Works very well
Got this and 5ltr of Mayhems Ultra Pure H2O 5Ltr to service my water cooling loop after a year of use .As i only use clear pre mix coolant in coloured tubing i cant say if its any good with removing deep colours .All you need is in the box but before i started i did watch the utube video on Mayhems channel ,this helped to make the instruction even clearer .It dose foam so take that in to account when using and i flushed out a few times extra just to get it all out but that may be to the way my loop runs .They say your system will run better for it and my loop temp did go down after .
