KaptCrunch Posted December 13, 2004 Share Posted December 13, 2004 Correction for mixture of PG Not my type-o, but KaptCrunch's. :rolleyes: All of my posts state 33% Propylene Glycol to 66% distilled water. :winking: Stev 100 lashes ......sorry for type-0h-graph thanks for correction 1cup PG 2cup DW Note: if Sierra propylene glycol not availible use Prestone LowTox EPA approved anti-freeze(white jug) As for cleaning the inside of the HC. We call this "flushing" the system. It's very similar to flushing an automotive cooling system. (note fill cap is closed on unit) Basically, you will need more of the Sierra propylene glycol and distilled water mix an (newbies)a power bar with a switch an old AT PSU to power only HCX pci slot card. (pros) disconnect ATX plug and power to all but HCX card an do the trick. i left this info out to protect your investment. Splice the inlet tube coming out of the back from the HC external unit.(The LOWER connector@rear) Cut tube where its convienat to work with, the tube coming from the computer side, will dump the old coolant out into a gallon or so size bucket, while the other splice end draws into the HC a fresh new coolant pre-mixture from your jug. Use a glass jar so u can see whats going on; keep the sucking tube in fluid at all times DO NOT let tube run dry, damage the pump if do turn off pump to refill jug or jar. HCX(lower)================suck===/splice/===blow===========PCI You will then need an Eldon-James 1/4 to 1/4 tube coupler to reattached the splice or equivalent, after completeing flush-change. If you do have algae or other foreign items in the system, you will need to mix well ONE part White Vinegar and TWO parts distilled water for cleaning. after cleaning system, flush really well with lots of distilled water. Then you will need to replace back in the Propylene Glycol mixture- 2/3 cup Distilled Water, and 1/3 cup Propylene Glycol. 3.87oz distilled water per PG quart or 30.3ml distilled water per PG liter. 1 oz's PG + 2 oz distilled water = 33% White Vinegar is also recommended for cleaning coffee makers. It does an excellent job at that too. DO NOT USE baking soda internally to the system or any automotive flushers. This will ruin the micro-channel cold-block and is too abrasive to the flow indicator wheel housing. Stev thanks Stev Link to comment Share on other sites More sharing options...
