Default Coolant Flush

I need to have the DexCool in my 99 Bonne flushed. Does anyone know a good place to have it done in the Twin Cities area. The dealer near me will do it, but they put DexCool back in. Also, will any "green" coolant do, or does it have to be the Prestone Dex compatible or Prestone Long Life? Thanks.

Any green will do but you have to watch the Dex compatible one - sometimes they're just green dex. Most people use the Prestone Mix with Anything type.

Just about all shops will flush-n-fill, even the oil change places; or you can do it yourself with a Prestone Flush-n-fill kit (about $3.00 at Walmart), 2 gallons of coolant, a screw driver, and a garden hose. I recommend actual distilled water ($0.86/gal at Walmart) for the mixing with the Prestone.
