The 2018 Chrysler 300 uses pink, long-life HOAT antifreeze (Mopar) in a 50/50 premixed solution. Verify exact specification in your owner's manual or with a dealer before purchasing.
Color and coolant specification explained
For the 2018 Chrysler 300, the recommended coolant is a HOAT (Hybrid Organic Acid Technology) antifreeze, typically sold by Mopar as Long-Life Antifreeze/Coolant in pink. The factory fill is commonly a 50/50 premixed solution. Using the correct color and specification helps protect the cooling system from corrosion and overheating across driving conditions.
What to look for when shopping or topping up
Before you check your coolant supply or buy more, consider these guidelines to ensure compatibility and performance.
- Check the owner's manual for the exact coolant specification (Mopar Long-Life HOAT, pink, 50/50 premixed).
- Look for a label indicating Mopar Antifreeze/Coolant or Long-Life HOAT and confirm the pink color on the bottle.
- Avoid Dex-Cool (orange) or universal green/yellow formulations unless explicitly approved for your engine by Mopar—mixing different chemistries can cause issues.
- If topping up, use the same coolant type and premixed ratio; if you cannot, consult a dealer or qualified technician before mixing.
Following these steps helps maintain proper cooling system protection and prevents potential chemical incompatibilities.
Why the color alone isn’t the only guide
Color can be a useful quick check, but it isn’t a guarantee of compatibility. Always confirm the exact spec in the manual or with a dealer. The 2018 Chrysler 300’s coolant is pink HOAT, but variations can occur by engine type or regional requirements, so verify before purchase or top-ups.
Summary
In short, a 2018 Chrysler 300 takes pink, long-life HOAT antifreeze (Mopar), typically in a 50/50 premixed formulation. Always confirm the exact specification in the owner's manual and avoid mixing with incompatible coolants. When in doubt, consult a dealership or qualified technician to ensure you use the correct product.
