Hi guys,

Struggling to bleed my first loop atm.

It's external on a rad stand (large rad), all the air is in the rad/res/pump.

Is it ok for my d5 to make a light buzzing noise while running during bleeding? I ask because I was under the impression any noise = super bad.

Atm my res is ~75% full, when i turn on the pump it will drop to ~60% and start to buzz. So I turn it off immediately and it shoots back up to ~75%.

cheers

ps. feels like i've been shaking this rad around for a lifetime..

Keep it on full power, it's normal for it to be fairly noisy during bleeding.

Try turning the system on and off rapidly or changing the D5 settings to 1, the 5 quickly
 
Th ok so the noise is fine for now?

To clarify, it's not running dry at all. It can't be air in the pump because the res is directly above it..

Just after posting this I finally managed to get an air bubble the height of my 600t (in 3/8) tubing out of the rad LOL. still loads in there though.. Looks like I'll be opening my third bottle of mayhems, too.
 
Had a similar issue with a Phobya 1080, pump buzzed (I thought it was knackered too).

Turned out to just be a huge air lock in my system, turned the pump off, slackened one of the fittings on the radiator and let the air bleed out direct, as soon as I did that I could see the fluid following the natural route of mavity.

Also as I presume you have QDC's on the radiator, put the radiator on end, grab a funnel and fill it up, should save having to bleed all that air out.

Well, after coming back from my dinner there's coolant leaking from the join of both quick disconnects, 1 of which is already a replacement..

*le sigh*.

Can anyone recommend any that work? these are the phobya ones. pretty sure ocuk don't sell them, but i'm thinking koolance? $$$ though..

I've only heard good things about the koolance ones, especially regarding flow rates. Most people say they're worth the money
 
thanks. mind boggling finding the right pair though. ah well.

I guess since the phobya pairs i bought are less individually than half a koolance pair, this is going to be one of those "buy cheap buy twice" situations.
 
one thing i will say about koolance qdc are the (red) o rings are really soft silicon as the compres slightly with a very pow pressure more so than normal black (nytram i think they are) ones and they are easily damaged. to get replacements locally as in a oring stoe is not easy as the ones you will get of the shelf are to stiff and robust a material to compress enough and then you have hell of a job getting the qdc togaether

so protect your seals the red ones are easily damaged.


you can feel the diference in the density of the material easily with your fingers btw the koolance ones are spongy
 
Partial success.

@craac the only o-rings on the vl3n series QDC fittings were on the male half of the qdc mech, none on the compressions. Do you have the same ones?

Anyway: I ghetto-filled my rad in the bath (same way I flushed it) I shook it around like a madman, I'm only a little guy so it was like a workout lol, and filled whenever I could. Thanks to pgi947 for that suggestion. Made a hell of a mess though.

Thanks to that and the koolance qdcs my pump no longer buzzes or struggles. I think those rubbish phobya qdcs must have been really restrictive alongside the airlock, because atm I can hear sloshing in the rad (d5 on 5) so I still have lots of bleeding to do.

Not a single drop from the qdcs either :).
