For a 2014 Jeep Grand Cherokee, use Mopar Antifreeze/Coolant Type 2 HOAT, typically sold as a 50/50 premixed solution. This OEM coolant is designed for Jeep’s aluminum cooling system and the engines used in that year.
In more detail, the Grand Cherokee offered several engines in 2014 and all generally require a compatible HOAT coolant that meets Chrysler/Jeep specifications. If Mopar is unavailable, you can choose a high-quality HOAT coolant that explicitly states compatibility with Chrysler/Jeep engines and the 2014 Grand Cherokee. Avoid Dex-Cool (GM) formulas or universal coolants that aren’t HOAT-compatible, as mixing incompatible chemistries can cause corrosion or cooling-system issues.
What coolant does Chrysler/Jeep recommend?
Chrysler/Jeep generally specifies Hybrid Organic Acid Technology (HOAT) antifreeze/coolant for many of its vehicles, including the Grand Cherokee from that era. The safest route is to use the OEM Mopar HOAT coolant (often sold as a 50/50 premixed solution). This helps protect aluminum components and the cooling system over the long term. If you must substitute, ensure the replacement is HOAT and clearly labeled as compatible with Chrysler/Jeep engines.
To shop confidently, keep these criteria in mind when selecting coolant for your 2014 Grand Cherokee.
Before using any coolant, verify that you will be using a HOAT formulation that is compatible with Chrysler/Jeep engines and that the product is intended for use in aluminum cooling systems. The information below helps you choose the right product.
- HOAT formulation (not Dex-Cool or OAT-only products).
- Designed for aluminum engine cooling systems.
- Available as 50/50 premixed or as concentrate to be diluted with distilled water.
- Label indicates compatibility with Chrysler/Jeep vehicles.
- OEM Mopar option is preferred for best fit and warranty considerations.
Following these criteria will help ensure you select a coolant that protects your cooling system and maintains proper engine temperatures.
How to replace or top off coolant
Replacing or topping off the coolant in a 2014 Grand Cherokee requires care to avoid burns or engine damage. Use a HOAT coolant that matches the vehicle’s specification, and follow proper steps to drain, flush if needed, and refill. If you’re not comfortable performing the task, a professional service can ensure the system is bled of air and filled to the correct level.
These are the general steps you would follow, with the understanding that you should consult your service manual or a technician for vehicle-specific instructions:
- Allow the engine to cool completely, then place the vehicle on a level surface and disconnect the battery if necessary for safety.
- Open the radiator drain plug and reservoir cap to drain the old coolant.
- If performing a flush, use a manufacturer-recommended radiator flush solution and follow the product instructions to rinse the system clean.
- Reinstall the drain plug and fill the system with the HOAT coolant (premixed 50/50 or concentrate diluted with distilled water according to the label).
- Start the engine and run to operating temperature, then check for leaks and bleed air from the cooling system as described in the owner’s manual.
Aftercare is important: dispose of old coolant properly and recheck the level after the engine cools to ensure the system is properly filled.
Where to buy and what to pay
You can purchase the recommended coolant at Jeep dealerships, automotive parts retailers, or online. The price for a bottle of HOAT coolant varies by brand and whether you buy premixed or concentrate; a premixed 50/50 container is often the most convenient option for most owners. If you’re considering an alternative brand, verify it explicitly lists compatibility with Chrysler/Jeep engines and HOAT chemistry.
Common questions about compatibility
Key concerns include whether the coolant is premixed and whether it is HOAT versus another chemistry. Always confirm that the product states compatibility with Chrysler/Jeep engines and the 2014 Grand Cherokee model. Do not mix coolant types unless the manufacturer specifies it’s safe to do so, and never use the wrong coolant in a closed cooling system, as this can affect cooling performance and warranty coverage.
Summary
For a 2014 Jeep Grand Cherokee, the recommended coolant is Mopar Antifreeze/Coolant Type 2 HOAT, typically available in a 50/50 premixed form. If that specific product isn’t available, choose a high-quality HOAT coolant that explicitly states compatibility with Chrysler/Jeep engines and aluminum cooling systems. Avoid Dex-Cool (GM) and universal coolants that are not HOAT-compatible. When in doubt, consult the owner’s manual or a dealership service department, and consider having a professional perform a coolant flush or replacement to ensure proper bleed and fill.
