Jeep Wrangler OAT Coolant: All You Need To Know

A Coolant is a substance used to control the temperature of an automobile. Most fluid coolants are a combination of ethylene glycol and water. Both of these share a concentration of 50% each.

The ethylene glycol decreases the boiling point, and the water helps conduct the heat. This substance is exceptionally vital in the cooler regions of the world.

Coolants created using Organic Acid Technology (OAT) last approximately twice as long as earlier coolants and are environmentally friendly. The lifetime of the Jeep Wrangler OAT coolant may be as long as five years or up to a staggering 150,000 miles in certain situations.

You must do proper research before buying or replacing antifreeze in your car because not all vehicles will behave the same with every type of coolant.

However, the performance of those vehicles will be mostly the same, even with generic coolants. So, be careful which product you choose for your Jeep Wrangler.

What Are The Signs Of Low Coolant In Jeep Wranglers?

To be honest, it’s not necessary for a Jeep Wrangler to entirely run out of antifreeze for various problems to initiate.

Instead, the concentration levels have to be within a significant level. Otherwise, the Jeep Wrangler machine parts may begin to deteriorate or become irreversibly damaged.

On the other hand, if you completely run out of coolant due to leakage or low fluid supplies, the entire engine unit might get damaged.

Symptoms of Low Coolant

The following are some of the most common signs that a Jeep Wrangler is low on coolant:

  • The radiator will produce steam.
  • It is possible that the check engine warning light would turn on.
  • Coolant will continually seep out of the engines while it is in operation.
  • The machine might make strange grinding sounds.
  • You might detect a burning stench originating from beneath the hood.
  • A rusty or sedimented antifreeze will be noticeable.
  • With the engine running for an extended period, the temperature reading will rise much over the permitted level.

What Color Coolant Does Jeep Wrangler Use?

Nowadays, there are so many varieties of refrigerants available for you to choose from. Strangely though, back till the 1990s, there had been essentially just one kind of coolant available.

Even though that vintage green compound coolant had corrosion protection, it only lasted around 30,000 miles on average. If you do the calculation accurately, it means that it lasted for nearly three years.

So, you must recognize that color doesn’t quite mean a thing in this situation. Most OAT coolants are typically red, yellow, orange, or purple.

There is also Inorganic Acid Technology (IAT) coolants, which are typically green in color, though some companies manufacture them in blue. However, Hybrid Organic Acid Technology (HOAT) refrigerants are primarily yellow and orange.

That’s why these should be easily identifiable by their color. Nonetheless, you can always check the packaging for further details.

How To Add OAT Coolant In Jeep Wrangler?

Even if somebody’s not a professional technician, changing the coolant of a Jeep Wrangler is a reasonable alternative for most people.

The option of replacing it yourself is an excellent choice if you are familiar with your car and have all the essential tools on hand. The fundamental procedures are as follows:

Step-01: Refill the radiator with concentrated antifreeze while the drain is closed as tight as possible.

Step-02: Close the top of the expansion tank after adding an appropriate amount of coolant.

Step-03: Before putting on the top cap, ensure the engine is running and that the radiator has enough antifreeze.

Step-04: Allow the vehicle to heat up for approximately ten minutes before attempting to turn the thermostat on.

Step-05: Ensure no coolant leaks when the vehicle is operating.

Step-06: Finally, get rid of the old coolant and dispose of it properly.

Benefits Of Using OAT Coolant Jeep Wrangler?

Improved engine safety and superior coolant efficiency throughout its service life are the two key advantages of using OAT coolants in the engine.

Remove Pollutants From the Environment

OAT coolants remove pollutants that inhibit heat transmission from the metallic components to the fluid. These pollutants serve as an insulation substance and obstruct the coolant’s job.

Improve Thermal Efficiency

This product offers impressive total thermal efficiency by ensuring proper sustainable heat exchange for extended periods. This then drastically improves the overall performance of the Jeep Wrangler.

Increase Operation Life

Another key advantage is the increased operational life of these traditional coolants. Earlier coolants usually had usable energy that can reach up to 2,000 hours which is approximately two years.

However, heavy machinery OAT coolants commonly reach or surpass 4,000 to 6,000 hours – that’s around 4-6 years depending upon the quality of maintenance. Engine coolants are less wasteful and easier to recycle with a longer lifespan.

What Happens If You Put Wrong Coolant In Your Jeep Wrangler?

Different varieties of engine coolants should not be mixed. Also, the inappropriate coolant might hinder the operation of the specific additive packages, leading to greater corrosion of the main components and other parts of the engine.

An engine coolant must be renewed more often as the safety layers in the cooling system grow thinner by the day and become leakier. As a result, the coolant must be replaced frequently.

Using the incorrect coolant may cause damage and harm to the fuel pump, radiator, and other major components over time. It can even affect the engine’s overall performance, which will cause you to replace the entire machine.


Coolants have evolved throughout time, making the choosing procedure more difficult than before.

However, understanding the distinctions between them and identifying the best Jeep Wrangler OAT coolants is critical in making the ultimate selection.

But do remember that the proper maintenance of your vehicle, as well as maintaining the fluid levels at the appropriate levels, can assist in ensuring that your Jeep operates at the ideal temperature.

And so make sure you maintain that and keep your Jeep Wrangler as healthy as it can be!
