How much coolant does a 2012 Dodge Durango hold?
The cooling capacity of a 2012 Dodge Durango depends on the engine. In general, the Durango’s cooling system holds about 11 quarts (roughly 10.5 liters) for the 3.6L V6 and about 14–15 quarts (roughly 13.3–14.2 liters) for the 5.7L Hemi V8.
Understanding the exact capacity matters for proper servicing, including draining, refilling, and bleeding air from the cooling system. The figures below reflect typical factory specifications for the stock cooling system, including the radiator, heater core, engine block passages, hoses, thermostat housing, and overflow reservoir. Variations can occur based on model specifics, options, or service history.
Engine options in the 2012 Durango
In 2012, the Durango offered multiple engines. The coolant capacity changes with engine size because a larger engine generally requires a larger cooling circuit. The following breakdown highlights typical factory estimates for each engine.
3.6L Pentastar V6
The 3.6L Pentastar option has a smaller cooling loop, typically around 11 quarts (approximately 10.5 liters) of coolant in the full system.
- Total cooling-system capacity: about 11 quarts (10.5 L)
- Includes radiator, heater core, engine block passages, hoses, and thermostat housing
Note: Exact capacity can vary slightly by production year, radiator configuration, or installed options.
5.7L Hemi V8
The 5.7L Hemi requires a larger cooling loop to manage higher heat output, typically about 14–15 quarts (approximately 13.3–14.2 liters).
- Total cooling-system capacity: about 14–15 quarts (13.3–14.2 L)
- Includes radiator, heater core, engine block passages, hoses, and thermostat housing
As with the smaller engine, exact numbers can vary slightly depending on equipment, configuration, and service history.
Why coolant capacity matters
Accurate coolant capacity is essential for proper maintenance. Overfilling can cause excess pressure, while underfilling can lead to overheating and potential damage. When changing coolant, drain the system completely, refill with the correct total capacity, and bleed the cooling system as specified in the service manual to remove trapped air.
Summary
For the 2012 Dodge Durango, coolant capacity is engine-dependent: about 11 quarts (10.5 L) for the 3.6L V6 and about 14–15 quarts (13.3–14.2 L) for the 5.7L Hemi. Always confirm the exact figures in your vehicle’s manual or service documentation and follow proper bleeding procedures during a coolant change.
