The quickest answer: use a Mopar Antifreeze/Coolant Type 2 (OAT) or any OEM‑approved long‑life coolant labeled as Chrysler/Jeep Type 2, typically sold premixed 50/50. Do not mix different coolant types.
In detail, the 2017 Dodge Journey relies on a modern organic-acid long-life coolant designed for aluminum engine components. Use a 50/50 mix of coolant and distilled water unless the product instructions specify otherwise. Always consult the owner’s manual or a certified technician to confirm the exact specification for your vehicle’s engine variant and regional market. Below is guidance on compatibility, selection, and maintenance.
OEM compatibility and how to choose
To ensure proper protection and compatibility with the Journey’s cooling system, select coolant that explicitly meets Chrysler/Jeep Type 2 OAT (organic acid technology) requirements. The options below reflect common, validated choices when labeled accordingly.
- Mopar Antifreeze/Coolant Type 2 (OAT) – the OEM option guaranteed to meet Chrysler/Jeep requirements.
- Any reputable aftermarket long-life coolant that explicitly states it meets Chrysler/Jeep Type 2 (OAT) specification and is safe for aluminum engines.
- Premixed 50/50 coolant that is labeled as Type 2/OAT compatible to simplify mixing and determine correct dilution.
Conclusion: For best compatibility and warranty alignment, choose an OEM Type 2/OAT coolant (Mopar or an aftermarket product that explicitly lists Chrysler/Jeep Type 2 compatibility). Avoid green, silicate-bearing conventional formulas and avoid mixing incompatible coolant types.
Maintenance and service intervals
Modern long-life coolants are generally designed for longer service intervals, but always verify the interval in the owner’s manual or with a dealer. Typical guidance is around 5 years or 150,000 miles, whichever comes first, though regional guidelines or engine variant could adjust this. When refilling, use a 50/50 mix unless the label specifies otherwise, and use distilled water if you’re mixing concentrates. Never open the radiator cap or pressure cap while the engine is hot.
DIY flushing and refilling: a concise guide
If you need to flush or replace the coolant yourself, follow these careful steps to minimize risk to the cooling system.
- Allow the engine to cool completely before opening any caps or drains.
- Place a drain pan under the radiator and drain the old coolant according to the service manual.
- Flush the system with distilled water or a reputable radiator flush product per the product directions.
- Refill with a 50/50 premixed OEM-approved coolant labeled Type 2/OAT, or mix concentrates following the product’s instructions.
- Check for leaks, bleed air if your model requires a bleed procedure, and top off to the expansion tank as needed.
Note: Proper disposal of used coolant is important—take it to a recycling facility or automotive shop that accepts spent antifreeze.
Summary: The right coolant for a 2017 Dodge Journey is an OEM-approved long-life coolant (Type 2/OAT) compatible with Chrysler/Jeep specifications. Use a premixed 50/50 solution when possible, avoid mixing incompatible coolants, and follow the maintenance intervals and bleeding procedures outlined in the owner’s manual or by a dealer.
