this as a tool to avoid borrowing from the other guys in the store and it has some features that are better than many other options . But out of the box it just didn't work, didn't create a vacuum. It's kind of the simplest; Compressed air flows through the tool in the form of a vortex, creating a vacuum. The problem with this device was the connection between the vacuum device and the tank fitting; It had a quick connection to the inner seal, and the inner seal is somehow misconfigured. The tool didn't work at all, didn't create any vacuum until I disassembled the quick connector and sort of pulled its guts out. After that everything works fine. After that, it's a well-made tool. The adapters are pretty versatile and fit most of the applications I need them for, the check valves are well made, the main fitting is solid and looks very solid. A very good and useful tool for the price.
