I have a 1996 Olds 88 with 40k in mileage.
I am thinking about replacing the DexCool coolant in it. I've heard that this coolant causes a lot of problems with leakage and corrosion, particularly with the intake manifold.
Do you recommend that I flush the DexCool out?
Should I do a "power flush"?
And what coolant should I use instead of DexCool?
