Kia Clock Spring w/ Heated Wheel 93490-3R325: 2026 OEM Specs
What a clock spring does
A clock spring, also called a spiral cable, maintains electrical continuity between the fixed steering column and the rotating steering wheel. Depending on vehicle equipment, its circuits may serve the driver airbag, horn, steering-wheel audio or cruise controls, and heated-wheel wiring. It is not a universal electrical ribbon: connector count, steering-wheel options and centering position must match the vehicle.
Fitment and package checks
Use the VIN, model year, trim and steering-wheel equipment to verify fitment. A non-heated clock spring or a visually similar Kia part can have different circuits. Compare the OE number, connector keying, mounting tabs and steering-angle sensor provision. Ask whether the unit is supplied centered or requires a specified centering procedure, and confirm whether the package includes a retaining pin or other shipping lock.
| Check | Confirm | Reason |
|---|---|---|
| Vehicle | 2014–2016 Cadenza or Optima; exact trim and VIN | Year and equipment changes affect connectors and steering controls. |
| OE reference | 93490-3R325 and any supersession noted by Kia | Prevents mixing similar spiral-cable part numbers. |
| Wheel option | Heated steering wheel present and connector matches | Missing or incorrect circuits can disable the heater or create faults. |
| Airbag connector | Color, lock and terminal layout match the original | Airbag circuits require exact compatibility. |
| Centering | Shipping lock and neutral position instructions | Over-rotation can tear the ribbon after installation. |
Review the 93490-3R325 heated-wheel clock spring listing and, for comparison only, the 93490-1R420 Hyundai Accent clock spring. They are different applications. Use the request-for-quote page or support@koeep.com if your VIN or OE number does not match.
Symptoms of a failed or mis-centered clock spring
- Airbag warning lamp after steering-wheel movement or a stored restraint-system code.
- Horn, audio, cruise or steering-wheel buttons stop working while other cabin functions remain normal.
- Heated-wheel function is unavailable on an equipped vehicle.
- A clicking, rubbing or binding sound appears as the wheel is turned.
- Intermittent faults that change when the wheel is rotated can point to a ribbon or connector issue.
Replacement workflow and safety
Follow the Kia service manual for the exact Cadenza or Optima. Park with the wheels straight, record radio or vehicle settings as needed, disconnect the negative battery cable and wait the specified time before touching the airbag module. Never probe an airbag connector with a test light or meter unless the service information explicitly allows that test.
- Keep the steering wheel centered and secure it so the column cannot rotate during disassembly.
- Remove the airbag module using the vehicle-specific release points, then disconnect connectors by their locks.
- Mark connector routing and remove the steering wheel without pulling on the wiring.
- Compare the old and new clock springs, including center position, tabs, connector keys and heated-wheel terminals.
- Install the replacement without rotating it past its permitted travel. Reconnect every circuit and reinstall the wheel at the original alignment marks.
- Reconnect the battery, scan for restraint and steering-angle faults, and complete any required steering-angle calibration before driving.
Post-installation checks
With the vehicle stationary, verify the horn, audio/cruise buttons, heated wheel and steering-wheel illumination if equipped. Turn the wheel slowly from lock to lock while listening for rubbing and confirming that no harness is pulled. Check the airbag lamp self-test and scan for current or stored codes. If the steering wheel is off-center, do not compensate by rotating the clock spring; correct the wheel alignment and centering procedure.

Frequently asked questions
Does 93490-3R325 fit every 2014–2016 Kia?
No. The live listing names Cadenza and Optima with a heated steering wheel. Verify VIN, trim, market and connector layout before ordering.
Can I use a non-heated clock spring?
Not as a direct assumption. A non-heated unit may lack the terminals or circuit paths required by the heated wheel and may set faults.
Why is centering important?
The ribbon has a limited travel range. Installing it off-center can cause the ribbon to reach its stop and tear when the wheel turns.
Will a new clock spring clear the airbag light?
Only if the clock spring caused the fault and the system passes its self-test. Read and clear codes with a suitable scan tool after the repair.
Should I disconnect the battery first?
Yes. Follow the factory wait time and airbag handling procedure. Never work on the module with the battery connected or probe its terminals.
What if the horn works but the buttons do not?
Check each circuit separately. A partial failure can involve a switch, connector, fuse, clock-spring circuit or control module rather than the entire assembly.
Confirm the correct safety-system part
Send KOEEP your VIN, model year, trim, heated-wheel status, OE number and a photo of the connectors. We can help confirm the application before you open the airbag system.
