2017 Ram ProMaster Coolant Capacity & Type

The 2017 Ram ProMaster holds approximately 10.6 to 12.0 quarts (10.0 to 11.4 liters) of coolant, depending on the engine.

Quick Answer

• Total Cooling System Capacity: 10.6 - 12.0 quarts (10.0 - 11.4 liters)
• OEM Coolant Spec: Mopar Antifreeze/Engine Coolant 10 Year/150,000 Mile Formula OAT (Organic Additive Technology) in an Amber/Pink color. It meets FCA Material Standard MS-90032.
• Mix Ratio: Typically 50/50 pre-mixed coolant, or 50/50 concentrate mixed with distilled water.

Capacity by Engine Option

The 2017 Ram ProMaster was offered with two engine options, each having a slightly different coolant capacity:

Flush Interval

Maintaining your coolant is crucial for the longevity of your engine. The recommended flush interval for the 2017 Ram ProMaster is:

• Normal Duty: 10 years or 150,000 miles, whichever comes first.
• Severe Duty: If your ProMaster operates under heavy loads, in extreme temperatures, or with frequent towing, it's wise to consider changing the coolant more frequently, possibly around 5 years or 75,000 miles.

How to Refill & Bleed

Properly refilling and bleeding the cooling system is essential to prevent air pockets, which can lead to overheating. Here's a general procedure for your 2017 Ram ProMaster:

1. Safety First: Ensure the engine is completely cool before starting. Wear appropriate safety gear, including gloves and eye protection.
2. Drain the System: Loosen the radiator drain cock (petcock) located at the bottom of the radiator to drain the old coolant into a suitable container. For a more complete drain, you may also need to remove a lower radiator hose.
3. Flush (Optional but Recommended): If performing a full flush, close the drain cock, refill with distilled water, run the engine with the heater on until it reaches operating temperature, then drain. Repeat until the water runs clear. Do NOT use tap water for flushing or mixing, as minerals can cause deposits.
4. Refill with New Coolant: Close the drain cock. Slowly add the correct Mopar OAT coolant (50/50 mix) to the radiator until full. Fill the coolant reservoir to the "MAX" line.
5. Bleed the System: This is a critical step. The 3.6L Pentastar engine often has a bleeder screw near the thermostat housing or on a cooling hose for easier air removal. Open this screw while filling to allow air to escape. For both engines:
   • Start the engine with the radiator cap off (or loosely placed) and the heater on full blast.
   • Allow the engine to warm up, watching for bubbles to escape from the radiator filler neck. Squeeze the upper and lower radiator hoses repeatedly to help dislodge air pockets.
   • Maintain the coolant level by adding more as needed.
   • Once the thermostat opens and the fans cycle, install the radiator cap.
6. Final Check: Drive the vehicle, monitoring the temperature gauge. After the engine cools down, recheck the coolant level in the reservoir and top off if necessary.

Common Cooling System Issues for this Generation

Owners of 2017 Ram ProMaster vans, particularly those with the 3.6L Pentastar engine, may encounter some cooling system issues typical for this generation:

• Thermostat Housing Leaks: The plastic thermostat housing can be prone to cracking and leaking over time. This is a relatively common issue that can lead to coolant loss.
• Oil Cooler/Filter Housing Leaks (3.6L Pentastar): While not strictly a "cooling system" part, an oil cooler/filter housing leak can cause coolant and oil to mix, leading to distinct issues. It's something to be aware of if you notice unusual fluid mixing or repeated coolant loss without an obvious external leak.
• Water Pump Leaks: Like any vehicle, the water pump can eventually wear out and develop leaks, often indicated by coolant weeping from the weep hole on the pump or a noticeable drop in coolant levels.
• Radiator Hose Degradation: Over time, radiator hoses can become brittle, crack, or soften, leading to leaks. Regular inspection is recommended.

Regular maintenance and using the correct OEM-specified OAT coolant are key to preventing these issues and ensuring your ProMaster's cooling system operates efficiently.
