Hello Everybody,


    I've finally decided to give up food to fix the Dual G5. Found  
some CPUs in good working order and received some liquid cooling  
supplies.

I took apart the whole liquid cooling system and found that the water  
blocks were leaking. The seal between the cover and the block had  
failed. This is a known common with many early G5 liquid cooled  
systems. Another known problem is leaking from the pump with a  
diaphragm section underneath the pump to allow for fluid expansion. I  
didn't notice any fluid leaking from that section. I replaced all the  
pipe and braided hose with clear hose and the fluid is now Feser One  
clear/blue coolant. I finished filling the system today and I have it  
on the desk next to me running so I can check for leaks. Later I'll  
attach the CPUs to the blocks and then attempt to mount it all in the  
system and hope everything checks out.
