Also known as the antifreeze, the coolant is a liquid substance that helps to keep the engine “in check”. It’s equally capable of protecting it from overheating and freezing. When the engine is getting really hot, the Best Coolant for Jeep Wrangler absorbs most of that heat and gets rid of it by flowing back to the radiator. And when it’s a cold winter, it does the opposite – makes sure the engine is nice and warm.
In this post, you’ll find a list of the finest offers available on the market right now. They’re all reasonably-priced, easy to store and come from world-known brands. So, take your pick, and help the engine stay operational during the most extreme weather conditions!
1. Mopar Coolant
I want to point out right from the beginning that Mopar’s coolant is the most expensive one on the list. But, before you skip to the other two, let me just say that the price-tag is quite reasonable. First of all, this coolant is compatible with a long list of different trucks, SUVs, and even motorcycles. Secondly, it boasts enhanced resistance against harsh winters and summers.
Plus, the company offers different “configurations” to choose from. So, yes, even though the price is high, Mopar did an excellent job with this antifreeze and it will be money well spent.
Designed to withstand extremely cold/hot weather, the Mopar coolant is also highly flexible and versatile. It costs more than most similar products, though; so, if you’re on a tight budget, you might want to look elsewhere.
2. PEAK OET Extended Life Green
And here we have one of the most affordable coolants out there. PEAK made and tested it in the United States, which means you don’t have to worry about its quality. With this coolant, you’ll get top-of-the-line protection against scale and water deposits. These can cause the engine a lot of harm and even ruin it in the long run.
The only downside is the (minor) issues with quality control. Some customers complain about getting the wrong product or having it arrive with the seal broken. If this happens to you, don’t hesitate to contact PEAK for a replacement.
Looking for a cheap, yet decent-quality coolant for your Jeep Wrangler? Well, this could be exactly what you need! Made in the US, PEAK’s antifreeze is capable of both cooling and heating the engine. Plus, it protects against scale and water deposits.
3. Zerex G05 Antifreeze/Coolant
With the Zerex coolant, you can rest assured that the plastic parts or, say, the hose in the engine compartment, won’t be damaged. This is achieved thanks to the defoamer system. It’s also worth mentioning the unique European technology implemented into this product that protects all metals from rusting. A quick note: Zerex G05 can be used both with gasoline and diesel engines.
As for the cons, the formula is pretty much colorless. That means it will be harder for a new mechanic to figure out whether this is a 50/50 mix or just water. Other than that, this coolant is a bargain.
If not for the colorless origin of this coolant, it could’ve easily been the best pick. Regardless, the anti-rust protection, defoamer system, and compatibility with diesel and gasoline engines make it a safe bet.

Conclusion
And that is it for my list of the best coolant products on the market. As we learned today, they come in different shapes and sizes, but the formula is pretty much the same. PEAK offers one of the most affordable options out there. It is made and tested in the US and is quite effective at protecting against scale and (water) deposits. With Zerex, you’ll get protection against corrosion and rust, among other things.
As for Mopar’s coolant, it will be a good purchase for Wrangler owners living somewhere in Alaska or Arizona (places with extreme weather conditions). This isn’t the most affordable product, of course, but the price-tag is reasonable.
