The 2013 Dodge Charger uses a HOAT coolant—Hybrid Organic Acid Technology—based on ethylene glycol. The recommended choice is Mopar HOAT Extended-Life coolant or an equivalent that meets FCA specifications, in a 50/50 premixed formulation or a concentrate that you mix with distilled water according to the label.
Understanding the coolant type for the 2013 Charger
Chrysler, Dodge, and other FCA vehicles from this era rely on a specific category of coolant designed to protect aluminum engines and cooling systems. HOAT coolants are designed to provide extended service life while remaining compatible with the materials used in FCA engines.
What HOAT means for your vehicle
HOAT stands for Hybrid Organic Acid Technology. It blends organic acids with conventional inhibitors to create a coolant that lasts longer than traditional inorganic formulas while remaining compatible with the engine’s metal surfaces and seals. For FCA vehicles, using a HOAT formulation that meets the manufacturer’s specifications helps prevent corrosion and overheating issues.
- Ethylene glycol–based formulation
- Typically green in color, though color can vary by brand
- Designed for extended-life service when labeled as such
- Must be compatible with Chrysler/Dodge/Mopar specifications
- Not compatible with non-HOAT or GM Dex-Cool-type formulations without verification
Using an FCA-approved HOAT coolant ensures proper protection for the engine and cooling system, reduces the risk of corrosion, and supports the vehicle’s intended maintenance intervals.
Choosing the right coolant for your Charger
When selecting coolant, you should confirm compatibility with Chrysler/Fiat specifications and opt for a product that clearly states HOAT and FCA compatibility. If you’re unsure, consult your owner’s manual or contact a dealer for the exact spec.
The following considerations guide a correct choice
- Look for a HOAT designation on the label and ensure it explicitly notes Chrysler/ FCA compatibility
- Prefer a long-life formulation (often marketed as 5-year/100,000-mile or similar) if your dealer or manual recommends it
- Choose 50/50 premixed coolant if you want convenience; or buy the concentrate and mix with distilled water per directions
- Avoid mixing with non-HOAT or different technology (e.g., Dex-Cool or standard inorganic coolants) without guidance
- Consider OEM-branded Mopar coolant or reputable aftermarket HOAT formulations that meet FCA specifications
Following these guidelines helps ensure optimal protection for the radiator, water pump, heater core, and engine block while maintaining the recommended service intervals.
Maintenance and service tips for coolant in a 2013 Charger
Regular maintenance helps prevent overheating and corrosion. Here are practical steps to manage your coolant lifecycle.
- Check the reservoir level when the engine is cold and before a road trip; add the correct HOAT coolant if low
- Use the same coolant type when topping up; avoid mixing different coolant technologies
- If flushing or replacing, drain the system, flush with distilled water if advised, then refill with the recommended HOAT coolant
- Fill to the proper level, reinstall the radiator cap, and run the engine to operating temperature with the radiator cap loosened briefly to purge air
- Inspect for leaks, check hoses, and recheck the level after the engine cools
For major coolant service, many owners choose to have the work done by a professional to ensure complete flushing and proper bleeding of air from the system.
Where to buy and how to verify compatibility
Your best bet is to confirm the exact FCA specification in the owner's manual or by contacting a Dodge/Chrysler service center. If you buy aftermarket HOAT coolant, ensure it clearly states FCA/Chrysler compatibility and HOAT formulation.
Practical tips for purchasing
- Prefer a 50/50 premixed HOAT coolant labeled for FCA or Chrysler vehicles
- If buying concentrate, mix with distilled water as directed and do not exceed the recommended concentration
- Keep receipts and records of coolant type and service dates for maintenance history
Verification steps after purchase help prevent compatibility issues and ensure you’re using the correct product for the 2013 Charger’s cooling system.
Summary
For a 2013 Dodge Charger, use a HOAT (Hybrid Organic Acid Technology) ethylene glycol–based coolant that is compatible with FCA Chrysler specifications. Mopar HOAT Extended-Life coolant is the standard OEM choice, but equivalent HOAT formulations that meet Chrysler/Fiat standards are acceptable. Use 50/50 premixed coolant or mix concentrates with distilled water as directed, and follow the vehicle’s maintenance schedule to keep the cooling system in good condition. When in doubt, consult the owner’s manual or a Dodge dealership to confirm the exact specification for your engine variant.
