Coolant Issue:

I recently changed my coolant, and didn't know I had to use the GM approved stuff. I'd never heard anything about it. I put the green stuff in.

Now what? I went down to AutoZone and picked up the good stuff, but the guy behind the counter told me to NEVER mix them.

Now what? Do I have to go pay to have a coolant change paid for so I can get the stuff out of the block?

Thanks fellas.

or you could buy a backyard flush kit from autozone...but do not mix them! I also remember reading somewhere on here that the green stuff is not formulated for aluminum so get it out as soon as possible.

Ah ha. Many thanks guys. I didn't even consiter running the car with an open radiator, but that seems like the best idea.

Thanks again.

I have called a GM dealership about this before, because this was one of the many mistakes I've made on my car. As I have been told, the 2 fluids are incompatible, and the green coolant will have a tendency of attacking the block. They also said that my coolant will need changed every 20k miles instead of the regular schedule that's listed in the manual.
