Review on YSTOOL Radiator Pneumatic Universal Automotive: Efficient Cooling Solution for Cars by Rolando Munoz

Well you've got a bunch of adapters to start with, I'll probably never use half of them but if the need ever arises I'll have them. I couldn't take this tool apart but for the price it's a good buy. The chain that the tool hangs on is cheap and falls off, so what... the only thing I've changed on it so far is the quick release on the intake side for fresh coolant. It sucked in air and defeated the purpose of vacuum filling, so I just inserted a barb and pressed the hose against it. Problem solved.
