2022 Jeep Cherokee Coolant Capacity & Type

The 2022 Jeep Cherokee holds between 7.1 and 9.7 quarts (6.7 to 9.2 liters) of coolant, depending on which engine your vehicle is equipped with. Keeping your Cherokee’s cooling system maintained with the exact factory-specified fluid is critical to preventing overheating, premature water pump wear, and heater core blockages.

As an ASE-certified master technician, I always emphasize using the correct chemistry for modern FCA (Stellantis) vehicles, as mixing the wrong fluids can cause catastrophic gelling in the system.

Quick Answer

Here are the essential cooling system specifications for the 2022 Jeep Cherokee:

• Total Cooling System Capacity: 7.1 to 9.7 quarts (6.7L – 9.2L) depending on the engine.
• OEM Coolant Specification: Mopar 10-Year/150,000 Mile Formula OAT (Organic Additive Technology). The official manufacturer spec number is MS-12106.
• Coolant Color: Purple. (Note: Never mix this with older orange or green coolants).
• Mix Ratio: 50/50 mixture of OAT concentrate and distilled water, or a pre-diluted 50/50 premix.

Capacity by Engine Option

The 2022 Jeep Cherokee was offered with three different engine options. Make sure to reference your specific powertrain when purchasing coolant:

Note: Capacities are approximate and include the heater core and coolant recovery bottle. Always buy an extra quart to top off after bleeding the system.

Flush Interval

Stellantis (Jeep) utilizes a long-life OAT coolant in the 2022 Cherokee, which boasts a very respectable lifespan. However, how you drive dictates when you should service it.

• Normal Duty: Flush and replace the coolant every 10 years or 150,000 miles, whichever comes first.
• Severe Duty: If you frequently tow, idle for extended periods, or drive in extreme heat or dusty conditions, consider flushing the system every 5 years or 100,000 miles to ensure peak corrosion protection.

How to Refill & Bleed

Modern Jeep cooling systems are notorious for trapping air, which can lead to overheating and a lack of heat in the cabin. Here is the best practice for refilling and bleeding the 2022 Cherokee:

1. Prep: Ensure the engine is completely cold. Locate the coolant pressure bottle.
2. Vacuum Fill (Highly Recommended): The absolute best way to fill these engines (especially the 3.2L V6 and 2.0L Turbo) is by using a vacuum coolant refill tool. This pulls a vacuum on the empty system, removing all air, and draws the new coolant in perfectly without leaving air pockets.
3. Manual Bleed (If vacuum tool is unavailable): Fill the coolant reservoir to the "MAX" line.
4. Use the Bleeder: If your specific engine has a bleeder valve on the thermostat housing (common on the V6), open it slightly while filling until a steady stream of fluid comes out, then close it tight.
5. Burp the System: Leave the reservoir cap off, start the engine, and turn the cabin heater to the highest temperature with low fan speed. Let the engine idle until it reaches operating temperature and the radiator fan turns on.
6. Top Off: As the thermostat opens, the coolant level will drop. Add 50/50 Mopar coolant as needed. Once the level stabilizes, replace the cap and test drive. Recheck the cold level the next morning.

Common Cooling System Issues

For this generation of the Jeep Cherokee (KL platform), keep an eye out for the following cooling system issues:

• Thermostat Housing Leaks (3.2L V6): The plastic thermostat housings on the Pentastar engines are prone to warping and cracking over time, leading to slow coolant leaks in the engine valley.
• Water Pump Seepage: High-mileage Cherokees may develop weeping around the water pump seal. If you smell sweet coolant but don't see a puddle, check the weep hole on the water pump.
• Radiator Seam Failure: The crimped plastic end tanks on the radiator can separate from the aluminum core, usually triggered by pressure spikes or age.
