Repair g5 LCS

[OliverOSX93]

Okay. I recently got a G5 with a fried power supply (caused by leaking LCS) and to my surprise the CPU was pretty much untouched! (just a little contaminate on the tops of 3 of those little capacitor thingies. (not entirely sure what they do, but I'm 95% sure nothing bridged)

Will I need to replace the tubing on it (It seems to have leaked out the O-ring) and what coolant shall I use as a replacement? I already have some Arctic silver 5 for when I rebuild everything and I've got some alcohol in the post.

Finally, How do I actually drain the unit and refill it?

for a temporary solution on my g5 i just sealed the watercooling blocks back up with silicone and refilled the lcs with water and it is working well. Oh and my cpu cards where in quite a mess (http://www.flickr.com/photos/74509210@N04/sets/72157628902508561/with/6710800305/). and make sure you get the cpu cards in the same way round, or your fans will run at 100% all the time (and asd wouldn't run thermal calibration on my g5)

You've just given me hope of this working!

Any idea on how to remove a partially stripped screw? It's the one connecting the power supply to it's cover.

well i had that a few times (was the screws holding the cpu cards to the watercooling blocks in my case tho), i just took a dremal and cut a slot into the top of them and unscrewed them with a flat blade screwdriver

2 Problems >.<

Okay I've run in to a couple problems.

1) I can't find O-rings that are the correct thickness. Can anyone please link me to an online retailer?

2) I broke one of the screws that keeps the CPU boards attached to the motherboard (and lost a few others, but I can find those). Will it be okay with without every single screw? If not can you link me to some online please?

Thanks for your help

Search this forum for "O-rings", there are several posts of people who have extras and offers to supply others in need.

Can anyone with o-rings for the 2.7GHz message me please, I don't want to go PMing random people.

And any help on those screws? Are they a standard size or proprietary?

Thanks again for all the help!

if you can post a pic of the screw with dimensions, I'll probably have what you need. I'm assuming the majority would be the same as a 2.5.. shame you don't have a 2.5, I also have o rings. as for coolant, standard computer liquid coolant your local pc repair shop sells is fine.

its the one that holds the psu to the metal plate right? those are the same size as a normal hdd screw, a hdd screw will stick out a bit but they work fine (i lost one of them and just used a normal hdd screw)
