The correct coolant for a 2012 Dodge Charger is a 50/50 premixed ethylene glycol-based coolant that meets Chrysler’s approved specification for that model year. In practice, this means using a Mopar Extended Life Antifreeze/Coolant or another OEM-approved coolant explicitly labeled as compatible with Chrysler/Dodge vehicles and that is silicate-free.
What the Charger requires
The Charger’s cooling system is designed for long-life coolant that protects against freezing, overheating, and corrosion. To avoid issues, you should use only coolant that is labeled as approved for Chrysler/Dodge/Mopar vehicles and do not mix coolant types. It is best to use premixed 50/50 coolant that’s ready to install.
How to confirm compatibility
Check the owner’s manual, the radiator cap sticker, or the coolant reservoir label for the exact specification. If in doubt, ask a dealer or a trusted mechanic to confirm that the coolant you buy meets Chrysler's specification for the 2012 Charger and that it is silicate-free.
What to buy
To help your selection, consider these commonly accepted options. Before you read the list, note that you should only use one type and avoid mixing different coolant formulations.
- Mopar Extended Life Antifreeze/Coolant, 50/50 premixed. This is the OEM option designed specifically for Chrysler/Dodge vehicles.
- OEM-approved coolant that explicitly states compatibility with Chrysler, Dodge, and Jeep vehicles and that meets the manufacturer’s specification for extended-life coolant (often HOAT/OAT, silicate-free).
- Universal coolant labeled as compatible with Chrysler/Jeep/Mopar vehicles that is silicate-free and suitable for use in modern engines (confirm it meets Chrysler spec before use).
Whichever you choose, ensure the bottle label specifies Chrysler/Dodge compatibility and that the coolant is premixed 50/50 or that you are prepared to mix with distilled water to achieve the recommended concentration as per the product instructions.
Maintenance tips
When topping off or replacing the coolant, do not mix with other coolant types unless the product instructions allow it. Always use distilled water if you need to dilute. After draining and refilling, run the engine and check for leaks, then recheck the level when cold. Most extended-life coolants are rated for about 5 years or 100,000 miles, but always follow the exact interval stated on the product label and in the owner's manual.
Common pitfalls to avoid
Avoid using coolant intended for older vehicles or that contains silicates if the Chrysler specification calls for an HOAT/OAT, silicate-free formula. Mixing different coolant families can cause gel formation and reduce cooling efficiency. If you’re unsure, have the system flushed and refilled with the correct specification rather than topping up with an incompatible product.
Summary
For a 2012 Dodge Charger, use a 50/50 premixed ethylene glycol-based coolant that is explicitly approved for Chrysler/Dodge vehicles. The safest path is Mopar Extended Life Coolant or an OEM-approved coolant that meets Chrysler’s specification. Always verify compatibility on the product label or manual, avoid mixing different formulations, and follow the maintenance intervals recommended by the manual.
