Radiator Flush
I have 4.5 years on a radiator flush on a 97 c5 - stock. I have read horror stories and urban myths about Dexcool. First question is whether I need to have it changed - 30k on the flush. The second question is whether I do use Dexcool or something different and if something different,what? You folks have always been the best for advice.

I drain and fill every year with DexCool and Distilled water..
Never any problems in any of my GM cars.
Dexcool is like any other "long Life" coolant...
Make sure you change it every other year or it turns to ****.

Replace your coolant and use Dex-Cool with distilled water. Distilled water is mineral-free and it's cheap.
