Quick Question?
Dumb Question -- What type of engine coolant are you guys using? Mine is running low and needs to be refilled and me being the engine incompetent person that I am I have no idea what to get?
Thanks

Never a dumb question.
The handbook says:
Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add only
DEX-COOL extended life coolant.
and:
When adding coolant, it is important that you
use only DEX-COOL (silicate-free) coolant.
If coolant other than DEX-COOL is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner -- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the
use of coolant other than DEX-COOL is not
covered by your new vehicle warranty.
I'm sure other members will chip in with other options despite the health warning.

I don't think it's so dumb. A year or so ago I was in the same situation. I went to the Autozone to just stop in and pick up a gallon. Found out there are TWO types of antifreeze. One is for older model cars and one for newer. They are different colors too if I remember correctly. There is a term for the newer one, but I cannot remember what it is.
Otherwise, prestone....

If you decide to add water - deionized or distilled water is the way to go. Don't add the green stuff. Make sure it's red and it says Dex-Cool on the jug. You might also look for something on jug about GM, etc.
