Re: Which coolant?
AFAIK, Peak still makes an American Green, but you won't find it at
Walmart, KMart, or even Autozone. The discount stores seem to carry only
the Universal stuff these days. I have seen it at a Murray's Autoparts
near here as well as at a Citgo station and possibly a local NAPA.

Re: Which coolant?
If this newer and "safer for the environment" coolant is that
destructive to the cooling system components.............have there been
many complaints and lawsuits?
If so any positive results for the owners of the vehicles?
FYI (and maybe urban legend)
The VWs/Audis either call for G11 (blue color) or G12 (red closer to
pinkish color) which in the USA is blended by Valvoline. Valvoline
claims that no "over the counter" easy to obtain coolant has the same
blend as G11 or G12 and it is almost a "secret blend".
I am told that if G12 gets mixed with any other coolant it will probably
turn into sludge and other coolants will damage aluminum components. I
have not seen this yet...........thank goodness.
Now Pensotin makes a universal G12 that can supposedly be added to any
other coolant with no ill effects.
I have seen G11 coolant mixed by owners but have not really seen any ill
effects yet (See NOTE below). But either there is only a small amount
added or there is a leak that lets all coolant out anyway.
I have also heard that using the right coolant will allow components to
live longer without leaks.
I DON'T MIX G12, if it calls for G12 that is what it gets!!!
G11 seems to play with others OK and does not seem to be as proprietary
as G12.
NOTE: Now I do remember a couple of radiators (G11) that I changed that
had their radiator fan sensors that were badly corroded, or eaten up, on
the inside along with the threads in the radiators that were also
corroded. I am not sure what caused this problem though since these
vehicles were over 10 years old with probably no coolant flushes during
this period.
Now I did not mention oil which does not play well with any coolant! lol

the inside along with the threads in the radiators that were also
corroded. I am not sure what caused this problem though since these
vehicles were over 10 years old with probably no coolant flushes during
this period.
Now I did not mention oil which does not play well with any coolant! lol

Re: Which coolant?
If this newer and "safer for the environment" coolant is that
destructive to the cooling system components.............have there been
many complaints and lawsuits?
If so any positive results for the owners of the vehicles?
FYI (and maybe urban legend)
The VWs/Audis either call for G11 (blue color) or G12 (red closer to
pinkish color) which in the USA is blended by Valvoline. Valvoline
claims that no "over the counter" easy to obtain coolant has the same
blend as G11 or G12 and it is almost a "secret blend".
I am told that if G12 gets mixed with any other coolant it will probably
turn into sludge and other coolants will damage aluminum components. I
have not seen this yet...........thank goodness.
Now Pensotin makes a universal G12 that can supposedly be added to any
other coolant with no ill effects.
I have seen G11 coolant mixed by owners but have not really seen any ill
effects yet (See NOTE below). But either there is only a small amount
added or there is a leak that lets all coolant out anyway.
I have also heard that using the right coolant will allow components to
live longer without leaks.
I DON'T MIX G12, if it calls for G12 that is what it gets!!!
G11 seems to play with others OK and does not seem to be as proprietary
as G12.
NOTE: Now I do remember a couple of radiators (G11) that I changed that
had their radiator fan sensors that were badly corroded, or eaten up, on
the inside along with the threads in the radiators that were also
corroded. I am not sure what caused this problem though since these
vehicles were over 10 years old with probably no coolant flushes during
this period.

Re: Which coolant?
I can't help you with the proper coolant type, but you should be aware
that the system will hold likely 40% of it's volume inside the heater
core and engine block.
This means you will 'already' have a 40% water mix in there when you
start filling it with 'pure' antifreeze.
I always find out what the capacity is from the owners manual and add
half that in pure antifreeze if I want a 50/50 mix. I then top it up
with water. I actually have had 50/50 freeze up here in Ontario Canada
so I prefer 60/40.
Canadian Tire still sells 'green' antifreeze but be careful what you
buy. They now sell it premixed which is 'only' good for topping up, not
filling after a flush. And they charge more for the distilled water in
the premix, then pure antifreeze!
