Hi Gang - Regarding 2004 4.0 Wrangler Automatic

I realize this topic has been discussed previously. My deepest apologies: Having difficulty/confusion with Advance and Auto Zone who claim Prestone 'All Vehicle' is acceptable? However additional research shows Prestone AF2000 (2nd one below) is the preferred Mopar Equivalent?

Unfortunately I've already installed the 'All Vehicles' type but did not drive more than 2 miles. So I'm prepared to do yet another flush and use either Mopar (if I can find it), or the 2nd Prestone type (above)? I've also read that HOAT and OAT are not compatible with each other? To summarize, can someone tell me if Prestone AF2000 is the preferred- acceptable Mopar Equivalent?

Sorry for the confusion 🙄
Thank You for your help :)

For your TJ, just make sure that it is a HOAT Antifreeze.

Hi There Dogger - Thanks for the reply. I've had Jeeps for 25 years and there always seems to be a dabate about what coolant to use? The older coolant had a Red/Orange color. I couldn't find the same coolant I used 5 years ago? Soooo, first I flushed out the system, installed new thermostat, hoses and radiator, and installed Prestone 'All Vehicles' which has a Green Color. The Prestone label (on the back) says: Compatible with HOAT, OAT, POAT, & IAT

BUT

Some guys say that Prestone Coolant 'All Vehicles' is 'No Good'? Is Prestone AF2000 considered the 'preferred' Mopar Equivalent?

I'm prepared to do another flush, and switch to something else (if I could find it locally)?

Thank you ....

No experience with the all vehicle stuff, but mixing is usually a bad idea.

Zerex G05 is HOAT and easy to find. It's what I've used in my 06 after flushing the OEM.

With that said, my 92 came with the standard green antifreeze of that period and it's been fine.

Being that HOAT and Oat are not compatible, it would be of a concern that this antifreeze could be used with either or. If it was mine, I would re-flush it and purchase a known HOAT Antifreeze like Zerox, or Mopar HOAT. Then you will know what you have, and not cause a possible issue. The color doesn’t matter, what does is that it is HOAT.

If you flushed it all out and only had water left in the system, you're not mixing coolants.

The only preferred coolant is a HOAT as stated above, as that's what the manufacturer spec'd.

"Zerox, or Mopar HOAT"

That's FINE by me but no one around here carries Mopar

Can someone recommend something that Advance, or Auto Zone carry? I'd like to get it now, can't wait for a mail order ....

Maybe I'll try NAPA?
