I have a litre of Dexron V1 on the shelf for some reason. Did I buy this for Power steering? If so is it correct? :-\ :-\ :-\
-
:-\ maybe. I use dexron 2 in mine.
I read somewhere on here Dexron 3 attacks the seals.
-
Dexron 3 is backward compatable, so to is Dexron VI but upgrading to this in your autobox may give unwelcome gearbox performance if not done correctly.

I would like to know if it is suitable for the power steering. I use Dex.111 for my autoboxes. :y

I'm sure I used Dex 2 when I topped mine up. It is said that Dex 3 will seep past seals. I know now that the PAS fluid was only over topped up by previous owner with 'whatever was at hand/free/cheap' but never changed under his ownership. So about 11 years minimum (7 years SORN, immobile) on a blend of various oils, possibly the original from the factory! ::) Ohh dear!
Not saying either the seal story or old fluid thing are myths, definitely (given the cost) worth getting the 'old' Dex 2, which your Vx dealer probably won't be able to supply, but every cheap n cheerful motorfactor / ECP etc will still stock. :)
-
Power steering dex 1or 2.
dex 3 is fine in gearbox, rubber pipes on power steering don't like dex 3, ends up leaking out.

Just rang stealers, sound chap I know well. He says Dex V1 is backward compatible with Dex11 for Omega power steering. :-\ :-\ :-\

From TIS 2000 - Field remedy 1570
Models : Vivaro 2001...,Movano 1999...,Omega-B 1994...,Frontera-B 1999... All
"TIS 2000 indicates that the power steering oil specification for Vivaro is
Dexron III. This is now incorrect.
The original fluid was Dexron III (PN 90 510 269, Cat-No. 19 40 763) which
was used to service certain power steering and automatic transmission fluids
(ATF).
This oil is no longer available so a new version of oil Dexron III has been
specified for the affected ATF (PN 93 160 372, Cat-No. 19 40 712) however
this oil is not compatible with power steering systems and should not be
used for this function because this may result in leakages.
To service the power steering system the oil now specified has reverted back
to Dexron II (PN 90 350 342, Cat-No. 19 40 700).
This should prevent any confusion when trying to select the correct oil for
the correct application.
NOTE: This information is valid for all models except Sintra (partnumber
90 513 486, Cat: 19 40 707) and Astra-G/Zafira/Vectra-C/Signum (partnumber
93 160 458, Cat: 19 40 715)."
HTH :)

This was exactly the same response I had from mine. I think it was Mark DTM who said the long-term abilities fo the new Dex VI are not yet known. (apologies if you didn't say this Mark/mis-quoting you) :) Not saying Dex VI is bad, or por quality or wrong, just that the pump was never designed for it, and so we have yet to see how 10 years of using Dev VI affects the PAS system :) But we do know 10-20 years of Dex 2 in Omegas works fine.
the 'quality' of Dex2/3/VI whatever isn't so much as issue as it is with say, a wheel bearing. Think of it more like antifreeze. So long as you have antifreeze, the name on the bottle isn't massively crucial. What I'm saying is, if you buy the cheapest bottle of Dex 2 you can find, you're not using 'inferior' quality gear in your car. And more damage can be done using genuine GM Dex 3, then noname Dex 2 :y
I went for Dex2 from ECP and had 6 months no issues
-
And to answer Entwoods post - thanks for that. Begs the question how on earth are Dealers meant to service owner's Vivaros/all other models if Vx have effectively axed Dex2?? Unless they have gallons of the stuff in warehouses they're just not selling it? I got the impression they 'recommend' the DexVI because there's no Dex2 left?
Hmmm.....
Sounds to me like Dex2 is a 'good old faithful' oil, which causes no maladies, whereas the newer stuff seems to be.
Also I'm glad I didn't just take the dealer's word for it, and buy the DexVI!! As a general rule - never trust the dealers!!! :y
-
Just buy a cheapish, mass produced car like my Astra. You can put cat piss in that without detriment.
-
Hmmm, makes me wonder, as I can't think why I have the Dex V1 on the shelf, other than that VX sold it to me when I had to top up my system two years ago when I changed a damaged power steering pipe. If so that begs the question, did the fact that I topped up with (according to TIS) the incorrect fluid, ie Dex V1 instead of Dex 11, cause my pump to fail??? :-\ :-\ :-\

