To flush or not to flush?

babysnakes33 · 16 May 2014 at 17:14

Nearly ready to install a new loop using all EK parts apart from the addition of a second rad "Black Ice GTS-Lite 120".
After much research on the net, i'm now really not sure whether or not pre-flushing of the new radiators is necessary or not.

Thoughts please...

flush

yep definitely flush if it's brand new (but it wouldn't hurt doing it even if it wasn't)

babysnakes33 · 16 May 2014 at 20:03

Thanks for the advice... i'll do it anyway.

Depends on the make a lot of radiators these days come pre-flushed - I don't know which ones though!

Flush with distilled. Will need a more vigorous clean if an Alphacool (I have two so I say this from experience).

EK & Black Ice

My last 2 rads (Black Ice) were full of bits - so I would always flush

As above, flush to give your self piece of mind

Always flush. From experience pre flushing old or new parts can get rid of any potential unwanted hazards and problems. I flushed a new rad once and inside was full of metal shavings!

defo flush as there can be a lot of crap in the rads

Feser TFC Admiral pre flushed

All used materials are ROHS-compliant.
Once the cores are manufactured and the side panels and end caps Laser etched the parts are assembled by hand before being flushed and pressure tested all in house at TFC. This allows us to 100% control over the quality.

Sorry to hijack guys. I am going to be starting my first WC build soon. How and what do you use to flush your rads?
Thanks for any help.

Boiling water and shake like a mad man. Sometimes I don't even bother...I did with the Nova though as it's giant, got very few flakes out though.

+1 My arms felt they were going to fall off after numerous bouts of vigorous radiator shaking...

I've bought second hand radiator and I'm changing coolant.Is this the best way to flush?
Is it safe to leave it over night or it might be to long?Would I get better result with hot water?

Flush, Flush and then Flush again, just to be on the safe side

jimhaumman · 17 Jul 2014 at 17:08

I know you have to flush,but how is my question?
