rainx in windshield washer fluid

[spawningvat]

Ladies and Gentlemen;
I'm in a predictament: I changed the fluid in my cooling loop to a windshield washing fluid w/ rainx because i was looking for a new color and this bright orange liquid caught my eye. My temps worsened about 4* bringing me to 38*c. I was wondering if the rainx additive is a surfactant? Would it be interfereing with the efficieny of my loop? If yes, how would you go about cleaning it? Should i just empty it and refill with generic blue windshield wwashing fluid or should i run a cleaner through it for awhile?

Also, of the 2 90mm fans i have pulling air through my core, i volt modded the remaining 12v one to 7v, so now i have 2 90mm fans both at 7v. Would this have that much of an impact on my cooling? I just finished soldering the wires and its a pain to drag everything downstairs, take apart the molex connectors, heat up the soldering iron, waste more heatshrink tubing, etc.

so whats up? is it my fluid or my fan that is causing the temp increase.

Thanks in advance.

edit to make more sense

Rainx is a water-repellant oil. On your windscreen, it makes sense to have water not "wet" the glass, but rather bead-up and run off quickly. In your cooling loop, you want to have the water contacting directly with the metal, not be seperated with a thin layer of oil.

To remove it, you'll need to use some sort of detergent.

By the way, you should be able to remove the pins from a molex connector without any soldering. Look for the little tabs that hold the pins in. Or, splice in some insulated spade connectors for easy change-ups.

Speaking of weird additives... I'm on "Toliet Duck" ATM... and I don't seem to have any difference between that and the antifreeze mixture with the added bonus I'm running "pine fresh" instead of "engine fresh".

I ran 2 weak mixtures of simple green and water thru the system, which turned to a chocolate milk consistency. Then flushed it out with constant tap water for a few minutes, refilled with new generic blue windshield washer fluid, and now i'm kicking it at 32*c idle, about 36*c under load according to mbm from the onboard temp probe. ambient is 30*c. not bad for the cheapest relatively good system i could through together.

My friend just spent $90 on a dtek whitewater and a 120 fan, i spent only alittle more on my whole system. Scratch and dent d-tek blocks are excellent, especially after lapping to 1000grit.

thank you groth and boli

Are you saying you run windshield washer fluid in your loop instead of water?
This sounds very interesting.
What are the pros and cons on using it?

well dsptech

Sadly my windshield washer fluid has gone the way of the dodo. I was using if from last year, 2003, until about march 04. I went to empty my sysyem, clean it, make a new reservoir, and refill. Well, I figured, I might as well pull the block, clean it and check the o-ring. Well I have a dtek tc4 with the coiled springs thru the passage, and there must have been pigments in the windshield washer fluid, because i had large blue rocks forming. So the windshield washer fluid idea was scrapped. I sanded the inside of the tc4, wire brushed the springs, used ketchup to clean up the copper a little more, and reassembled. From about March, until now, December, I have been running antifreeze and water in somewhere around a 10:90 to 20:80 mix. This is just eye balling. I miss the blue from the windshield washer fluid, but that is all. Temps with the antifreeze are better: right now 33 ambient case temp, 34 idle, load gets to 36-37. Evaporation is less with the antifreeze. And the smell is decreased with antifreeze. Plus my tubes aren't as cloudy, as when I had the windshield washer fluid.

Oh yea, one more note: my tc4 is the aluminum top one, and i noticed a little pitting on the underside of the aluminum and the anodizing was chipping away. Hopefully, the antifreeze/distilled water mix will be enough to prevent further corrosion.

antifreeze/distilled water is where i'm at right now. I also switched over my friends loop from windshieldwasher fluid to antifreezee. He has a dtek whitewater, and the blue gunk was clogging up his fins.

There you have it
