hi i just had the radiator coolant changed it was black i have a 3.4 it doesnt overheat or anything but i changed also the low coolant light is on but i check it it is at the right level but black again it uses dex-cool i dont know what to do because if its something big i have no money to fix should i just run it till it dies or is this normal for dex-cool??
