I had written a masterwork diatribe for the mcw6000 thread and was about to click 'submit', when my monitor went dark. Okay, so room temperature had gone up 15 C with this week's sudden influx of spring, but WTF?! Taunting communications majors who can't write shouldn't stress my baby at all.
As I reached towards the reset button, I heard a terrifying sound - a choking gasping gurgle. In a haze of adrenaline, I dived under the desk, fumbling in the dark tangle of cables. As the wet coughing noises grew louder, I found the master kill switch on the UPS. Silence. 'Twas with great trepidation that I then pulled the side panel off my black beast. My worst fears were realized at the sight of a pale green pool spreading across the smooth steel bottom. I died a little as I looked up to see a thin drizzle pause briefly on the back of my video card before continuing downward. My heart has been ripped asunder -- the heater core of my dreams, a beautiful copper lattice with shining brass ends, has betrayed me. And wrapped in its inexplicable suicidal rage, it murdered an innocent video card and grievously wounded a shy, quiet pump. ![]() |

Just wash off areas that have gotten your coolant on 'em with plain distilled water and let 'em dry (hairdryer or put in sealed container with silica gel packs) and chances are good you electronics'll be OK.
Bummer about the leak ![]() Any idea what let go? |

you can also try to pour the whole card in an Isopropyl alcool bath, wash it and let it dry a good 24h.

ok, leak detection 101
most hobbist electronics stores have water sensor kits for ~$10 that have 2 contacts and sound an alarm when wet - use pieces of screen insulated with a paper towel on the contacts, and tape to the underside of all wbs, etc. near the mobo or video card this can be rigged for a hard shut down as well (works to preclude disasters on unattended test benches as well) |

You have my sincere condoleances.
Your story was quite gripping! Do you write novels on the side? ![]() |

Update: The pump was a direct drive landscape one made by Beckett, intended for...waterfalls!
![]() The video card, a radeom 8500, has an ugly burn mark around the leads of a capacitor. I've washed it well and set it to dry in front of a fan. Whatever. The heater core - ![]() All in all, it wasn't too bad. Nothing important was destroyed, and I only lost seven hours of folding before if was back up. Plus, I had a chance to show off my purple-prose. ![]() |

Did you test the core before you installed it, originally?
Any idea what the cause of failure was? Stress on the pipes/solder joint? |

Not only did I leak test before putting it into a computer, but I had leak tested it for years when it was in my van! (I removed the heatcore and blower before I sent my dead van to junkyard last spring.)
I don't know why that join split, and that bothers me. There would have been some stress on the inlet/outlet from the weight of the hoses, but that shouldn't have been significant. The core was held in place by a strips of wood screwed to each side, then bolted to the top of the case. Shouldn't have been any stress from the mounting. The whole system is brass and copper, no signs of corrosion anywhere. ![]() |

ah, the salient fact emerges: a 'rotten' core
no tears please, that was earned |

I admit to surprise, this lash-up from the inventor of the Grothmeter ?
EDIT: I'll add a bit; at the onset of WCing all the kids headed straight to the wrecking yards and then regaled all and sundry with their tales of woe and ruin as the rotten cores eventually started leaking some like cheap pumps, others rads - so it goes Last edited by BillA; 05-08-2004 at 10:58 AM. |

Heater cores have life spans of decades. (Have your ever replaced one? Know anyone who has?)
Surely you're not suggesting that a year filled with water/HydrX is more damaging than 10s of years of water/glycol exposure? |

the phrase 'rotten' is not mine, it is the expression used in the industry for old cores
yes, like any part under stress it has a finite 'life' and it could have been bumped, or simply had a 'thin' soldered joint; who knows ? also yes, over the past 40 yrs of owing cars I have indeed replaced several heater cores (4 I think, but I drive old stuff) - had an Aerostar with a leaking core that was 6 yrs old -> my daughter's '83 Fairmont has a leaking heater core, the ENTIRE goddamn dash has to be removed, bummer - #5 I guess now |

![]() I'm thinking that solder joint was weak from the beginning, but had never been sufficiently stressed (original leak test was with just a 6 ft water column). The recent rapid rise in room temperatures, combined with a sealed-system reservoir that contained more air than it ought, could have increased pressure enough to pop a weak joint. The core has held 10 PSI for a day now, so it'll go back into service tomorrow. I would have take both cores and blowers from the van, but it too was a vehicle that wanted the entire dash removed, plus a weird structual beam under the dash. |
