Coolant filling thought - just an idea for the melting pot

Post by Fredalier » Fri Aug 06, 2010 3:01 am

Now, this is NOT a recommnedation. Nor have I even tried it, but maybe someone else before me might have tried, and maybe you have even been there a hundred times before in this site. After all, what would I know, bongfury has been here for nearly a decade and has 10,000 members, and I've only been herefive minutes and people want to ban me already, so what would I know. So at great personal risk, I ask. What if ... ... ...?

But what if ... ... ... ... ? (Remember this is just a "what if")

Have a look here as what I can buy for the equivalent of about 4 pounds.

http://www.trademe.co.nz/Home-living/Pe ... 945525.htm

Trademe by the way, outranks ebay where I come from by about one thousand to one. The Trademe site sold recently for $700 million dollars. (sorry back to topic now)

But what if - just a thought remember - what if that 4 pound item were used to pump coolant into an empty cooling system, in through the bleed hose? Of course the rad and xtank caps would need to be off, and the rad cap would need to be secured as soon as coollant spilled from the radiator, then the xtank would be capped and the pumping stopped when the xtank was at its high/low marks.

Any thoughts? (On topic thoughts that is)

No different to putting a hose on the bleed pipe, it won't eliminate the air pockets, but feel free to try it & get back to us with the results.
I think Simon Jones used a pump as part of a circulating system with some success, so that may be a similar line that may be more useful?
Also vacuum filling has been used with success, but you need to have a high enough delivery air compressor for it to work, most of the smaller type compressors that people may have at home won't get all the air out ( as some members have tried & found) & it carries the risk of cracking old hoses as they get sucked in (which is possibly a good thing, preventing catastrophic failure further down the road, or it may just weaken the hose prematurely but unnoticed to fail at a later date)

Not a substitute for bleeding of course, you can do what you want for bleeding. Spend hours bleeding if you want, (as apparently some people do).

My preference for bleeding for what it is worth, recognising that this topic is not "bleeding", but "filling", and recognising that our system is self-bleeding, but that aside, my preference for bleeding is to take my coolant-filled van for a short run, and let it bleed as it is designed to do, and then with the thermostat open from that run - and engine still idling - bleed any remaining remnants of air out. But look, I emphasise that's just my way, NOT actually recommended for bongofury members (or else I risk getting banned from the bongoFury site).

By the way, the item on Trademe I pointed to before, it's 240volts. Reckon I could probably find a 12 volt one to do the same, one that could be pretty well permanently mounted under my passenger seat. About the same price I think - brand new.

Would post a photo of it if I could, but it only exists in my imagination ... ... :wink: :wink:

Missfixit, do you have to copy the entirety of every post in adding a comment? It has a tendency to make the techie board a very cluttered place with no value added to it. May I politely suggest you press "post reply" rather than "quote". Particularly when there are photos involved. Not just for my sake, but for everyone's. Just a thought, just an idea. Doesn't even require a reply. I know what I have said, don't need it quoted back to me.

Why bother to use a pump to fill it if it's not going to aid bleeding? Don't see the point? :?
Since when is a bongo self bleeding? why did Mazda fit a bleed hose if its self bleeding?

I generally do just reply with everyone else (especially when photos are involved if you check) I don't need educating on the use of the forum ta :D
but in your case I like to quote just in case you decide to delete or change the content which makes the tense of the reply nonsense. also where many users reply to a thread quoting ensures the reply relates to the correct post:D

Very different from using a garden hose. Garden hoses use water not a coolant mix. That means for example, new coolant with every fill, even if (as we all know) we have to refill a few times while certain maintenance jobs are in train. Also it's hard to get a measured 50:50 mix by adding coolant later.

Besides, saying it's the same or otherwise as a hose, is not discussing the moot, nor is discussing vacuum pump -

So has anyone else got anything to say as regards this :wink: :wink: figment of my imagination. :wink: :wink:
When adding new coolant it's easier to put the coolant in first anyway (just add the required amount of neat coolant ie 5litrres) , I wasn't advocating the use of a hose :wink: why use a pump when it's easier just to pour it in?
Just seems like making it more complicated to me? :? Don't really see what it acheives TBH, no harm in it, but it'll still need bleeding.

Yep, as I already stated a long time ago, it'll still need bleeding. And you can bleed it till you have blisters if you want, as the video seems to indicate you like doing. Up and down, up and down up and down, up and down, up and down.

Or you can get Mazda to do it for you.

This is similar to what many Japanese Spanners do........ Being savvy and with them living in close communities so noise is a problem....they Fill from cold as usual, then bleed as much air as possible out of the system when the engine is cold......then start and IDLE engine until the thermostat opens....so that coolant is mixing (sometimes the stat is not fully open, just opening) take out the bleed hose bung, bleed out the air......then they take the Bongos out for a short run 2 to 4 km before checking.....and recommend checking the changed coolant level for 3 days....

Not done that technique myself but done something quite close.... :wink:

I'll try it today. Have got a (hopefully) small bleed to do, to check how much if any air has been left in by mechanic who did not appear to remove the bleed tube - my cut-back securing cable tie apparently still in place after coolant change. (Might have used vacuum fill but I'm going to re-check before discussing.)

I certainly don't think that any submersible fish tank pump I've ever used, would have the wellie to shift all the air out of a Bongo. That's why the Bongo is high-revved in the Mazda bleed procedure, to get a lot of wellie from its own water pump. A fish tank with sharks in it, e.g., Blue Planet or similar, might have pumps with enough wellie though - but would the bleed pipe take the strain - I doubt it. Interesting if Fredailer tries it - as Kirsty says, feel free.

Carn't belive what has been posted ...particularly in the locked topic
http://www.igmaynard.co.uk/bongo/forum/ ... =3&t=42472
As a involved bleeder in the much maligned series of 3 videos I think I am entitled to respond.
You don't need to be a brain surgeon to observe that the videos were produced to "help" the uninitiated to understand what is involved in bleeding (getting trapped air) out of a Bongo using that particular method. Sure, there were 3 people involved in the actual process, there were also people with cameras/makeup/security etc.........all this was to help continuity and not to be taken as the norm....Most of us know, and it is stated on this forum in many places that this method normally can be carried out by the average DIY owner (if the wife/husband joins in then it is a bit less of a hassel) in approx 30/50 mins providing there are no underlieing
problems.
