I think I got yelled at for posting this in the wrong forum. Sorry.

I was wondering how we felt about Prestone's 'any make any model' coolant. It says mixes with any anti-freeze. Is this stuff safe for N*'s or should we stick with the pretty orange DexCool?

well in a pinch its ok, its really their own blend. I used the Preston GM approved dexcool when I did the coolant change. They make all sorts so be careful which you choose.
