Kia Optima A/C Receiver Drier and Desiccant Guide (2011-2020)
Keep your Optima's A/C blowing cold by understanding this critical, but often overlooked, part.
- The A/C receiver drier MUST be replaced whenever the A/C system is opened for any repair.
- Replacement is not a DIY job; it requires specialized equipment to safely evacuate and recharge the refrigerant.
- Symptoms of failure include poor cooling, musty smells, and in serious cases, frost on A/C lines.
- For this part, proper installation procedure is more critical than the minor differences between aftermarket brands.
Is Your Optima's A/C Not as Cold as It Used to Be?
A weak A/C in your Kia Optima can be caused by many things, but a failing A/C receiver drier is a common culprit, especially on older models within the 2011-2020 year range. Since this part's job is to absorb moisture, it has a limited lifespan and eventually becomes saturated, just like a sponge that can't hold any more water. When this happens, it can't protect your A/C system anymore, leading to poor performance and potential damage.
Pro-Tip: Replace it Whenever the System is Opened
Experienced mechanics agree: you must replace the receiver drier anytime the A/C system is opened for a repair. This includes jobs like replacing a compressor or condenser. Most warranties for new A/C compressors require a new drier to be installed at the same time. Failing to do so can void the warranty and lead to the quick failure of your new parts.
Symptoms of a Failing A/C Receiver Drier
A bad receiver drier can cause several issues. Here’s what to look out for:
- Poor Cooling Performance: The most common symptom is an A/C that doesn't blow as cold as it once did. This can happen if the drier is clogged, restricting refrigerant flow.
- Musty or Moldy Smell: If the desiccant is saturated and can no longer absorb moisture, mold and mildew can grow in the A/C system, causing a bad smell from your vents.
- Foggy Windows You Can't Clear: If the A/C can't effectively remove moisture from the cabin air, you may have trouble defrosting or defogging your windows.
- Visible Frost on A/C Parts: A severe blockage in the drier can cause a rapid pressure drop, leading to frost or ice forming on the drier itself or connected A/C lines.
- Rattling Noises: If the desiccant bag inside the drier breaks apart, you might hear rattling sounds. This is serious, as the desiccant beads can travel through the system and cause a major blockage.
Choosing the Right Aftermarket Drier for Your Optima
For the 2011-2020 Kia Optima, the A/C drier is often a small desiccant bag or cartridge that fits inside a chamber on the A/C condenser. 🎬 Watch how to replace a car AC desiccant receiver drier. This is different from older canister-style driers. When shopping for a replacement, you'll find several aftermarket options.
Brand Tiers: What to Expect
Tier 1: OEM (Original Equipment Manufacturer)
The original Kia part (Part Number: 97802-17000) is the benchmark for fit and quality. It's designed specifically for your Optima. However, it is the most expensive option.
Tier 2: Aftermarket Brands (Four Seasons, Global Parts/GPD)
Brands like Four Seasons and Global Parts (GPD) are popular aftermarket choices. They provide a cost-effective alternative to OEM parts. User reviews on these brands are mixed, which is common for aftermarket A/C components. Some users report years of good service, while others experience issues. Four Seasons is a widely recognized brand, but some consider their non-compressor parts to be of lower quality. GPD is another common alternative. For a simple part like a desiccant bag, the primary concern is correct fitment and fresh, dry desiccant. Given the low cost of the part itself, the priority should be on proper installation procedure rather than minor brand differences.
Important Note on Fitment: The A/C system in the Kia Optima changed over its 2011-2020 lifespan, with different engines (2.4L, 2.0L Turbo, Hybrid) potentially using different components. Always verify the part fits your specific year and sub-model before ordering.
Cost to Replace a Kia Optima A/C Receiver Drier
The cost is heavily weighted towards labor, as the A/C system must be professionally evacuated and recharged.

Frequently Asked Questions (FAQ)
Can I replace the A/C receiver drier myself?
This is not recommended for a DIYer without the proper equipment. Replacing the drier requires the A/C system's refrigerant to be recovered with a special machine. After replacement, the system must be put under a deep vacuum to boil off any moisture before being precisely recharged with refrigerant. Failure to do this correctly will result in poor performance and can damage the system. This job is best left to a qualified shop.
🎬 See the process for replacing an AC receiver drier bag.Are there any recalls for the 2011-2020 Optima A/C system?
Searches did not find any recalls or Technical Service Bulletins (TSBs) specifically for the A/C receiver drier. However, several recalls were issued for the 2010-2015 Optima and 2011-2013 Optima Hybrid related to risks of engine compartment fires from other components, such as the ABS module. There was also an emissions service campaign for 2011-2015 models related to the evaporative canister, which is a different part.
How often should the receiver drier be replaced?
It should be replaced any time the A/C system is opened for service. If your system has never been serviced, some experts recommend replacing it as a preventive measure every three to four years, though most owners wait until a repair is needed.
Does my Optima have a receiver drier or an accumulator?
The 2011-2020 Kia Optima uses a thermal expansion valve system, which means it is equipped with a receiver drier (or desiccant element). Accumulators are used on systems with an orifice tube.
