    Default OT - What to replace Dexcool with in GM V8?

    First, I must confess... my wife indeed has a big ol' SUV. "Crash into me and I'll still come out unscathed" big Tahoe.

    It's time to get rid of the Dexcool... anyone know what to use in a 2002 GM V8 in place of Dexcool?

    TIA!

    I used the green stuff in the last DexaCool rebuilt I did....

    (Mixing DexaCool / Green because your bf told you it was ok isn't a good idea)
    New Headgasket, new value cover gasket, new water pump / term, new heater core, new rad, new hoses.... two knuckles... and the friend that said "Charles can do that sort of stuff" not helping a lot.... priceless + 500USD)

    Default Flush the whole thing well and repeatedly with one of the

    tap into the heater hose flush kits and a garden hose.. until you're positive you have all the dexcool out and then I would use the prestone extended life thats now green colored... 5 year life and supposedly compatible with the different coolants out there now, but i would still make every attempt to flush all the dexcool out first since it doesn't play well with others...
