Jeep generally recommends Mopar Antifreeze/Coolant Extended Life Formula in a 50/50 premixed solution, or any coolant that meets Chrysler/Jeep specifications and is compatible with aluminum engines. The exact requirement can vary by model year and engine, so always check your owner’s manual or ask a Jeep dealer for your specific vehicle.
Jeep's official guidance
Current Jeep guidance emphasizes using a high-quality ethylene glycol–based coolant designed for aluminum engines. For most modern Jeep models, Mopar Extended Life Antifreeze/Coolant is the default factory-recommended option. However, exact specifications can differ by year and engine, so verify the specification for your vehicle before purchasing.
The following options are commonly accepted by Jeep service literature and retailers as compatible with Jeep engines.
- Mopar Antifreeze/Coolant Extended Life Formula (50/50 premixed) — Jeep’s factory-recommended coolant for many contemporary models.
- Any commercially available coolant that explicitly carries Chrysler/Jeep specifications and is labeled as suitable for aluminum engines and long-life service.
When in doubt, consult your owner's manual or a dealership to confirm the exact specification required for your model-year and engine configuration.
Mixing and maintenance guidelines
To keep the cooling system in good condition, follow these guidelines when topping up or replacing coolant.
The following guidelines help you avoid common pitfalls and ensure proper performance:
- Do not mix coolant types (for example, HOAT and OAT) or brands unless the manufacturer confirms compatibility.
- If you switch coolant brands or types, perform a complete cooling-system flush to prevent sediment and precipitates from forming.
- Use a 50/50 mix only if you are starting with a concentrate; if using premixed coolant, you already have the correct ratio.
- If diluting concentrate, use distilled water rather than tap water to minimize minerals and corrosion risk.
Adhering to these guidelines helps prevent corrosion, deposits, and overheating, preserving engine and cooling-system longevity.
Finding the right coolant for your model
Because Jeep’s cooling systems and recommended coolants can vary by year and engine, the most reliable source is your owner’s manual or a Jeep service advisor. If you choose an aftermarket coolant, ensure the product packaging clearly states that it meets Chrysler/Jeep specifications and is suitable for aluminum engines and long-life service.
Summary
In short, Jeep’s recommended approach centers on Mopar Extended Life Antifreeze/Coolant (50/50 premixed) or any coolant that meets Chrysler/Jeep specifications and is compatible with aluminum engines. Always verify the exact specification for your model-year and engine, avoid mixing incompatible coolant types, and follow proper dilution procedures. For the most accurate guidance, consult your owner’s manual or a Jeep dealer.
