Rad Flushing

Well guys just bought a new Thermochill TA120.4 the other day and have spent the best part of 4 hours flushing it.

All i can say is wow that was hard work...

Flushed it 3 times with White vinegar and boiling water, shaking for 10mins each.

Then flushed it with 5 kettle fulls of boiling water with bits still present untill the last 2 flushes with boiling water.

I then flushed it with 2 kettles full of normal cold water until crystal clear.

I then give it 2 flushes with Mayhems Ultra Pure H2O

Now i hope i have a clean rad for putting into my TJ07 tomorrow.

Has anybody else needed this much flushing ?

hmm, never that hard work normally. Not what ive ever seen anyway.

BUT, when i got my hands on an old vauxhall astra heater matrix to use as a radiator, corr that was gunked up to its eye balls.
It was that gunky inside that boiling water and that wouldnt budge it, i had to fill it with acetone, leave it to do its magic, then flush it out.
Acetone? talk about last resort, but it was well needed, and worked a treat..

obviously re-flush it with water after to clean the acetone out lol

i defo recommend acetone, as the rad is metal inside, and acetone dont corrode metal.
i have also used dot3 brake fluid before.
Works awesomely aswell.
I always find a use for dot 3

I had my whole system cooled by it at one point... (my old pc)
Worked really well too, as brake fluid has to have a high boiling point.

if i remember correctly, i did originally run distilled water for cooling, but then when i changed to dot 3 brake fluid, i think i dropped it around about 5 - 9C under load.

I would still continue to use it, but im not all into the colouring of it running through my clear pipes. i prefer UV coloured fluid.

dot 3?

What does that do to the plastics in your loop?

hmmm, i have never ever ever had any problem with using it mate.
I used to have dot 3 in my old 3D rendering Machine a couple of years back.
I had the same fluid / pipes etc for about 3 and half years without a single problem, then sold it on and i believe its still working to this day....
I sold it to my mate, so will get in touch with him later and ask him about it.

cheers
