The 2020 Jeep Cherokee uses a long-life HOAT coolant that’s ethylene glycol–based, typically supplied as Mopar Genuine Antifreeze/Coolant 50/50 Premixed.
Understanding the requirement
In practice, Jeep’s owner’s manual and service guidance focus on a compatible long-life HOAT coolant. The recommended fill is Mopar 50/50 premixed coolant, or an equivalent HOAT coolant that explicitly meets Chrysler/Jeep specifications. Avoid using coolant types not approved for FCA engines, and avoid mixing different coolant chemistries without a full system flush.
Coolant options for the 2020 Cherokee
Below are commonly accepted options that align with FCA/Jeep guidelines. The goal is to maintain proper corrosion protection and cooling performance for the engine’s aluminum components.
- Mopar Genuine Antifreeze/Coolant 50/50 Premixed; HOAT, ethylene glycol–based, designed for long life (typically 5 years/100,000 miles).
- Compatible third‑party HOAT coolant that explicitly meets Chrysler/Jeep Mopar specification (the current standard used by FCA); ensure it is ethylene glycol–based.
- Any HOAT coolant labeled as compatible with FCA/Jeep engines and referencing the appropriate Mopar/Chrysler specification on the bottle or product sheet.
Note: Do not mix coolant types. If you’re switching brands or chemistries, perform a complete cooling-system flush to prevent additive incompatibilities.
Maintenance and replacement tips
Maintaining the cooling system is key to preventing overheating and corrosion. Jeep’s guidance generally supports using a long-life HOAT coolant and following the service intervals in the owner’s manual. If in doubt, consult a dealer or a qualified technician to confirm the exact specification for your vehicle’s VIN and production date.
- Verify the coolant label to ensure you’re using a premixed 50/50 solution, not a concentrate.
- When adding coolant, wait for the engine to cool and use distilled water if you dilute or top off; never use tap water due to minerals.
- Do not mix different coolant chemistries; if changing formulas, perform a full system flush before refilling.
- Check the reservoir and hoses for signs of leaks or contamination and reseal the cap properly after topping off.
Concluding note: If you’re unsure about the correct specification for your exact Jeep Cherokee, verify with the owner’s manual or contact a Jeep/Chrysler service professional to avoid misfueling or incompatibilities.
Summary
The 2020 Jeep Cherokee uses a long-life HOAT coolant, preferably Mopar 50/50 premixed. If Mopar isn’t available, choose a HOAT coolant that explicitly meets Chrysler/Jeep specifications. Do not mix coolant types, and follow the vehicle’s service intervals and guidelines in the owner’s manual. Regular checks and proper flushing practices help maintain cooling performance and engine longevity.
