Hello, I have a 1999 Camaro with the V6 3800 series II 3.8 engine. It's a great engine, but I heard that there is some plastic part that needs to be replaced because Dexcool coupled with the plastic eats it and and there is a coolant leak.
What is the exact part and name that needs to be replaced: is the intake manifold or is it called upper lower, or what?
