What Type Of Coolant Does A Jeep Wrangler Take?

Check the table below for the type of coolant a Jeep Wrangler takes:

Coolant TypeCoolant ColorCoolant NameJeep Wrangler Model
IATGreenZEREX™ Original GreenBest for vintage or older automobiles. Not suggested for use in Jeeps.
OATYellow, orange, purple, red, and even blue.MOPAR 68163848AB Antifreeze CoolantMost suitable for Jeep models from 2013 and after.
HOATPink, blue, purple, and turquoise.MOPAR HOAT Antifreeze 68048953ABMost suitable for Jeep versions from 2012 and earlier.

Inorganic Additive Technology (IAT)

IAT is regarded as an antiquated coolant. It can deteriorate cooling systems and result in heater core blockages if not changed after two years. However, using IAT coolant in any Jeep vehicle is not advised by Jeep.

Organic Acid Technology (OAT)

It serves as a more contemporary, effective coolant. The 2017 Jeep Wrangler requires OAT.  This coolant’s corrosion inhibitors function more slowly but last longer. It is advised to cleanse it out after ten years or 135,000 miles since it may erode on some metallic materials.

Hybrid Organic Acid Technology (HOAT)

Combining IAT and OAT coolant types is known as HOAT. The lifespan of this coolant is up to five years, or 150,000 kilometers. Till 2012, it had been the kind that was advised for Jeeps.

How To Know If Your Jeep Wrangler Requires A Coolant Change?

Maintaining fresh coolant with factory-recommended coolant changes is crucial. The following are typical signs that your Jeep Wrangler needs a coolant flush:

  • The engine may make strange crushing sounds.
  • When the engine is operating, coolant frequently leaks out. Before you stop, verify the surface.
  • The Jeep heater can break down.
  • Perhaps the check engine light will come on.
  • Steam will emerge from the bonnet or radiator.
  • You may occasionally smell a strange burnt smell from underneath the hood.
  • With the engine running for a while, the temperature reading will register well over usual.
  • You may notice corrosion or sediment buildup in the antifreeze. 

How To Change Jeep Wrangler 2017 Coolant?

Typically, you should cleanse the 2017 Jeep Wrangler coolant out after ten years or 135,000 miles. Changing it yourself is a reasonable option. You can take the following actions:

Step 1: Park The Jeep

Place your Jeep in a level parking space. Pick a solid surface and set up some rags there. A cool engine is a must. Give the engine enough time to cool down before starting.

Step 2: Elevate The Jeep

You have to elevate the Jeep. You’ll require sufficient space under it to move around freely. For your convenience, ensure the jack is fastened in all necessary places.

Step 3: Open The Drain Valve

Place the radiator drain pan underneath the valve. You can use a screwdriver or your hand to unlock the drain valve. Some automobiles may include a drain cock. If necessary, take it away first. However, make sure to put it somewhere so you will retain it.

Step 4: Drain The Coolant

Be sure to let all the coolant drain. As long as any remaining antifreeze is present, it will keep flowing. Put the used coolant in a waste container.

Step 5: Close The Drain Valve

Firmly close the drain valve. The coolant will overflow if it is not secured tightly yet. It would be best if you now flushed your radiators.

Step 6: Put The Coolant

Carefully pour in your coolant. If you decide to apply a more potent formula, you must dilute it by combining it with water.


Things To Consider While Picking Coolant for Jeep Wrangler 2017

You must ensure that the coolant you use is appropriate. If you choose the incorrect coolant, your Jeep’s functionality will gradually decline. 

The choice of coolant for your car is actually quite crucial. When choosing coolant, keep the following things in mind:


The type of coolant plays a significant role based on the kind and age of your engine. Using the incorrect coolant might result in some issues. Using the maintenance manual for your Jeep, you can determine the type of coolant needed for your generation and engine variety.


A concentrated recipe must be diluted with a mixture of 50% solution and 50% water. You needn’t dilute the pre-mixed coolant with water if you get it.

Manufacturer’s Recommendation

Never alter the type of coolant your car was initially built with. A particular kind of coolant was designed to work with specific engines. Therefore, it is usually better to follow the manufacturer’s advice.

Result Of Using The Wrong Coolant in Jeep Wrangler 2017

The function of the engine can be hampered by using the incorrect coolant. This might cause the radiator to corrode more quickly. The cooling system’s protecting layers eventually get more porous and thin. As a result, changing the engine coolant more frequently is crucial.

Corrosion can result from combining or applying a coolant not suggested for a Jeep. It will harm the engine and other parts of the vehicle. In the worst situation, this may result in engine failure.

It’s essential to keep in mind that color alone cannot accurately describe the type of coolant you should use. The best way to ensure that you get the appropriate coolant is to have a trained auto repairer manage your Jeep’s maintenance.
