So why don't mine look like that? 20 years of service.
Why is this radiator clogged with the green stuff?
The old scuttle butt about Dexcool being junk is pure B/S. When it is used properly, like any other coolant with distilled or de-ionized water there is zero problems with it. (how many people use distilled)? All of your long life coolants today are almost identical to DexCool.
DexCool does not like air in the system and this
MAY be one of the causes of some of the problems that can occur.
DexCool is better for the aluminum components, hence why I run it. On a final note, I have seen recommendations that DexCool should be changed just as regularly as traditional green coolant. (every 2 years) Trying to run it for the advertised 5yr/150,000 time frame could also cause the stuff to gum up.
