Here's one for ya'all to chew on.  BTW, if you have G-12 coolant, this may
not interest you.  If you love VW-service-is-incompetant stories, it might.

I decided that I wanted to flush out the G-11 coolant in my '95 and refill
with same (I won't go into why I don't want to switch to G-12).  Anybody
here ever try to get G-11 coolant?  Anyone ever have a container of it in
their hand?  I'd like to know where it came from.

I've been to three VW dealers in the St. Louis area and NONE of them have
heard of G-11 coolant.  As far as they are concerned, it doesn't exist.
They looked at me like I was nutz until I showed them page 94 of the owners
manual that specifies it and the coolant tank cap that specifies it.  I even
listened in to the phone conversation one parts manager had with the Chicago
VW parts warehouse.  THEY have never heard of G-11.

What they have heard of is either G-48 coolant, which is blue but is NOT
"lifetime," and G-12 (red), which we all are familiar with and IS
"lifetime".  They all tell me that G-48 is the only thing that was used
until the switch to G-12.

So, faced with this confusion, I called VWoA.  They will "research it" for
me and call me back.  Sheesh.

Now, in the mean time, can anyone here clear this up?  Todd?  Deecee?

Any of you want to place bets on what VWoA tells me?

I thought maybe the G-11 in the manual could be a misprint, but then there
it is again on the filler tank.  I do know this -- if there really is a G-
11, I'm going to lambast VW for such poor communication with their dealers
regarding something like this.  Same goes if there is no G-11.  WTF is in
the manual and on the tank for?

Had to share -- thanks.

The hunt for G11 -- latest in the saga (or, what's the definition of
"absurd"?):

While out at lunch today, I got voice mail from a VW/Audi customer service
rep at VWoA.  The message stated that the coolant I needed for my '95 GTI-
VR6 was "definately G11".  Okie-dokie.

In the mean time, I'd emailed an order for G11 to Suntrup VW dealership
(www.suntrup.com) specifying ONLY the part number ZVW-237-104.  They call me
at work about an hour after VWoA calls and tell me ZVW-237-104 is the part
number for G11 coolant (DUH) and BTW, hadn't I been in there looking for
that last Friday?   I said, "Yes," and reminded the parts dude that he'd
told me there was "no such thing" as G11 and he'd never heard of it, blah
blah.  He then tells me that ZVW-237-104 has been replaced by ZVW-237-105,
the G48 coolant, and they have that in stock and come and get it.

I tell the parts dude that I just got word from VWoA Customer Service that
what I need is "definately G11".  The parts dude tells me that VWoA doesn't
know what they are talking about. (Possible, I grant you.)  I remind him
that he told me there was no such thing as G11 even though it is in the
owner's manual, on the filler tank, and there is a part number for it
(tactful, eh?).  I also remind him he told me that G48 is not "lifetime." I
inform him that G11 is "lifetime", and so, how can G48 replace it?

Next, I ask the big question:  Are the two compatable?  Will there be
problems if I try to add G48 to G11?  He stammers, finally admitting he
doesn't know. #@$%&@#!!!

I called the VWoA Customer Service person back and left voice mail asking
about G11 vs. G48.  We'll wait and see.  Hopefully I won't be out if/when
they call back so I can fully discuss this and share my innermost feelings.

Your wrong and right at the same time, Rich.  VW touts G-11 as being
"lifetime" (note all my references to it as "lifetime" have been in
quotation " " in order to signify VW's point of reference on this).  Says so
right in the '95 manual on page 94.  They again said this to me on the phone
the other day.  So, you're wrong -- it is "lifetime".

:-)

And, your right.  It is generally agreed upon here and in the archives that
"G-11 needs flushing periodically and is a lesser quality coolant than G-
12."  My belief that it needs periodic flush and fill is why I went looking
for it in the first place.  Hell, I'm skeptical about the G-12 being
"lifetime".

I do not want to switch to the G-12.  There is no evidence yet that it is
better, though it probably is.  The main thing for me is I won't have to
worry about any incompatibility -- any old coolant lurking in a passage or
gasket -- if I refill with G-11.  I figure I'll be OK if I flush and fill
every 18 to 24 months with G-11.

If it exits.  :-)

As far as the G-48 goes, it may be a replacement and be OK.  But, remember
the dealer didn't even know about G-11 -- "Never heard of it."  So, I don't
trust them knowing squat.  They told me all VW's came with G-48 until G-12
came out.  That is definately wrong.  G-11 was used in '95's and (some)
96's.  And they couldn't tell me if G-11 and G-48 were compatable.  Would
you be ready to trust the dealer and add the G-48 to your car before you
were sure?

VWoA called back today and gave me the part number for G-11 -- the one I
already had (ZVW-237-104).  I tried to explain that the dealers don't know
what that is, no longer carried that, had G-48 instead (ZVW-237-105).  I
gave them that part number.  VWoA had never heard of G-48 and that part
number did not show up in their computer!  Again EMPHASIZED that my main
concern was/is are the same and/or compatable because the dealers sure
didn't know. They said that they'd call back.

Two hours later they called back and said that the part number I gave them
for G-48 was G-11.  The two were the same even though they now have a
different part number and a different "G" number on the container.  Why'd
they change the numbers?  Still sounds fishey to me.

I am now going to have to ass-u-me that all this is right.  It still
astounds me that three dealership part's dept's had never heard of G-11,
VWoA had never heard of G-48, and that they change a part number and letter
designator on a substance (coolant) but make no change to the coolant.

I give up.  I also wish Arthur Emerson all the luck of the gods in dealing
with these people.
