Re: Controversial: Where is the evidence that DexCool has no part in HG woes?
When these were really catching among large manufacterers in the '90's, there was usually a good 15% increase in performance and economy from the plastic manifold alone.
On the Dex note, GM was increasingly notorious for intake manifold leaks as soon as they started using aluminum intake manifolds - WELL before the introduction of Dex.
