I recently (a couple of months ago) replaced some hoses with silicone versions in an engine that uses dexcool. Now I'm learning that's a bad thing - the dex has 2-eha that will eat the silicone? Does this apply to any type of silicone hose? The hose I used has two layers, the inner is red, the outer is blue, if that means anything. I guess I'll need to flush the coolant and pick a non-2-eha type?
