Acura CSX A/C Receiver Drier Replacement Guide (2006-2011)
If your CSX air conditioning is weak, the small receiver drier might be the reason.
- The receiver drier is a desiccant bag inside the condenser on a 2006-2011 CSX.
- It MUST be replaced every time the A/C system is opened for service.
- Replacement is not a DIY job; it requires special equipment to handle refrigerant.
- Before major repairs, check the simple A/C compressor clutch relay first.
Is Your A/C Not Blowing Cold?
When the A/C in your 2006-2011 Acura CSX stops blowing cold, a common cause is a loss of refrigerant. However, the parts that keep the refrigerant clean and dry are just as important. The A/C receiver drier is a key maintenance part. It's designed to absorb moisture and filter debris from the A/C system. Once it becomes saturated with moisture or clogged with debris, it can't do its job, leading to poor cooling and potential damage to other A/C components.
Pro Tip: Check the Easy Stuff First
On the Acura CSX and the mechanically identical Honda Civic, a very common A/C problem is a faulty compressor clutch relay. This is an inexpensive part located in the under-hood fuse box. If your A/C compressor isn't engaging at all, it's worth checking this relay before assuming a more serious problem.
When to Replace the Receiver Drier
The rule for replacing the receiver drier is simple: it must be replaced any time the A/C system is opened. This includes when you replace a compressor, condenser, evaporator, or any A/C hose. The desiccant material inside the drier becomes saturated with moisture within hours of being exposed to outside air, making it useless. Most warranties for new A/C compressors require that you also install a new receiver drier.
Choosing the Right Aftermarket Drier
Since the Acura CSX is based on the Honda Civic, parts are widely available. For a maintenance item like the receiver drier desiccant bag, you don't necessarily need to buy the OEM part. Aftermarket brands offer a cost-effective and reliable alternative.
- Mahle: Often an original equipment manufacturer for many car brands, Mahle parts are known for high quality and are a solid choice if available.
- Four Seasons: A major aftermarket supplier with a long history. They produce parts in certified facilities and are a common, reliable choice for A/C components.
- Global Parts (GPD): Another large aftermarket distributor offering a wide range of A/C parts.
For this specific part, any of these brands will perform the necessary function. Since it's a simple desiccant bag, the brand choice is less critical than for a complex part like the compressor itself. The most important thing is that a new one is installed whenever the system is serviced.

Frequently Asked Questions
Can I replace the A/C receiver drier myself?
This is not recommended for a DIY project unless you are an experienced technician with the proper tools. Replacing the drier requires recovering the refrigerant from the system, which must be done with a special machine to avoid releasing it into the atmosphere and to prevent injury. The system must then be put under a vacuum to remove all air and moisture before being recharged with the precise amount of refrigerant and oil. For these reasons, this job is best left to a professional mechanic.
Where is the receiver drier located on my CSX?
On the 2006-2011 Acura CSX, the receiver drier is a desiccant bag located inside a cylinder that is part of the A/C condenser assembly. The condenser is situated in front of the radiator at the front of the engine bay.
Is there a recall for the A/C system on my CSX?
No, there are no recalls or technical service bulletins (TSBs) related to the A/C receiver drier or the A/C system for the 2006-2011 Acura CSX.
What's the difference between a receiver/drier and an accumulator?
They perform similar functions but are used in different types of A/C systems. Your CSX uses an expansion valve system, which requires a receiver/drier on the high-pressure side. Systems with an orifice tube use an accumulator on the low-pressure side to protect the compressor. You will only have one or the other.