That must be quite an old vintage of oil by now, Shackeng!
https://en.wikipedia.org/wiki/DEXRON (https://en.wikipedia.org/wiki/DEXRON)
Poor old sperm whales. :'(
As you can see, development of the standards has been an evolution of fluids with basically the same properties, so I wouldn't have thought the choice would be that critical, especially in a PAS system where it's not subject to the contamination nor extremes of temperature found in an autobox.
I read the compatibility issue with DEX III in PAS systems to be mainly down to a single version of DEX III adopted by GM dealers, so an aftermarket DEX III might even be OK.
Certain products might be hydroscopic, so if it's been on the shelf for too long, it might be best to give it a miss if the bottle has been opened, as a PAS system is not likely to get hot enough to drive off any absorbed moisture.

Mine is Dex 6 Kevin, which was apparently developed by GM & Petro-Canada for auto transmissions on vehicles 2006 and later! I'm not sure as to it's hygroscopic qualities, but as you imply, possibly on a par with brake fluid. :y
-
Ahh, OK. I misread it as DEX I. ::)
I would say you'd be fine with DEX VI, as they have most probably sorted out the compatibility issue since DEX III. As said, though, the only fluid that has been proven over many years of use in that system is DEX II. You pays your money...
-
Dex 2 is readily available from shell its called donax. There's a synthetic one and a mineral, and is widely used in plant and commercial applications. I've been using it for years, in carltons and now omega, gearboxes and power steering.
-
Having just read through this: https://en.wikipedia.org/wiki/DEXRON#Dexron-VI which describes the development of Dexron I am none the wiser. Which version of Dex 2 are the current products that are available to buy? :-\

To much information, you are suffering from. Go to a lokal hydraulic hose repair, eg(pirtek) or agricultural tractor place, dex 2 is still widely used.

But did you read this paragraph BG?
Dexron-II, IID and IIE
Dexron-II was introduced in 1972 with alternative friction modifiers such as Jojoba oil. However, it caused problems with corrosion-prone solder in GM's transmission fluid coolers;[2] accordingly, corrosion inhibitors were added to the product. The resultant fluid, released in 1975, was called Dexron-IID. However, the corrosion inhibitor made the new fluid hygroscopic, which while it was not a major problem in automatic transmissions, made Dexron IID unsuitable for other hydraulic systems in which it was commonly used.[2] A further reformulation to address excessive hygroscopicity was named Dexron-IIE (GM Spec GM6137M).
e.g. Power steering, so my question remains, what version of Dex2 is available? If Dex11E, that's OK, but not Dex 11D, unless a programme of regular fluid changes, as adopted by some, is instituted. It seems, according to Wiki, that GM no longer endorses the spec of anything less than Dex V1 :y
-
Any DII should be fine. I use the cheap shite that Hellfrauds sell for about £4 (trade) for a small bottle. Mainly for convenience rather than anything else.
-
The dex2 you are buying will be the last spec, before it was superceded by dex3,. I use spirax s2 atf, exceeds and meets all gm,mb and voith specs.
Or as TB said just go to Halfords and buy there atf fluid, which will have spec available on line,. :P

:y :y :y

Just checked in my fastidiously kept, accurate excel file of my car's service history, as sadly all it states is 'Dexron 2' however, I know I bought it from a euro car parts depot place, while we were on a weekend away. It was £4.80. The best bit was, given the guy had never seen me before, I wasn't local, I thought I'd chance my arm and say 'what's trade on that?' - which he answered 'uh, that is trade, mate'! whatever it was about by voice/appearance/cleanliness said I was a mechanic!?! :D :D
If the bottle's still kicking around I'll try and find it, but TB's price is about right. I don't really think there's such a thing as 'poor quality' atf, vs 'good quality' the only difference is price. :)
-
I've just checked the spec of Dex11 at CAF, or whatever they are now called. It states" Complies with Dex11D and Dex11E. :-\ :-\ :-\
Given the statement in Wiki above, this means that it is both hygroscopic and non-hygroscopic at the same time. Go figure. :y
I think I'll stick to the GM DexV1 which GM specifies for the PSF. :y
-
OOF recommends sticking with Dex VI, however, as I found out, there'd been all manner of different 'Dex's' put in my PAS system prior to my ownership, whatever was hanging around work/dregs left in a bottle etc it seems, and there are no leaks to be seen on my PAS system. So we'll see for a long-term test on yours :)
