Subaru BRZ A/C Receiver Drier & Desiccant Guide (2013-2020)
Keep your BRZ's air conditioning blowing cold by understanding this critical, often-overlooked part.
- The A/C receiver drier (desiccant element) must be replaced any time the A/C system is opened for repair.
- For the BRZ, this part is a desiccant bag that fits inside the condenser; you do not need to replace the entire condenser.
- Quality aftermarket brands like Four Seasons are a cost-effective and reliable choice for this part.
- Proper A/C service, including evacuation and recharge by a professional or with the correct tools, is required for this job.
Is Your BRZ's A/C Not as Cold as It Used to Be?
If the air conditioning in your Subaru BRZ isn't performing well, a failing A/C receiver drier could be part of the problem. This component is a filter and a moisture trap for the A/C system. While it doesn't fail on its own often, it's a mandatory replacement part any time the A/C system is opened for service, like when replacing a compressor or a leaking hose. Exposing the old drier to the atmosphere for even a few hours can saturate it with moisture, making it useless.
Symptoms of a Bad A/C Receiver Drier
A bad receiver drier can cause several issues. Because its job is to absorb moisture, a saturated or failed drier can lead to poor A/C performance. Here are the most common signs:
- Reduced Cooling: This is the most frequent symptom. A clogged drier restricts refrigerant flow, meaning the air from your vents won't be as cold.
- Moldy Smell: If the desiccant fails, moisture can build up in the system, leading to mold or mildew growth and a bad odor from the vents.
- Foggy Windows: An A/C system that can't properly dehumidify the air may struggle to clear foggy windows.
- Visible Leaks: While rare for the drier itself, you might see oily residue near A/C line connections if the seals have failed.
Pro Tip: When to Replace
The rule for A/C work is simple: if the system is opened to the air, you must replace the receiver drier/desiccant element. This is required to protect your new parts and is often necessary to validate the warranty on a new A/C compressor. Many experts recommend replacing it every two years as preventative maintenance, though most owners replace it only during a larger A/C repair.
Choosing an Aftermarket Drier for Your BRZ
For the 2013-2020 Subaru BRZ, the A/C desiccant element is a serviceable part located inside the condenser. You don't need to replace the entire condenser, just the small desiccant bag inside. 🎬 Watch this video to see how to replace the desiccant element. Aftermarket brands like Four Seasons and Global Parts (GPD) offer direct-fit replacements.
OEM vs. Aftermarket: For a simple part like a desiccant bag, there is little to no quality difference between OEM and a reputable aftermarket brand. The key is the desiccant material itself. Brands like Four Seasons are well-regarded in the industry and produce parts in certified facilities. Given the significant cost savings, a quality aftermarket desiccant element is a smart choice for this repair.
Brand Tiers:
- Four Seasons / GPD: Both are established aftermarket brands that provide reliable A/C components. For a desiccant bag, either brand is a suitable and cost-effective option. User reviews suggest Four Seasons is a trusted brand for A/C parts.
Important: Installation Note
The new desiccant element should be the very last part you install before sealing the A/C system. Do not open the new part's packaging until you are ready to install it and immediately close the system. This minimizes its exposure to humid air, which reduces its effectiveness.

Frequently Asked Questions
Do I need to replace my A/C drier if I'm just recharging my system?
No. If you are just adding a small amount of refrigerant to a sealed system, you do not need to replace the drier. The drier only needs replacement when the system has been opened to the atmosphere, such as for a part replacement.
Can I replace the BRZ's A/C desiccant element myself?
Yes, but it requires special tools. The A/C system must be professionally evacuated of all refrigerant before it can be opened. After replacing the part, the system must be put under a vacuum to remove air and moisture before being recharged with the precise amount of refrigerant and oil. While the part itself is easy to access on the condenser, the overall job is best for experienced DIYers with the right equipment 🎬 See a step-by-step guide on replacing a desiccant element or condenser. or a professional shop.
Are there any recalls for the 2013-2020 BRZ A/C system?
No specific recalls were found for the A/C receiver drier or desiccant element on the 2013-2020 Subaru BRZ. Searches of the NHTSA database did not show any relevant recalls for this specific component and vehicle range.
What is the difference between a receiver drier and an accumulator?
They perform similar functions but are used in different types of A/C systems. Your Subaru BRZ uses an expansion valve system, which requires a receiver drier (or in this case, a desiccant element) on the high-pressure side. Accumulators are used on the low-pressure side in systems with an orifice tube.
