What is the Cooling System Liquid made of?

Hi againe all,

I want to check the liquid level in the cooling system of my G5/2x2,5 GHz.

Is that possible?

Is it water inside - or a special liquid - what liquid is it, if not water?

Do I need any special tools or another equipment?

Is it possible to check without remove the hole cooling system from the motherboard?

And finnaly - the lewel of liquid

( as I see it it must be some air also - so it can take the expansion related to heat/Higher temp).

IMPORTANT: Following these instructions will probably result in the irreparable damage to your computer. Also, these chemicals will probably kill you in a few days, your home may be declared a superfund site and your family's hair will fall out, if your house doesn't burn down first. Basically, your life is in your own hands. I don't think you should do any of this. ( :

The best information I could find regarding the liquid, is that its green and may be propylene glycol. I found more reliable "looking" information that says its Delphi 151 Coolant Fluid.

Most importantly though, the system is sealed (or is supposed to be) so unless it shows signs of leaking, the level is fine. If there are signs of leaking (which is a problem with some models apparently) then you should stop using the machine and unplug it since it is now a safety hazard.

If it is leaking, you could do a couple things to fix it yourself. Remove the cooling tubes/heat sink to do this...

First, find the leak. You should see some corrosion around that area. Take some steel wool, and clean the area until it is bright and shiny.

Take a very, very small drill bit, about the size of this asterisk (*) and use it to drill the hole out. You are trying to remove any corrosion from the hole and open it up so that the original tube thickness is revealed.

Next, if you think there has been a significant fluid loss, you COULD use water, anti-freeze or the Delphi 151 fluid to fill it back up. Use a syringe to slowly add it, rotate the assembly around so most of the air comes up to the hole, fill some more, repeat. Do leave a little air space, you probably wont be able to help it.

Dry off any fluids that may have dripped and get ready for the fun part.

Once you have the area clean, the corrosion cleaned out of the hole and it filled with the fluid of your choice, get some acid flux and brush the flux around the hole.

Next, get out your super hot soldering iron and SILVER SOLDER. Apply some heat to the area surrounding the hole and fill it in with the solder.

Put it all back together and you are done. I hope it works for you. If this works, you will have saved yourself about $980. If you had to buy the tools, you probably only spent $150.

I agree with not doing this. +

Thanks for this info.

If it is propylene glycol, its no more dangerous than it is in cars, i think.

I am shore that is no leak in my computer.

But IF (only if) the volume level of liquid is to low it mabee can result in "bubbles", and with that less Heat-resistans.

My G5/2,5 GHz is not running well - its "overreacting" when "Original" table of FAN is used (see "Fan speeds up by - mouse or graphic card / G5 2x2,5GHz" -tread - and my solution).

Thats why I want to check the level of liquid.

I think its some explanation behind heat-unstabilyty when the fans jumps "up and down". So this is one of my theories, who has to be precluded or confirmed.

Is some one have other theories, please speak up...

I don't like to give up - and is not to old to learn - the only problem now is to find out if any special equipment its necessary, to open the system.

example - car cooler system its not possible to refill without special adapter, used in the accession.

hi göran, if it's not leaking - let it be. there are other possible ways to get control over the heat issues. did you try a different graphics card from one of your other powermacs (as i mentioned Fan speeds up by - mouse or graphic card / G5 2x2,5GHz ??

maybe you should try a non apple fan system to support the graphics card - use a free slot and put a fan in there - or use a complete fan system for your card, or a few ultra silent fans to cool the card down. many possible ways to get the temperature down ;-)

Hello -

You mentioned wanting to check the fluid level. I do believe there is a reference (I'll get back to you -- need to look through my bookmarks) to the actual cc's of fluid that you should expect to collect - upon opening the system.

I opened one of these bad boys up 2 yrs or so ago upon discovering the beginnings of a leak at the contact site of the heatsink to processors. Frankly, it was a total headache. I suppose it would have been more enjoyable if I hadn't wanted to recover the G5 I pulled it from...

At any rate, I'll get back to you on the liquid quantity.

PS - I did speak with Delphi support member (while they were undergoing reorg) and was told that the solution is just a refined version of high grade antifreeze. No water was used in the original manufacturing.
