How much freon does a 2008 Dodge Avenger hold?

The 2008 Dodge Avenger uses R134a refrigerant (the modern replacement for the old Freon). The full A/C system capacity is about 28 ounces (roughly 0.8 kilograms). Exact charge can vary slightly by engine and model, so always verify with the factory specification for your car.


In more detail, Dodge offered the Avenger with a 2.4-liter four-cylinder engine and, in some configurations, a larger V6. Most service literature lists the total refrigerant capacity as the same ballpark for these engines, but minor differences can occur due to condenser size, line routing, or replacements. When servicing, use a proper gauge set and evacuate/charge to the correct specification.


Refrigerant type and capacity guidance


Before charging, it's important to confirm the exact figure for your specific vehicle. The following notes provide a general guide and practical steps to ensure safe, proper recharge.


What you need to know before charging the system:



  • Total system capacity is typically around 28 ounces (about 0.79–0.83 kg) of R134a for the 2008 Avenger’s A/C system.

  • R134a was the standard refrigerant for this model year, replacing R12; ensure you use the correct refrigerant type and oil specification (commonly PAG oil).

  • After opening or replacing A/C components, have the system evacuated and recharge to the specified capacity using manifold gauges.


Concluding notes: The 28-ounce figure is a general guideline. Check the vehicle’s service manual or under-hood A/C label for the precise capacity for your exact configuration.


Summary


The 2008 Dodge Avenger’s A/C system is designed to hold about 28 ounces of R134a refrigerant. While this estimate covers typical configurations, exact capacity can vary by engine variant and component changes. When in doubt, consult the official service documentation or have a professional perform the charge using correct gauges and procedures.

What coolant does a 2008 Dodge Avenger take?


The recommended coolant for a 2008 Dodge Avenger is a HOAT (Hybrid Organic Acid Technology) antifreeze/coolant that is either orange or yellow, typically a 50/50 mix with distilled water. It is crucial to use the correct type to prevent corrosion and provide freeze and boil-over protection. You can use either a concentrate that you mix yourself or a pre-mixed solution. 
Coolant specifications

  • Type: HOAT (Hybrid Organic Acid Technology)
  • Color: Orange or Yellow
  • Form: Either a 50/50 pre-mixed solution or a concentrate that you mix with distilled water.
  • Recommended brand: Prestone and Zerex are frequently mentioned as compatible brands. 

Important considerations
  • Mixing coolants: Avoid mixing different types of coolant. If you are unsure of the coolant currently in the system, it is best to do a full flush before adding new coolant. 
  • Pre-mixing: If using a concentrate, always mix it with high-quality distilled or deionized water to the desired ratio. Using tap water can lead to scale and corrosion. 
  • Checking the level: Check the coolant level in the reservoir when the engine is cold. Never open the radiator cap or reservoir cap when the engine is hot. 



How many ounces of R-134a do I need?


1.5 lbs. or 24 oz of R134A is what is required. Hand-turn the compressor 15-20 times after charging! Failure to do this may cause the reed valves to become damaged.
