Hey Eric 2000 Gm should have dex cool Or death cool as I call it I see green coolant in then video Witch to me is just fine
even better Could not find part 2 but you need to mention jf there was dex cool and you use the old time green stuff
you need to totally flush the orange crap out. YOU CAN NOT mix dex cool and the green stuff as
it will became a major disaster
Me personally I like the old time green antifreeze Dex cool has caused so many problems and today GM still refuse to admit that it is any good My jeep uses a coolant called hoat a little pricey but it does not have the problems that comes with dex cool
pont trying to make is make sure what type of coolant your vehicle takes using the wrong coolant can cause intake gas-kits to leak along with head gaskets and over heating and sludging up your whole coolant system
