Your 2014 Jeep Patriot uses Dex-Cool extended-life coolant in the HOAT category, typically Mopar Extended Life or any Dex-Cool–compatible HOAT formulation. It should be used in a 50/50 mix with distilled water, whether you buy premixed coolant or concentrate you dilute yourself.
In more detail, the Patriot’s cooling system is designed around a Dex-Cool–type coolant engineered for Chrysler/Jeep engines. Using the correct coolant helps prevent gelling, corrosion, and overheating. Always verify the exact specification in your owner’s manual or with a dealer if you’re unsure.
Identifying the right coolant for your Patriot
To help you choose the correct product, review these core options and compatibility notes.
- Mopar Antifreeze/Coolant Extended Life (HOAT) — typically labeled Dex-Cool, orange, and intended for Chrysler/Jeep engines. This is the OEM-recommended option for many modern FCA vehicles.
- Other reputable Dex-Cool–compatible HOAT coolants — look for labels that state compatibility with Chrysler/Jeep vehicles and Dex-Cool or HOAT formulations.
- Mixing guidance — if you buy concentrate, mix it to a 50/50 ratio with distilled water unless the product specifies a different final ratio for your vehicle.
- Avoid non–Dex-Cool or universal green/blue coolants unless the label explicitly says they’re Dex-Cool compatible with Chrysler/Jeep engines.
Conclusion: For best results, use Mopar Extended Life or another Dex-Cool–compatible HOAT coolant and maintain a 50/50 mixture with distilled water, per the product label and your owner's manual.
Mixing and maintenance guidelines
Before performing coolant maintenance, note these guidelines to ensure proper mixing and system care.
- Premixed coolant is convenient and typically ready to use; concentrate requires accurate dilution with distilled water.
- Do not mix Dex-Cool with green, yellow, or other non–Dex-Cool coolants unless the product explicitly states it is compatible.
- Always aim for a 50/50 final mix unless the coolant label specifies a different ratio for your engine.
- When in doubt, rely on Mopar OEM coolant products or Dex-Cool–compatible HOAT formulations and follow the manual’s instructions.
After completing a coolant change or flush, check for leaks, verify the level when cold, and top off to the correct mark. Proper disposal of old coolant is essential and should follow local environmental regulations.
Maintenance steps for coolant service (general guide)
If you’re flushing or replacing coolant, here is a typical sequence to follow. Always refer to the owner’s manual for exact steps and torque specs.
- Ensure the engine is completely cold before starting work.
- Place the vehicle on a level surface and disconnect the battery if needed for safety.
- Drain the old coolant from the radiator and engine block following the vehicle’s service procedure.
- Install a radiator flush if you’re flushing the system, then drain thoroughly again.
- Refill with the correct Dex-Cool–compatible HOAT coolant, mixed to 50/50 with distilled water unless the product specifies otherwise.
- Bleed the cooling system to remove air pockets as described in the manual; start the engine and run to operating temperature with the radiator cap off to purge air.
- Check for leaks, recheck the coolant level when the engine is cold, and top off as needed.
Following these steps helps ensure proper cooling system function and longevity. If you’re unsure about the procedure, have a qualified technician perform the service.
Summary
For a 2014 Jeep Patriot, use Dex-Cool extended-life HOAT coolant—Mopar Extended Life or another Dex-Cool–compatible formulation—mixed 50/50 with distilled water. Avoid mixing with non–Dex-Cool or universal coolants unless explicitly labeled compatible. Always consult the owner’s manual or a dealership for exact specifications and service intervals, and dispose of old coolant responsibly.
