    Only warning with Dex-cool is it has a very powerful smell that can make you a little sick when working with it for a couple hours.... But other that that its great and considered the best of all stock anti-freezes and if you have a leak its easy to see bright orange.

    I'm wondering if the NNBS Silverados and Sierras heater core are THAT much of a PITA to replace?

    Well there is more plastic and the dash is larger so idk, but more components would be snap fit no bolts.

    Core has been bypassed and truck will be in the shop on Monday to replace the core. Dexcool gunks up over time whereas the green does not. My Grand Prix had Dex and I had it flushed and it was nothing but gunk. Our van also has green.

    I have been using dexcool with distilled water since 1996 with no issues. changed coolant this summer on both my vehicles one being a 1996 with no coolant issues. dexcool works great . I do use dexcool GM approved coolant not a compatible type. with only distilled water .

    mixing of coolant types and using contaminated water like tap water and well water loaded with minerals and strong chemical sanitizers do cause big problems.

    if you can pull a gray color off the metal of the coolant system you have corrosion issues.
