Compatible Models

We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model
  • Kia Amanti, Borrego, Cadenza, Forte, K5, Niro, Optima, Rio, Sedona, Sorento, Soul, Sportage, and Stinger applications only where VIN lookup specifies 31010-3L600U

Product Overview

A cracked seal, cap that no longer clicks, missing tether, or small EVAP leak code may come from the fuel cap after the filler neck and rest of the evaporative system are checked. This factory part restores the original cap design when the VIN calls for 31010-3L600U.

A new cap will not fix every check-engine light. Purge valves, vent valves, hoses, canisters, filler-neck damage, and wiring can create the same EVAP codes. Kia uses different caps across trims and markets, so verify the VIN and number rather than relying on model name alone.
