Scion FR-S 2013-2016 A/C Receiver Drier & Desiccant Element Guide
Keeping your FR-S air conditioning blowing ice cold starts with understanding this critical, often-overlooked part.
- The A/C desiccant element MUST be replaced every time the A/C system is opened for service.
- Failure to replace the desiccant bag after a repair can cause catastrophic failure of the new A/C compressor.
- The job requires professional equipment to evacuate and recharge the refrigerant; it is not a simple DIY task.
- For this part, affordable aftermarket brands like Four Seasons or Global Parts are a perfectly acceptable choice.
Symptoms of a Bad A/C Desiccant Element
The desiccant element itself doesn't have moving parts, so it doesn't "fail" in a way that throws a check engine light. Its failure is about becoming saturated with moisture. This happens over time or anytime the A/C system is opened for a repair. A saturated desiccant bag can no longer protect your system, leading to several problems.
- Poor A/C Performance: If your A/C isn't as cold as it used to be, it could be a sign of moisture in the system affecting the refrigerant's ability to cool.
- Foggy Windows You Can't Defrost: An A/C system with too much moisture won't effectively dehumidify the air, making it hard to clear up interior window fog.
- A/C System Failure After a Repair: If you've recently had a component like the compressor or a hose replaced but didn't change the desiccant bag, the leftover moisture can quickly ruin the new parts. This is the most common reason for replacing it.
Mandatory Replacement Item
You should replace the A/C desiccant element every time the A/C system is opened to the atmosphere. This includes repairs like replacing the compressor, condenser, or any A/C lines. Failure to do so will likely void the warranty on the new parts and can lead to premature failure of the entire system.
Choosing the Right Aftermarket Desiccant Element
For the 2013-2016 Scion FR-S, the original desiccant bag is serviced separately from the condenser. Aftermarket replacements are readily available and are a cost-effective choice, as they perform a simple but essential function. There is little difference in performance between a new OEM bag and a new aftermarket bag, as long as it is installed correctly in a properly serviced A/C system.
Available Brands: Four Seasons & Global Parts
Both Four Seasons and Global Parts Distributors (GPD) are well-known aftermarket brands for A/C components. For a part like a desiccant bag, which is a maintenance item designed to be replaced, either brand offers a reliable and affordable option. The key is not the brand of the bag, but the fact that it is new and installed quickly to prevent it from absorbing moisture from the outside air before the system is sealed and vacuumed.
Installation Pro-Tip
The desiccant bag is located inside the condenser. Access involves removing a plug on the side of the condenser, pulling out the old bag with pliers, and inserting the new one. The A/C system MUST be professionally evacuated of all refrigerant before you open the system and recharged after the new bag is installed. This is not a task that can be done with a simple DIY refrigerant can from an auto parts store.
Cost to Replace the A/C Desiccant Element
Replacement cost is mostly labor. The part itself is inexpensive, but the job requires an A/C service machine to recover and recharge the refrigerant. It's typically done at the same time as a larger repair.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Desiccant Element | $13 - $23 |
| Shop Labor (A/C Evacuate & Recharge) | $150 - $300 |
| Total Estimated Cost | $163 - $323 |
Frequently Asked Questions (FAQ)
Do I need to replace the desiccant bag if my A/C is still cold?
No. The desiccant bag is not a typical maintenance item unless the A/C system is opened for another repair. If your A/C is working fine, leave it alone. The only exception is if a leak has been present for a long time, allowing moisture to enter the system.
Can I replace the A/C desiccant bag myself?
While removing the bag itself is simple, the process requires specialized equipment to safely recover the refrigerant from the system before opening it and to pull a vacuum and recharge it afterward. For this reason, it is considered a job for a professional shop or a highly experienced DIYer with the right tools.
Is there a recall on the A/C system for the 2013-2016 Scion FR-S?
No, there are no specific recalls for the A/C receiver drier or desiccant element on the 2013-2016 Scion FR-S. There was a recall for engine valve springs on 2013 models, which required the A/C system to be disconnected for the repair. An improper A/C service after this recall could potentially lead to issues.
What's the difference between a receiver/drier and a desiccant element?
A receiver/drier is a self-contained metal canister, while a desiccant element is just the bag of moisture-absorbing beads itself, which is placed inside a component like the condenser. Your Scion FR-S uses the desiccant element style.
