2023 Jeep Cherokee Coolant Capacity & Type

The 2023 Jeep Cherokee cooling system holds approximately 10.0 quarts (9.5 liters) of coolant.

Quick Answer

• Total Cooling System Capacity: Approximately 10.0 quarts (9.5 liters)
• OEM Coolant Spec: Mopar Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT (Organic Additive Technology), Purple in color. Meets Chrysler Material Standard MS-12106.
• Mix Ratio: 50/50 prediluted or 50/50 mix of concentrate with distilled water.

Capacity by Engine Option

For the 2023 Jeep Cherokee, the coolant capacity remains consistent regardless of the engine option. Both the 2.4L Tigershark MultiAir 2 and the 3.2L Pentastar V6 engines utilize a cooling system with a total capacity of around 10.0 quarts (9.5 liters).

Flush Interval

• Normal Duty: The manufacturer recommends replacing the coolant every 10 years or 150,000 miles, whichever comes first, when using the specified OAT coolant (Mopar MS-12106).
• Severe Duty: If your driving conditions are considered severe (e.g., frequent towing, extreme temperatures, dusty environments, or heavy-duty commercial use), it is advisable to inspect your coolant more frequently and consider replacing it every 5 years or 75,000 miles.

How to Refill & Bleed

Properly refilling and bleeding the cooling system is crucial to prevent air pockets, which can lead to overheating. Here's a general procedure for the 2023 Jeep Cherokee:

1. Preparation: Ensure the engine is cool. Position the vehicle on a level surface. Wear appropriate safety gear (gloves, eye protection).
2. Drain (if flushing): Open the radiator drain cock (petcock) located at the bottom of the radiator to drain the old coolant into a suitable container. Don't forget to open the radiator cap to speed up draining. If replacing, drain the overflow reservoir as well.
3. Flush (if necessary): If flushing, close the drain cock, fill with distilled water, run the engine with the heater on until warm, then drain. Repeat until the drained water is clear. You can use a cooling system flush product if desired, following its instructions.
4. Refill: Close the radiator drain cock. Slowly add the correct 50/50 OAT coolant mixture to the radiator until it's full. Fill the coolant reservoir to the "COLD FILL" line.
5. Bleeding Procedure:
   • Start the engine and let it idle with the heater fan on high and the temperature set to maximum heat. This helps open the heater core valve and circulate coolant.
   • As the engine warms up, coolant level in the radiator and reservoir may drop as air pockets escape. Keep topping up the radiator and reservoir with coolant as needed.
   • Look for a bleeder screw or valve on the thermostat housing or radiator hose, if present. Opening this slightly can help release trapped air. (Consult your owner's manual or a service manual for the exact location, if any.) The 2023 Jeep Cherokee cooling system is generally self-bleeding, but vigilance is key.
   • Squeeze the upper and lower radiator hoses several times to help dislodge air bubbles.
   • Continue to monitor the coolant level in the reservoir and top up as necessary until the engine reaches normal operating temperature and the fan cycles on and off a few times. You should see a steady flow of coolant in the radiator neck (with the cap off).
6. Final Check: Install the radiator cap and reservoir cap. Take the vehicle for a short drive, then allow it to cool down. Recheck the coolant level in the reservoir and top off if needed.

Common Cooling System Issues

For the generation of Jeep Cherokee that includes the 2023 model, several common cooling system issues have been reported or are good to be aware of:

• Thermostat Housing Leaks: The plastic thermostat housing can be prone to cracking or developing leaks, leading to coolant loss. This is a fairly common issue on many modern vehicles with plastic components in the cooling system.
• Water Pump Failures: While not exclusive to the Cherokee, water pump failures (often manifesting as leaks or noise) can occur, especially as the vehicle ages or accumulates mileage.
• Radiator Leaks: Radiators can develop leaks over time due to wear, road debris, or fatigue of plastic end tanks (if applicable).
• Coolant System Hose Leaks: Hoses can degrade, crack, or become brittle with age and temperature fluctuations, leading to leaks.
• Head Gasket Issues (less common but possible with severe overheating): While modern head gaskets are robust, severe or prolonged overheating due to unaddressed cooling system issues can eventually lead to head gasket failure.
• Electric Cooling Fan Problems: Malfunctioning cooling fans can lead to overheating, especially in stop-and-go traffic or at low speeds. Issues can range from a bad motor to faulty relays or wiring.

Always use the specified Mopar OAT coolant (MS-12106) and distilled water to prevent compatibility issues and premature wear of cooling system components.
