2017 Ram 1500 Coolant Capacity & Type

The 2017 Ram 1500 coolant system typically holds between 14.2 to 15.5 quarts (13.4 to 14.7 liters) of coolant, though this can vary slightly by engine. Maintaining the correct coolant type and level is crucial for the longevity and performance of your truck's engine.

Quick Answer

• Total Cooling System Capacity: 14.2 - 15.5 quarts (13.4 - 14.7 liters)
• OEM Coolant Spec: Mopar Antifreeze/Coolant 10 Year/150,000 Mile (Purple in color, OAT - Organic Additive Technology, Mopar MS-90032, or equivalent such as Mopar MS-12106 coolant)
• Mix Ratio: 50/50 Pre-mix (or 50% concentrate with 50% distilled water)

Capacity by Engine Option

The 2017 Ram 1500 was offered with several engine options, and each may have a slightly different cooling system capacity. It's always best to check your owner's manual for the most accurate information specific to your vehicle's configuration.

• 3.6L Pentastar V6: Approximately 14.2 quarts (13.4 liters)
• 5.7L HEMI V8: Approximately 15.0 quarts (14.2 liters)
• 3.0L EcoDiesel V6: Approximately 15.5 quarts (14.7 liters)

Flush Interval

Regular coolant flushes are essential to remove contaminants and replenish the corrosion inhibitors in your cooling system. Following the manufacturer's recommended maintenance schedule will help prevent costly repairs down the line.

• Normal Duty: Typically, 10 years or 150,000 miles, whichever comes first.
• Severe Duty: If you frequently tow, haul heavy loads, drive in extreme temperatures, or operate in dusty conditions, it's wise to consider flushing the coolant more frequently, potentially every 5 years or 75,000 miles.

How to Refill & Bleed

Properly refilling and bleeding the cooling system after a drain or flush is critical to prevent air pockets, which can lead to overheating. Always perform these steps on a cool engine.

Steps:

1. Drain: With the engine cool, place a drain pan under the radiator. Open the radiator drain cock and remove the radiator cap to allow the system to drain completely.
2. Flush (Optional but Recommended): If performing a flush, close the drain cock and fill the system with distilled water. Run the engine with the heater on high until it reaches operating temperature, then cool and drain. Repeat until the drained water is clear.
3. Refill: Close the radiator drain cock. Slowly add the correct Mopar OAT coolant (50/50 mix) to the radiator until it's full. Fill the coolant reservoir to the "COLD FILL" line.
4. Bleed: Start the engine and let it run with the heater on high. As the engine warms up, the thermostat will open, and the coolant level in the radiator may drop. Continue adding coolant to the radiator as needed until it stabilizes. Keep the radiator cap off during this process. Some Ram 1500 models may have a small bleed screw located on a hose or the thermostat housing; if present, open it slightly to release trapped air until a steady stream of coolant emerges, then close it. Squeeze the upper and lower radiator hoses several times to help dislodge air bubbles.
5. Monitor: Install the radiator cap. Drive the vehicle and monitor the coolant level in the reservoir over the next few days, topping it off as necessary. An elevated front end (using ramps) can help make the radiator the highest point in the system, aiding in air removal.

Common Cooling System Issues for this Generation (2013-2018 Ram 1500)

Owners of the 2013-2018 Ram 1500 often report specific cooling system concerns. Being aware of these can help with early detection and prevention.

• Water Pump Failure: The water pump is a common failure point, especially on higher mileage vehicles. Symptoms include coolant leaks from the weep hole, whining noises, and overheating.
• Thermostat Issues: A faulty thermostat can lead to the engine running too hot or too cold. Symptoms include erratic temperature gauge readings, slow warm-up, or overheating.
• Radiator Leaks: Over time, the plastic end tanks of the radiator can become brittle and crack, leading to coolant leaks. Damage from road debris can also cause leaks.
• Heater Core Clogging: Issues with the heater core can result in a lack of heat in the cabin, often due to coolant contamination or incorrect coolant type causing corrosion.
• Coolant Reservoir/Hose Leaks: Cracks in the plastic coolant reservoir or deteriorating hoses can lead to small, persistent leaks.
