2024 Jeep Grand Cherokee Coolant Capacity & Type

The 2024 Jeep Grand Cherokee typically holds between 13.0 and 14.0 quarts (12.3 to 13.2 liters) of coolant, depending on the specific engine configuration.

Quick Answer

• Total Cooling System Capacity: 13.0 - 14.0 quarts (12.3 - 13.2 liters)
• OEM Coolant Spec: Mopar Antifreeze/Coolant 10 Year/150,000 Mile Formula OAT (Organic Additive Technology). It is typically purple/pink in color and meets Chrysler Material Standard MS-90032.
• Mix Ratio: 50/50 prediluted or 50/50 concentrate mixed with distilled water.

Capacity by Engine Option

While specific capacities can vary slightly based on trim and features, the primary difference will be between the available powertrains.

Always consult your owner's manual for the precise capacity for your specific vehicle configuration.

Flush Interval

Maintaining your Grand Cherokee's cooling system according to the manufacturer's recommendations is crucial for longevity and performance.

• Normal Duty: Replace coolant every 10 years or 150,000 miles, whichever comes first.
• Severe Duty: If you frequently tow, drive in extreme temperatures, or operate in dusty conditions, it's advisable to inspect your coolant more frequently and consider replacing it earlier, perhaps around 5 years or 75,000 miles.

How to Refill & Bleed

Refilling and bleeding your Grand Cherokee's cooling system correctly is essential to prevent air pockets that can lead to overheating.

1. Safety First: Ensure the engine is completely cool before attempting any coolant system service. Wear appropriate safety glasses and gloves.
2. Drain Old Coolant: Locate and open the radiator draincock (petcock) at the bottom of the radiator. Place a drain pan underneath to catch the old coolant. For a complete flush, you may want to remove the lower radiator hose. Properly dispose of old coolant.
3. Flush (Optional but Recommended): If performing a full flush, close the draincock and fill the system with distilled water. Run the engine with the heater on high until it reaches operating temperature, then drain. Repeat until the water runs clear. Do NOT use tap water for the final fill.
4. Refill: Close the draincock. Slowly add the specified Mopar OAT coolant (50/50 mix) to the radiator filler neck. Fill the coolant reservoir to the "COLD FILL" line.
5. Bleed Air:
   • Leave the radiator cap off (or loosely placed) or reservoir cap open.
   • Start the engine and let it run until it reaches operating temperature, with the heater on high and fan on low. This opens the thermostat and allows coolant to circulate.
   • Occasionally rev the engine to about 2,500 RPM for 30 seconds, then release. This helps push air out.
   • Monitor the coolant level in the radiator and reservoir; add more as needed. You may see bubbles escaping.
   • On some Grand Cherokees, there may be a specific bleed screw on a hose or the thermostat housing. If present, open it carefully until a steady stream of coolant (without air bubbles) comes out, then close it.
   • Once the engine is at operating temperature and no more bubbles are visible, install the radiator cap. Check the reservoir level and adjust if necessary.
6. Final Check: After a test drive, allow the engine to cool completely and recheck the coolant level in the reservoir. Top off if needed.

Common Cooling System Issues (WK2/WL Generation)

Owners of the 2024 (WL generation) and previous (WK2 generation) Jeep Grand Cherokees may encounter some common cooling system issues:

• Water Pump Leaks: A common failure point. Look for coolant puddles under the front of the vehicle or a low coolant light.
• Radiator Leaks: Plastics end tanks can crack over time, leading to leaks. Road debris can also damage the radiator fins.
• Thermostat Housing Leaks: Often made of plastic, these can become brittle and crack, leading to coolant leaks, especially around the seal.
• Heater Core Issues: Can lead to a loss of heat inside the cabin, a sweet smell of coolant, or fogging windows from inside the car.
• Coolant Reservoir (Expansion Tank) Leaks: Over time, the plastic can develop cracks, often due to heat cycling.
• Electric Cooling Fan Failures: Reduces the airflow across the radiator, leading to overheating, especially at idle or in heavy traffic.

Regular inspection of hoses for swelling or cracks, checking for leaks, and maintaining the correct coolant type and level can help mitigate these issues.
