Thread: Pick Your Poison - Coolant Color?

Wow, this is pretty close between Green vs. Dex-Cool. I have a good amount of people telling me to ditch the Dex-Cool and run green, but then I have just as many telling me to keep the Dex-Cool because green is just as corrosive.

I know the HOAT coolant in my Jeep is supposed to be all famous for having powerful corrosion inhibitors (5yr coolant too), I've wondered if I could get away with running that stuff. The only drawback is that it's very very hard to find stuff.

At the end of the day I just really don't know what to do. Opinions seem split (closely at least) right down the middle.

Amen.

Dexcool is only a problem when air is introduced into the cooling system, or when you have a LIM gasket leak, etc. Dexcool is also the cause of the plastic LIM gasket failure.

From what I understand dexcool was reformulated a few years back (after the lawsuit) and is a different (better) animal now. So dexcool on the store shelves is the good stuff.

Switching coolant from dexcool to conventional is difficult because if you dont get every last drop of dexcool out of your system and install the green, you can turn you cooling system into jelly.


My vote is for dexcool, only because I am going to be running aluminum LIM gaskets.

Edit: Damn bio you beat me by a minute.
