Review on M31 Vacuum Purge Coolant Refill by Joseph Ramos

I was in the process of replacing the water pump on my 987th generation Boxster. I couldn't rent this instrument or borrow it from friends. I dared and I'm glad I did. The price is amazing for the metal construction and nice box to keep everything organized. I like to have 3 sockets depending on the car, the small socket worked fine on my Boxster. The tool is very easy to use and sits very securely on the spatula next to it. The vacuum gauge can be easily rotated. The tool was able to pull the vacuum very quickly and on the closed setting it held the vacuum for a while, great confirmation that replaced hoses etc weren't leaking. The filling tube has a strainer and a one-way valve. All in all, it filled my Porsche Boxster cooling system with no problems.
