The 2017 Dodge Durango uses Mopar Extended Life Coolant (ELC) Type 2, a 50/50 premixed, silicate-free coolant approved by FCA for this model.
What the Durango's cooling system requires
The Durango’s engine environment relies on a long-life coolant that protects aluminum components and resists corrosion. The official specification for this vehicle is Mopar Antifreeze/Coolant Type 2 Extended Life Coolant, typically sold as a premixed 50/50 solution. Use only OEM Mopar coolant or another product that explicitly meets Chrysler’s Type 2 specification. Do not mix coolant types or brands unless the product label confirms compatibility with FCA Type 2.
Approved coolant options for topping up or replacing in the Durango include the following.
- Mopar Antifreeze/Coolant Type 2 Extended Life (ELC), 50/50 premixed, silicate-free coolant designed for FCA engines.
- Any coolant that explicitly lists Chrysler/Jeep Type 2 (or FCA Type 2) compatibility and is premixed 50/50, ensuring it is suitable for aluminum engine blocks.
In practice, most Durango owners stick with Mopar ELC Type 2 50/50 premixed to ensure full compatibility and service life.
Maintenance considerations
Keeping the cooling system in good shape involves regular checks and proper top-ups. The following guidelines help maintain optimal performance and prevent damage from overheating or corrosion.
To keep the Durango’s cooling system performing at its best, follow these routine steps.
- Check the coolant level when the engine is cold, and ensure it sits between the MIN and MAX marks on the reservoir.
- Top up only with the correct premixed coolant or with distilled water to restore a 50/50 mix if you’re using concentrate-based products; avoid tap water and incompatible formulations.
- Do not mix different coolant types or brands unless the label explicitly states compatibility with FCA Type 2.
- Replace the coolant at the intervals recommended by Chrysler, typically around every 5 years or 150,000 miles for Extended Life Coolant Type 2, or sooner if you notice overheating or coolant discoloration.
Proper maintenance helps prevent corrosion, overheating, and downstream cooling-system failures.
Summary
For a 2017 Dodge Durango, the recommended coolant is Mopar Extended Life Coolant Type 2, a 50/50 premixed, silicate-free solution. Use OEM Mopar coolant or any product that explicitly meets Chrysler Type 2 specifications, and follow the manufacturer’s service intervals. Always consult the owner’s manual or your dealer for the most precise guidance for your vehicle’s configuration.
