How much freon does a 2007 Dodge Charger hold?
The 2007 Dodge Charger uses R-134a refrigerant, and the full system charge is typically in the range of 28–32 ounces, depending on the engine and AC hardware. For the precise amount, check the under-hood label or the official service manual.
What refrigerant does it use?
Freon is a brand-name term historically associated with refrigerants like R-12. In 2007 Chargers, the air conditioning system runs on R-134a. Some newer vehicles use R-1234yf, but this model year uses R-134a. Do not mix refrigerants or oils, and ensure you use the correct type and amount for your car’s system.
Estimated capacity and how to verify
Because the Charger was offered with different engines and A/C configurations, the total refrigerant charge can vary slightly. A practical snapshot is provided below, but precise figures should be confirmed on the vehicle’s data label or in the service manual.
- Approximate total refrigerant charge: 28–32 ounces of R-134a.
Note: The refrigerant charge refers to the refrigerant itself only. The system also requires a lubricant (PAG oil) in a separate quantity, typically around 4 ounces, with the exact amount depending on service procedures and components replaced. Always evacuate the old refrigerant before recharging and perform a vacuum test to remove moisture.
Finding the exact specification for your car
To obtain the exact charge for your specific vehicle, use one or more of the following methods:
- Check the under-hood refrigerant capacity label on the AC lines or near the radiator support.
- Consult the vehicle’s owner's manual or Chrysler/Dodge service data for your engine option (e.g., 3.5L V6 vs. 5.7L Hemi).
- Ask a qualified technician or your dealer for the precise specification, especially if major AC components have been replaced.
Incorrect charging can reduce cooling performance or damage the compressor. Use proper recovery equipment and follow the recommended procedures.
Why capacity might vary after repairs
Replacing major components such as the compressor, evaporator, receiver/drier, or changing the hose routing can alter the system’s capacity and lubrication needs. After such work, always verify the correct refrigerant and oil amounts with the service data and perform a full leak test and vacuum before recharging.
Operational tips and safety
When recharging the system, keep these guidelines in mind:
- Use the correct refrigerant type (R-134a) and the appropriate PAG oil quantity as specified for your vehicle.
- Connect gauges to the low- and high-pressure sides following the recharge kit instructions.
- Recover any existing refrigerant and evacuate the system to a deep vacuum before adding new refrigerant.
- Ensure there are no leaks, and do not overcharge the system, as overcharging can raise pressures and damage components.
- Consider having the service performed by a licensed technician if you are not equipped to do it safely.
These steps help protect the system and maintain cooling performance while staying compliant with environmental regulations.
Summary
A 2007 Dodge Charger typically holds about 28–32 ounces of R-134a refrigerant in its full A/C system, with exact figures varying by engine and configuration. Verify the precise amount on the factory data label or in the service manual, and account for a separate oil charge when recharging. Proper evacuation, leak testing, and adherence to the recommended refrigerant type are essential for reliable cooling.
