Here's what you can expect when you clean a PA 120.3 rad with 5% distilled white vinegar.



I'm now on my sixth pass and third gallon of vinegar and somehow not feeling incredibly optimistic that this will be the time when I get clear vinegar coming out. It just doesn't seem to be getting any better.

At least the fifth time appears to have less sediment settled at the bottom - but then again maybe I just haven't given it enough time to settle.

haha, each time I soak, I then use the hose with flush out the rad, then put more vinegar in. Takes a little longer, but with the adjustable nozzle on the hose I can get some decent water pressure going through the rad to help clean out residue.

[vyper]

So did you get vinegar coming out looking the way it went in with that method?

its still getting milky, but not as bad, less a little each time.

When I do it, I use the pray nozzle on stream, and put it through both sides of the RAD.

i wouldnt worry isf the vinegar is milky... but if you let water pass through and it becomes milky, use more vinegar

I've heard Scrubbing Bubbles or something gets the job done in about 1 try. Maybe you can give that a try.

Have you tried filling with vinegar halfway and shaking the !@#*$&) out of the thing a couple of times? After about 10 good half fills + crazy shaking alternating water and vinegar (which pruned my fingers), I only needed one good 6 hour soak to get the rest out. Of course, I followed up with more shaky shaky and another soak for insurance and it's clean now. Currently, I am having my system flowing outside the computer until Core2Duo to find out if my tubing will get whitestained again.

However, wierd thing is that I had a good bunch of black "specs" coming out of my PA120.3

i use SB and it cleaned well, i did it 2 times for about 5mins each... then i soaked in vinegar overnight, and the vinegar came out milky..


when i did it, i put in a bit of water then sprayed foam into the funnel, then washed the foam into the rad. this time i will use straight foaminto the rad.

FYI, the sprayer end fits onto 7/16 tubes

but for the first 3hr vinegar soak, some came out, then the SB soak #1 the rest came out.

Persevere! This is my what my 6th vinegar soak looks like and you can see the difference:





Yeah it's a lot of work, but I'd say it's worth it.

I used denatured alcholol to flush a vehicle A/C Condenser once. I wonder if it's effective on PC rads also.

[V I P E R]

I use denatured alcohol with the vinegar and it is faster to clean the rad.

Congrats to you! That is really sparkling clean water!

Very patient...
Nice work!

[DrBlink]

Keeping on topic... 6 seems to be the magic number to how many wipes of vinagar is needed. Cleaning the rad is soo tedious and a true test of patience but I passed and so can you!

I assume this would work on a heater core as well?

[pie_uk]

distilled white vinegar , hmm ok will have to go and buy that. i just used normal vinegar on my gt 240 rad and that cleaned it very well. the tubing never went cloudy.

[ramenchef]

If you're using a thermochill, hot water is the best route to go according to Marci as they used water-soluble flux. That should help a lot with the cleaning.

[serialk11r]

NOOOOOOOOOO stop it!!!!!! NO VINEGAR!!! I don't think the no vinegar ONLY applies to thermochills lol use your brain.

[ramenchef]

I only mentioned thermochills because that's what the OP has lol. But yea, for others I would think isopropyl alcohol would be best.
