The Mopar stuff will set you back about $25 a gallon. Get the NAPA stuff and be happy.

Also, it comes 50/50 or full strength, so the prices vary.

Zerex G-05 is the same as the MOPAR stuff.

Just a side note. If you do mix your own, use distilled water.

Any G-05 will do. Is it hard to find in your area?
Yes!! Only place is the dealer. And if you got to the parts store they try to sell you regular 50/50 prestone

Cheers
**Update** The source of the leak ended up being a bad coolant intake gasket. After replacing that and refilling the coolant, no more leaks and lava hot heat!!

Is it tremendously important to use distilled water for the 50/50 part?

Just buy the premixed kind and be done with it.

Yes. You want water with no chemicals or minerals in it.

If you use tap water the minerals and crap will collect in the system. The smallest passages are in the radiator, so that's where most of it will collect, clogging it. It's not the end of the world if you topped it off, but don't make it a habit because eventually it'll come back and bite you in the form of an overheating engine and most likely a new radiator. Either buy the 50/50 premixed or mix it yourself with distilled water...I haven't actually compared the prices to see which is cheaper.

Water actually does the cooling, not antifreeze...that's just a chemical to assist in heat transfer and to raise the boiling point and lower the freezing point.

Absolutely correct. 2013s use a new and differently formulated OAT.

Not the HOAT of the 2007-1012s JKs and not the OAT of older formulas.

Be aware!
