Step-by-Step Instructions
Follow these steps carefully
1
Open glovebox and twist the tabs
The 2016–2020 Optima (JF) cabin filter is behind the glovebox. You'll need: a new cabin filter; no tools required. Open and empty the glovebox. Inside you'll see tabs — TWIST them COUNTERCLOCKWISE to unlock. Then unhook the damper on the right; the box swings down.
🔧 Mechanic's note — Tom Becker
I've learned: the twist tabs are the Optima's whole personality on this job — counterclockwise to unlock, clockwise to lock. People who've done ten other Kias reach for the push-stoppers that aren't there and crack the tabs. Twist, don't push.
2
Locate the filter cover
With the glovebox swung down, look behind it for the cabin air filter cover — it has a tab on the right side. That's the filter door you'll remove next.
3
Remove the filter cover
Remove the cover by squeezing the tab on its right side and pulling it off (or pinch the tabs together to unclip). Set it aside — the filter is now visible.
4
Remove the old filter
Pull the old filter straight out and note the airflow direction. A dirty filter is what's hurting the Optima's climate control. The JF Optima's filter is a standard panel.
5
Install the new filter
Slide the new filter in, matching the airflow direction, and seat it fully. Reinstall the cover by lining it up and pushing until it clicks into place.
6
Reassemble and test
Swing the glovebox back up, reattach the damper on the right, and twist the tabs CLOCKWISE to lock them. Close the glovebox and test the climate control. Replace every 15,000–20,000 miles.
All Done!
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
⚠️ Common Mistakes to Avoid
- • Forgetting to disconnect the glove box damper, leading to potential damage during removal.
- • Installing the new filter with the airflow direction reversed, reducing its effectiveness.
- • Not properly securing the glove box after replacement, causing rattling or improper closure.
