Dodge Durango 2005-2011 A/C Accumulator: A Complete Replacement Guide
If your Durango's A/C is blowing warm, the accumulator might be the problem—here's what you need to know before you buy a new one.
- The A/C accumulator must be replaced any time the A/C system is opened for another repair.
- Symptoms of failure include warm air, visible leaks, and rattling noises.
- Aftermarket brands like Spectra and Global Parts offer a cost-effective and reliable alternative to OEM.
- Replacement requires specialized tools to evacuate and recharge the system; it is not a simple bolt-on job for beginners.
Is Your Durango's A/C Accumulator Failing?
When the A/C accumulator in your 2005-2011 Dodge Durango starts to fail, the symptoms are often related to poor cooling performance. Because this part is designed to filter moisture and debris, it can become clogged or leak over time. Here are the most common signs of a bad A/C accumulator:
- Warm Air from Vents: This is the most frequent complaint. A clogged accumulator can restrict refrigerant flow, or a leak can lower the refrigerant level, both resulting in poor cooling.
- A/C Cools at High Speed, Warm at Idle: If your A/C gets a little cooler when you're driving on the highway but blows warm at a stoplight, it can be a sign of a low refrigerant charge, possibly from a leak in the system.
- Visible Refrigerant Leak: You might see a greasy or oily residue on the accumulator canister or on the ground beneath it. This is the refrigerant oil leaking out, which indicates the refrigerant gas is escaping, too.
- Rattling Sounds: If the internal components or the desiccant bag break apart, you may hear a rattling noise from the engine bay when the A/C is running.
No Recalls or TSBs Found
Our research found no specific recalls or technical service bulletins (TSBs) from Dodge or the NHTSA for A/C accumulator failure on the 2005-2011 Dodge Durango. This suggests there are no widespread factory defects for this part.
Choosing the Right Aftermarket A/C Accumulator
For a component like an A/C accumulator, an aftermarket part offers excellent value. The original Mopar part (OEM Part No. 5135919AA) can be costly, while aftermarket brands produce reliable replacements for a fraction of the price.
Common aftermarket brands available for your Durango include Spectra and Global Parts (GPD). Both are known for producing direct-fit parts that meet original equipment specifications. While some mechanics have preferences, for a standard replacement part like an accumulator, either brand is a suitable choice. The most important factor is that the part is new and installed correctly.
Always Replace, Never Reuse
The A/C accumulator must be replaced any time the A/C system is opened to the air (for example, when replacing a compressor or hose). The desiccant inside instantly absorbs moisture from the atmosphere, making it useless. Installing a used accumulator or leaving the old one in during a major repair will trap moisture and lead to premature failure of other, more expensive A/C components.
Cost to Replace a 2005-2011 Dodge Durango A/C Accumulator
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Part | $19 - $22 |
| New OEM Part | $40 - $170 |
| Shop Labor | $150 - $250 |
| Total Estimated Cost (Aftermarket) | $169 - $272 |
Cost estimates are for the part and labor for a standalone accumulator replacement, which includes evacuating and recharging the A/C system. Costs can vary by location and shop.
Frequently Asked Questions
Can I replace the A/C accumulator myself?
While unbolting the accumulator is simple, the full job is best for advanced DIYers with the right equipment. Replacing it requires recovering any existing refrigerant (which is illegal to vent), pulling a vacuum on the system to remove all air and moisture, and recharging it with the correct amount of refrigerant and oil. Without a vacuum pump and manifold gauges, the repair will fail.
Is an accumulator the same as a receiver/drier?
They perform the same function of removing moisture but are used in different types of A/C systems. Your Durango uses an orifice tube system, which is paired with an accumulator. Systems with an expansion valve use a receiver/drier. The terms are often used interchangeably, but they are not the same part.
Do I need to add oil when replacing the accumulator?
Yes. When you replace the accumulator, a specific amount of PAG oil is lost. You must add new PAG oil to the new accumulator before installation to ensure the A/C compressor stays lubricated. Check your Durango's service manual or the part manufacturer's instructions for the exact amount.
Will a new accumulator fix my A/C?
It depends on the problem. If your only issue is a leaking or clogged accumulator, then yes. However, the accumulator is often replaced because another part, like the A/C compressor, has failed. It's critical to diagnose the entire system to find the root cause of the problem before replacing parts.
