My coolant overflow tank in '02 JGC 4.7L has been surprisingly low and I need to add some antifreeze/distilled water mix but... I see all this talk about HOAT coolants that DC uses so what's in there OEM? Do I need to go to Jeep for the HOAT coolant or can I just use whatever Autozone has?

I use whatever Atozone, Napa ETC. has. Really havnt noticed a difference in two at all.

I know this sounds dumb but: make sure you buy the right color! :mrgreen: Seriously though, they say that if you mix the red type coolant and the greenish yellow type coolant together, they make a nasty sludge in your radiator. I personally would be on the safe side and get the OEM stuff (doesn't yours run the "long life" type?). I dunno, I guess I'm paranoid but, some things I think when in doubt go OEM! :lol:

Im with you on that one. Ive heard that also and actually had one of my friends over in my shop to swap his radiator for a performance one in a Nissan Skyliner GTR and he mixed his up and we emptied his old radiator sludge came out with it. Dont know for sure thats what it was.
