VY V6 Radiator Flush

[greenacc]

I stopped buying them after consulting the VS one for some transmission assembly detail. All is said about the trans is pull the pan off replace the filter and put the pan back on...!
I sent them an email asking what gives have you missed 20 pages in my book??? And they replied saying " it's a service manual not a workshop / rebuild Manual!
I replied saying goodbye to as I'm no longer a customer

Yes I am that fool and his money who is so easily parted!

Having trouble trying to remove the cooler reservoir on the VY. It seems to be placed under the air filter box and I can't see anyway of getting to it to remove.

In my ute beaut instructions from Hayes it sayes it's held there with just 2 screws. That maybe so on another model but not with the VY?

Cheers,

Well I did the flush but to be honest I'm not sure if Ive done it right or not? I only got about 4 litres out when I drained it. Didn't seem to look too bad with what I got out of it, just not enough, and then when refilling it only managed to get about the same 4 litres of concentrate back in. Hopefully with what must have been left in the system and what I put back in the ratio is somewhere around where it should be.

I took it for a bit of a high speed run and could not get the temperature needle past halfway, so here's hoping.

Cheers,
John

Sounds like it should be fine if you put the same amount in as what came out. Check it again in a day or two just to be sure.

Now I'm not so sure after reading this Gates guide to the proper flushing procedure. It makes me realize how little I actually got out of it.

Do how did you drain the system? I would have just dropped the bottom hose off the radiator, flushed fresh water through it with the hose and filled her up with fresh coolant/ water as required.
If really keen fill with water and run with heater on for a few minutes to flush out the remaining old coolant then drain again and fill.
Unless your old coolant was rusty I wouldn't worry and just leave it.

Yeah,
That is pretty well what I did, but so little came out compared to the supossed 12 litres that should have been in there. Considering when I looked in both the radiator and the reservoir the other day and could see nothing in either perhaps that's all that was in there. But it doesnt account for the small amount I could only get back in?

The rest is still hiding in the engine block and heater, that's normal.

I've been using Nulon red concentrate. No difference in price to the green really.
Red does also have the benefit of easily being able to spot leaks though which is a plus.

It's different formulas meant for different motors. It's not just a matter of different colour.....
