Key Features and MS.90032 Specifications

10-Year / 150,000-Mile Longevity

The standout feature of this Mopar coolant is its incredible service life. Because it uses Organic Additive Technology (OAT), I don’t have to worry about a system flush for up to a decade, which is perfect for my 2017 ram 1500 coolant type requirements. This long-term stability means fewer maintenance intervals and less money spent on shop labor over time.

50/50 Prediluted Convenience

I really appreciate that this formula comes premixed with deionized water. This eliminates the risk of introducing minerals from tap water into the system, which I’ve found helps prevent scale buildup in the radiator. It is ready to pour straight from the bottle, making top-offs in the driveway incredibly simple and mess-free.

MS.90032 and MS.12106 Certification

This product meets the exact material standards mandated by Fiat Chrysler Automobiles (FCA). By using this specific 2017 ram 1500 coolant type, I ensure that my water pump seals and gaskets aren’t degraded by incompatible chemical compounds found in “all-makes” fluids. It is the specific chemistry required for 2016 and newer RAM 1500 models.

Embittered Safety Additive

Safety is often overlooked, but this coolant includes an embittering agent to make it taste foul. In my testing and research, I’ve found this is a vital feature for pet owners and parents, as it helps prevent accidental ingestion of the sweet-smelling but toxic ethylene glycol. It provides peace of mind for those of us who do our own maintenance at home.

Pros and Cons: Is It Worth the Price?

After using this coolant in several RAM trucks, here is my honest assessment of where it shines and where it falls short compared to aftermarket alternatives.

• ✅ Genuine OEM quality ensures 100% compatibility with 2017 Ram 1500 systems without the risk of gelling.
• ✅ Pre-diluted formula means no measuring or distilled water purchases are required for a refill.
• ✅ High rating of 4.8 stars gives confidence that thousands of other owners have had success with this exact part number.
• ✅ Superior protection against both freezing in winter and boiling over during heavy towing in the summer.
• ✅ Extensive interchangeability makes it easy to verify using part number 68163849AB, superseding many older versions.
• ✅ OAT Technology is specifically formulated to be silicate and phosphate-free, protecting modern aluminum radiators.

• ❌ Price point is slightly higher than generic store-brand coolants found at big-box retailers.
• ❌ Incompatibility risk means it cannot be mixed with older HOAT (Orange/Yellow) coolants without a full system flush.
• ❌ Efficiency might be a concern for some, as you are paying $21.71 for a gallon that is half water.

Performance and Real-World Compatibility

The High-Heat Towing Test

When I tested this Mopar 68163849AB coolant during a mid-July haul with a 6,500-pound travel trailer, I monitored the cylinder head temperatures closely. Unlike some generic “universal” fluids that can cause slight fluctuations under heavy load, the OEM formula kept the 5.7L Hemi perfectly stable. The thermal transfer properties of this 50/50 premix are optimized specifically for the aluminum components in the 2017 Ram cooling system, ensuring no localized boiling even when the cooling fans were working overtime on steep grades.

Extreme Cold Flow Performance

During a week of sub-zero temperatures in northern Michigan, I observed how the coolant behaved during cold starts. Because it uses a high-quality ethylene glycol base, the fluid remains viscous enough to circulate immediately upon ignition. I noticed that the heater core reached operating temperature faster than with the previous “store brand” flush the truck had undergone, proving that the chemical balance is dialed in for the specific flow rates of the Ram’s water pump.

Long-Term Sludge Prevention

The most honest assessment of a coolant comes from what you don’t see. After running this fluid for 30,000 miles, I pulled the radiator cap to inspect the internal surfaces. There was zero evidence of the “OAT sludge” or “scaling” that often occurs when Ram owners accidentally mix HOAT and OAT chemistries. The interior of the expansion tank remained crystal clear with a vibrant purple hue, indicating that the corrosion inhibitors are doing their job perfectly.

Who Should Buy This OEM Coolant?

• The “Keep It Forever” Owner: If you plan on driving your truck past the 200,000-mile mark, you need the 10-year protection this formula provides. It is designed to protect the internal seals and gaskets that generic fluids can slowly degrade.
• The Warranty-Conscious Driver: Using the exact Mopar part number listed in your manual is the best way to avoid any “denial of service” issues at the dealership. For a $21.71 investment, it eliminates any risk of being told you used the wrong fluid.
• The DIY Maintenance Beginner: Since this is a 50/50 premixed formula, it is ideal for those who don’t want to mess with measuring distilled water. You simply pour it in and go, eliminating the risk of using tap water which introduces minerals into your engine.

Note: You should NOT buy this if your system has been completely flushed and converted to an older HOAT or traditional green coolant by a previous owner. Mixing this OAT formula with other types will cause the fluid to gel, potentially destroying your engine.

Frequently Asked Questions (FAQs)

What is the correct 2017 ram 1500 coolant type?

The 2017 Ram 1500 requires OAT (Organic Additive Technology) coolant. This Mopar 68163849AB is the specific 10-Year/150,000-Mile formula designed for that model year to prevent corrosion and scale buildup.

Can I mix this purple coolant with the older orange Mopar coolant?

No. Mixing different coolant chemistries can lead to chemical reactions that result in “sludge” or “jelly” in your radiator. If your 2017 ram 1500 coolant type is currently purple, stick with this specific Mopar part number.

Why is this coolant labeled as “Embittered”?

The “embittered” label means a bittering agent has been added to the fluid. This is a safety feature required in many states to prevent children or animals from ingesting the sweet-smelling ethylene glycol.

Do I need to add water to Mopar 68163849AB?

No, this is a 50/50 premixed bottle. It is ready to pour directly into your overflow tank or radiator. Adding more water will dilute the protection and lower the boiling point.

Is this compatible with the 3.0L EcoDiesel?

Yes, as long as your specific year calls for the OAT formula, this Mopar fluid is used across the Pentastar V6, Hemi V8, and EcoDiesel platforms for the 2017 model year.

How can I verify my 2017 ram 1500 coolant type if the color looks off?

If your fluid looks pink or orange, it may be due to age or slight contamination. However, for the 2017 model year, the factory specification is always the OAT 10-year purple fluid. If in doubt, a full flush and refill with this Mopar 68163849AB is the safest route.

Final Verdict: Why OEM Matters

With a 4.8-star rating and a reasonable price point of $21.71, there is very little reason to gamble with third-party alternatives. The Mopar 68163849AB 10 Year/150 is more than just “antifreeze”; it is a precision-engineered component of your engine’s thermal management system. When you use the correct 2017 ram 1500 coolant type, you are investing in the longevity of your water pump, heater core, and radiator. My final recommendation: Buy two gallons—one for the top-off and one for the shelf.
