Would it be a secret if I told you that your vehicle runs on heat? I doubt that. It does not matter what fuel is the one that your Jeep runs on, it is inevitably changed to heat so that the engine is running. However, it is essential that you understand one simple detail – it does not matter how heat-resistant the internal parts and fluids are – they can still overheat, and that will lead to damage. To prevent your engine from overheating, the cooling system was invented. However, a cooling system without coolant in it can do nothing.
That is where coolant fluids or antifreeze come in more than useful. Nevertheless, there are some issues to face here, too, since not all of them are identical and fit for all. Today I am going to share with you my opinion on the Best Coolant for Jeep Wrangler from Mopar, Zerex, and Peak. Hopefully, you will find the one that suits you most among them!

1. Mopar Antifreeze/Collant Fluid
1.1. Mopar Fluid 68048953AB for 1997-2012 Jeep Wrangler
If you are new to the auto universe, it may seem weird as to why there are so many different coolants on the market. However, you need to memorize one thing – it is never enough to come up with the coolant that you deem fit due to its functions. All the vehicles are created and sold with factory coolant, and it is essential that the one you get as the replacement coincides with the factory one 100%.
Mopar is a known brand that produces quality coolant/antifreeze fluid. It is an ethylene glycol-based coolant that fits the 5-year/100,000-mile formula. Of course, there are two main functions that the fluid is designed to carry out – cool down and prevent freeze-up. However, apart from that, the manufacturer decided that it would be helpful for the coolant to have an anti-corrosion effect too. It is designed for a variety of vehicles, including sport motorcycles, snowmobiles, and of course, off-road truck, the category that your Jeep Wrangler belongs too.
There are many ways to ensure that your engine stays the coolest possible when on the road. However, when it comes to extreme winters, the only way to ensure it does not freeze would be a reliable coolant at hand. Mopar is a proven brand on the Jeep coolant market. This exact variation is designed to be poured right in without the need of being diluted with water – those of you who are always on the go will appreciate the advantage.
Not only the coolant is highly and affordable, it is also lasting. The brand claims that once you get yourself a Mopar coolant, you won’t need to worry about a recent substitution since it is claimed to last as long as 150K miles, and that is impressive.
If you are looking for a quality product to protect your engine from overheating and from corrosion, the Mopar is the brand to trust.
2. Zerex G05 Phosphate Free Antifreeze
Some people are looking for items and parts that are only automaker-approved. Well, Zerex is one of such coolants that such auto giants as Ford, Mercedes, and Chrysler approve. This can only mean that it is a worthy investment into your Jeep Wrangler cooling system. Besides, when compared to other options available on the market, Zerex offers lower prices without any decrease in quality, that is a benefit to remember.
Zerex coolant is designed to fit both diesel as well as gasoline engines, and that widens the customer base, which is definitely great. The more people deem it worthy, the more reliable the brand proves to be. To add more, the coolant is designed to protect system metals from corrosion, and it also protects diesel engine cylinder liners from such a nasty thing as captivation. The defoamer system is created to be gentle and not damage hoses or any factory coatings and finishes.
In case auto brand approval matters to you, then Zerex is the coolant to consider. Apart from being well-approved, it is an affordable and quality product for your vehicle.
3. PEAK PXAB53 Antifreeze Coolant
Sometimes, the brand name speaks for itself – if you are looking for peak performance, then you should choose the given coolant. I am joking, of course, since there is a lot more to pay attention to rather than the name of the coolant brand. The Peak coolant, in its turn, is the coolant that has passed through all the certifications and is created according to the leading standards of the industry.
This is one of the coolant fluids that are created according to supreme organic technology. What does it give you? Well, to put it simply, it is designed to provide lifetime protection to the system. Patented inhibitors are the elements that are responsible for the rust protection of the system, and it is safe to say that they are strong enough to deal with the slightest chance of corrosion.
While the coolants mentioned above require to be distilled, the Peak coolant is ready to be used the minute you get it, so there is no need to add water.
The drivers who do not wish to deal with all the coolant dissolving – this is the coolant you need since Peak does not require any water to be added. If you are always in a rush, then this is the fluid you need.
