From previous on this site, TriedaqJul '13 I owned a 2006 Chevrolet Uplander which, on the recommendation of my independent garage, had the radiator flushed and the Dex Cool replaced with universal coolant. That was three years ago in 2010. My son now owns the Uplander and there has been no problem with the universal coolant. Reply TesterJul '13 When possible always get rid of the Dexcool and use one of the universal antifreezes.

For what it’s worth, the 96 Camaro that my oldest son owns uses Dex Cool and that car went through 3 water pumps (counting the original) in about 4 or 5 years time not to mention the sludging problems. On the last pump replacement I flushed it out, replaced with green, and never a problem since. That’s going on 8 years now… Reply missilemanJul '13 I would never own a vehicle with Dex-Cool flowing through it’s engine. I always flush it out and replace it with the tried and true green stuff. Never had a problem in all the years I have done it. > [@Use Dex Cool in GM car or switch to universal during changeout?](https://community.cartalk.com/t/use-dex-cool-in-gm-car-or-switch-to-universal-during-changeout/80344/6): > > It doesn’t matter, but since you already have the universal, I would use it. DO NOT USE THE FLUSH chemical. Drain both the block and the radiator and then just refill with the new coolant with a mix of 2:1 antifreeze to distilled water. It will be good for another 5 years or so. Not just green stuff but global or universal is the important point. @common\_sense\_answer > [@Use Dex Cool in GM car or switch to universal during changeout?](https://community.cartalk.com/t/use-dex-cool-in-gm-car-or-switch-to-universal-during-changeout/80344/5): > > I would never own a vehicle with Dex-Cool flowing through it’s engine.

Of course it was 100k miles ago I switched to peak global, still waiting for an issue. --- _[View the full topic](https://community.cartalk.com/t/should-i-change-out-my-anti-freeze/108537)._
