Green vs Orange Anti-Freeze

Hi,

I bought a second hand vehicle that has an orange colored anti-freeze.
I have a container(s) of the green colored type. Does it hurt if I added
the green colored type (when needed)?

Thanks in advance, Brad

Some antifreeze compositions are advertised to be compatible with all
other common types, but we dont really know what you have in the car
and what you have in the green jug. It is a lot safer to flush out the old
stuff and replace it with whatever you want to use.

I would not mix the two types without knowing more about their
compatibility.

Having said that, I ran some tests about a year ago mixing DexCool and
a typical "green" antifreeze dilution. When I went to buy the "green"
material,
every formulation on the shelf at Autozone claimed to be compatible with
other
types. I made the blends anyway, and watched them for a while at ambient
temperature, and nothing untoward happened. But realize that I did not
evaluate these for corrosion protection nor compatibility after cycling
through
temperature excursions.

I always use only Prestone Anti-Freeze.

Without knowing what model car and what orange variant it uses, the answer
is only: almost certainly.

If you put green in the orange then you are supposed to treat the
entire mix as if it were green and change it at the typical green
intervals rather then the orange intervals. If you bought it second
hand and don't know how long the antifreeze has been in it, or if it's
ever been changed, I would drain and flush it and refill it with
whatever color you want and you'll be good for another 3 to 5 years at
least.

Here's what GM says about mixing their orange/red Dex-cool with
regular green antifreeze:

http://www.acdelcotechconnect.com/pd..._04D-J-054.pdf

"Mixing conventional green coolant with DEX-COOL® will
degrade the service interval from 5yrs./150,000 miles to
2yrs./30,000 miles (50,000 km) if left in the contaminated
condition. If contamination occurs, the cooling system
must be flushed twice immediately and re-filled with a
50/50 mixture of DEX-COOL® and clean water in order to
preserve the enhanced properties and extended service
interval of DEX-COOL®"

I've been using nothing but Dex-cool in my 1993 Ford and 1986 Toyota.

Apparently it doesn't hurt at all, except for the extra cost of
changing coolant every two years instead of every five years.

If you don't "flush twice immediately and refill ..... etc." you
will still have coolant protection but you will face that extra
cost two years from now.

Good luck.

I have been hearing bad things about mixing them and leaving it
causing some clumping and other nasty stuff. I sure as heck wouldn`t do
it. KB

Mixing the two together is definitely a no no. Only use the green that
is made to use with all types.

The Dex-Cool "does' hurt. From mid 90's to around 05/6, the Dex-Cool
caused many engine problems, from clogging to causing leaks. There
were bulletins put out by GM. Class action suits, and I've worked on
many with the problems.
