What year TJ's use the Zerex G05 Coolant? I saw 2 types of Zerex G05 coolant regular and the 50/50 mix which of the two should I get?
X2, agreed. And no need to pay more than what Zerex G-05 costs, it is a superb coolant.Never buy 50/50. Unless you can get it for less then 1/2 the price of full strength. You are literally paying for 50% water. I go down to the Walmart or any grocery store and buy "distilled" water. The same kind that you use in your iron. You can get a gallon of water for less than a dollar. So the 1 gallon of antifreeze becomes 2. I save an old 1 gallon bottle of anything(clean)and mix it up.
This will also come in handy to keep in the jeep.
GM is associated with Dexcool which is notorious for causing cooling system problems. Many consider Dexcool to be the work of the devil since if it's not changed often enough, it turns into Dexsludge. GM was sued at one point over its Dexcool coolant.This last weekend was my first exposure to the Zerex coolant. Is that required for the TJ cooling system, or just vastly superior and preferred to regular anti-freeze? Because of their construction, I know that some GM and Pontiacs have to have a special coolant, but until this weekend, I wasn't sure if the same went for Jeeps. Judging by the labeling on it, it actually covers several different late-model makes (Ford, etc).
I'd heard the same things about it, too. However, as a disclaimer, my wheels before the Jeep were a 2003 Pontiac Sunfire, which is basically just a two-door coupe version of the Chevy Cavalier, and I never had any issue with DEX-COOL. However, I did only have it for a couple of years, and never flushed it.GM is associated with Dexcool which is notorious for causing cooling system problems.

Nearly any coolant can be used but propylene-glycol based coolants should be avoided as they provide less freeze protection and less corrosion protection. HOAT Is what the factory switched to as it's simply a better and more protective coolant. That's why Jeep switched to it. We consistently recommend Zerex G-05 because it's a HOAT that is known to work extremely well. I also use Zerex G-05 as it is also compatible with my daily driver BMW and my wife's Lexus.
