Post 2011 Antifreeze top up (what type to use?)

I am wondering if someone can advise if there is any reason we MUST use Mopar antifreeze instead of the conventional options you find at various autoparts shops? I have read on another thread in this forum that the autoparts shops' varieties are just fine, but then I read on yet another thread where someone suggested that using non-Mopar may be the cause of some other issues they encountered (and others chimed in agreeing and saying to spend the extra $ for Mopar).

Is the 3.6L really that advanced of an engine that it needs to have the 'secret recipe' that Mopar has concocted? I know there are different ratings (just as there is with engine oil, etc), so my thinking is as long as it meets a preferred rating level, then I should be fine. I am past warranty, so from that perspective, I am not concerned. Biggest worry for me is to be found on side of road with hood up. This has been a perfectly reliable vehicle to date and I dont want to tempt fate... yet, I also don't want to continue to support the stupid inflated prices the dealership charges for their Mopar brand products if there truly is the ability to interchange with other reliable products on the market. If it matters, I do not plan to drain the system. I am intending to top up, so this would mean adding (at say a 50/50 mixture) to the current factory fluid.

Owners Manuals says the following:
Engine Coolant MOPAR Antifreeze/Coolant 5 Year/100,000 Mile Formula HOAT (Hybrid Organic Additive Technology) or equivalent.

I agree, major pain to pay for OEM stuff, but....
I used to have the same caveat with my Audi.
There was just nothing in the aftermarket that really was equivalent and if you used something else you ran the risk of corrosion/leaks because of the all aluminum engine block and the various pieces that bolt up to it (galvanic corrosion issues).

A gallon of OEM stuff should last for quite some time unless you have a leak, in which case it would be in your best interest to find/fix the leak.

Re: 2011 Antifreeze top up (what type to use?)

HOAT coolant is somewhat special, yes. If you are just "topping up" the system then stick with the OEM stuff. Theoretically, any HOAT coolant can be mixed but there is no proof and a lot of rumor. Unlike oil which is required to be mixable across brand.
That out of the way, if you are doing a flush and fill as required every 5 years then any HOAT coolant will suffice. Zerex is approved for use in Daimler Chrysler if you need that stamp of approval. If you don't then Prestone and Pentosin make one as well. Of course, cost is a factor. Economically speaking it is cheaper to go with the OEM stuff. I got it at my dealer for $26/ gal. The other brands I mentioned are $30-$35/ gal! Remember, the MOPAR is not diluted. One gallon makes 2 gallons of coolant. The others are already diluted with water.
Hmmm.... so if they are half water, is it $30/gal for antifreeze or $30/ gal for water?!?

Actually Mopar sells a 50/50 blended HOAT antifreeze, non-concentrated. I picked it up a couple of months ago after I saw I was getting low on coolant. I think it cost me about $24.

Please keep in mind, depending on the year of your model GC, it will use a different antifreeze. 2011 - 2012 uses i believe he orange liquid, while 2013 and above uses the purple.

Good info!
Guess I got lucky and didn't buy the expensive water one.

It may have changed during the model year 2013 as my 2013 JGC V8 has the orange colored fluid???

Yes, I check my reservoir in my 2015 Hemi and the OAT coolant looks to me that it is Orange, not the Purple they were using. will double check with my pal at the dealership who is a Tech.
