Review on 🌡️ PBT 70888 Cooling System Master Test Kit by Daniel Evans

This only works with an open cooling system! I've followed the instructions exactly and I can't get it to work on open cooling systems. It's not mentioned anywhere, but after researching how it works, I came up with it. In addition, the list of compatible vehicles uses an open system, which does not have vehicles with a closed system. I like the idea, but poorly implemented.
