Wasn't sure what to do earlier today. I Googled. I Naxja'd. I checked all over online. I hadn'r seen any replies yet while standing at parts store. Oreilly's, Advance, nor Auto zone could tell me. I did read that Zerex G05 met standards and had HOAT. Being I was unsure of others and Zerex was the only one that specifically said Chrysler and Jeep on it, I went for it. So not green, not orange, but actually clear.
Now I just hope I flushed it good enough. I flushed it twice for about 8-10 minutes each. One time I specifically flushed the heater core both directions.
I went from No Heat at all to having very hot heat now. This happened once before but heat only lasted a day. However, I didn't do this thorough of a flush last time so we'll see how it goes this time.
My 01 came with Green and that's what I use. As others have said you can use G05 etc as long as you do the proper flush first. Be advised that Zerex is the Valvoline trade name for their coolant you can get it Conventional Green, G05, etc.... my local farm store sells Zerex Conventional Green as an example.
