I have two complete Liquid Cooling Units (with two 2.5ghz processor boards each) and both have unfortunately leaked. I can confirm at least one set of processors work (the other won't make the box chime but I'm not surprised as those processors came from another G5) and I want to rebiuld one LCU.
I already drained and flushed chean the system and ordered new hoses however I don't know waht to replace the O-rings with. Since they are the source of the leak they have to be a bit larger but I don't have the slightest idea where I would be able to find such replacements and Apple certainly won't do the work for me now (and they wouldn't anyways since I bought the G5 at a recycler for $20).
Does anyone know of any suitable replacement O-rings?
Also, what ratio of coolant (would car radiator coolant be too corrosive to aluminum?) to water would work or what should I substitute the original coolant with? I don't know what happened to the coolant Apple filled one of the LCUs with but something was seriously wrong in the loop.
