The correct coolant for a 2017 Jeep Cherokee is a HOAT (Hybrid Organic Acid Technology) antifreeze/coolant formulated for FCA US LLC vehicles—specifically Mopar Antifreeze/Coolant 5-Year/100,000 Mile Formula—or an equivalent HOAT coolant that explicitly states compatibility with Chrysler/Jeep products.
For the KL-generation Cherokee, using the right type of coolant matters for corrosion protection and long-term reliability. The vehicle’s cooling system is designed around FCA’s HOAT chemistry, and using a non-approved formula such as GM Dex-Cool or a universal coolant that isn’t FCA-certified can lead to improper cooling and potential damage. Always verify the label and consult the owner's manual or a dealer if you’re unsure.
Recommended coolant options
Before selecting a coolant, it helps to know which formulations are acceptable for this model. The options below cover the official Mopar recommendation and compatible general guidance.
- Mopar Antifreeze/Coolant 5-Year/100,000 Mile Formula (HOAT) — the factory-recommended coolant for FCA US LLC vehicles, ethylene glycol-based and designed for long-life service.
- Any HOAT coolant labeled as compatible with FCA US LLC vehicles and meeting Chrysler/Jeep specifications — look for explicit compatibility with FCA brands on the label or product description.
- Avoid using Dex-Cool (GM) or universal green/greenish formulations unless the product explicitly states FCA/Chrysler compatibility—mixing incompatible coolants can cause corrosion or seal damage.
When in doubt, choose the Mopar option or a verified FCA-compatible HOAT from a reputable brand and confirm the product meets the Chrysler/Jeep specification on the label.
How to refill or top up the coolant
If you’re planning a DIY top-up or a full coolant replacement, follow these general steps to minimize risk and ensure proper cooling-system function. Always refer to the owner’s manual for model-specific steps and safety precautions.
- Park on a level surface and let the engine cool completely before opening the cooling system to avoid scalding.
- Locate the coolant reservoir and radiator fill neck, and check the current level against the markings.
- Use a premixed 50/50 HOAT coolant (or mix the concentrate per the product instructions) that is FCA-compatible, rather than plain water alone.
- Slowly top up the system until the level reaches the full line, being careful not to overfill.
- Start the engine and run it to operating temperature, then turn on heat to help bleed air from the system. Check for leaks and listen for abnormal sounds.
- After the engine cools again, recheck the level and top off if necessary. Dispose of any drained coolant at a proper recycling facility.
Following these steps helps ensure the system is filled correctly and reduces the likelihood of air pockets or overheating after a service.
Where to find official specifications and guidance
The most reliable source is the vehicle’s owner’s manual and the under-hood label, which specify the exact coolant type and mix. You can also confirm compatibility with FCA-approved products by consulting a Jeep dealership, authorized service center, or Mopar’s official documentation.
Summary
For a 2017 Jeep Cherokee, use a HOAT antifreeze/coolant formulated for FCA US LLC vehicles, with Mopar Antifreeze/Coolant 5-Year/100,000 Mile Formula as the primary option. If choosing a third-party coolant, ensure it is explicitly compatible with Chrysler/Jeep vehicles. Avoid Dex-Cool or non-FCA-approved formulas. When performing a refill or replacement, follow standard safety steps and consult the manual or a dealer if you are uncertain.
