What is your question?

The 96 Olds 88 has the 3.8L V-6 engine. One thing I am concerned about is coolant leakage problem. There was a class action suit involving the use of DexCool coolant in GM cars like this one. Coolant leakage can cause corrosion and problems with the intake manifold gasket in particular (both upper and lower). http://www.dslreports.com/forum/r19569981-GM-Dexcool-Intake-Manifold-lawsuit-settlement
