Just top it off with a little distilled water and call it a day. It won't effect the overall %s much at all. The cooling systems holds 10.5 quarts (21 pints). Topping it off from min to max level isn't that much. If you want to add coolant, owner's manual says to use 50/50 mix.
Just straight coolant is ok also you are not going to effect your freeze protection to the wrong side of what your trying to achieve which is better cooling system freeze protection. I have worked in dealerships and small garages for almost 30 years and we never use distilled water to mix engine coolant which comes unmixed by the jug, we use plain tap water, 50/50 usually good for -35 to -40 degrees Fahrenheit. Distilled water is what we used to top up wet cell car batteries with back 15-20 years ago. Also if your level is down from full to add in your recovery/overflow container you probably have a small coolant leak some where. It is not normal for cooling systems to need top ups, unless you have had work done on the engine or cooling system and they did not fill it properly or it had air still in the system and now it has purged the air pockets and the level has dropped some. Top it up and monitor the level for a few days or week, if it goes down again you need to have it checked out.
The min. level is for a cold engine. If you add distilled water, 50/50 or straight HOAT that's fine. I prefer to top off using coolant. You're only adding a few ounces to the system. A factory fill is approx. 2-3" above the min. line on a cold engine unless the dealer added more prior to delivery. You should hardly ever have to top it off. If it seems like the level is going down you're probably loosing coolant. I've used straight HOAT to top off only once prior to flushing the system after 5 yrs. and it was only a couple of ounces. I then used pre-mixed Mopar 50/50 HOAT after the flush and I keep the level in the bottle like the factory fill.
Chrysler switched from HOAT to OAT sometime during 2013...ish. The changeover has caused all kinds of havoc because the colors of the two coolants can become indistinguishable. As RoadiJeff mentioned, 10-yr OAT SHOULD be purple; however, if you look at the graphic from this thread:
Since I have some extra time I was going to finish my CB radio install on my 16 JKU. I'm stuck on how to get power to it minus buying the Quadratec power adaptor. Plus I don't like the new site because searching for help has almost driven me to drink at 10AM. Thanks for the help!
