The discussions about DEX-Cool with 2-EHA that is a known "plasticizer" and eats away intake gaskets have been very confusing to me.
The car has a plastic radiator cap, plastic reservoir tank, plastic parts on the radiator, plastic parts on the heater core, and dex-cool comes in a plastic jug, but none of these are leaking due to dex-cool.
Why is the plastic container of dex-cool not leaking ?
The reason is because Dex-cool 2-EHA is only a "plasticizer" to a specific type of plastic that was used on gaskets.
