Owners of other Kia and Hyundai vehicles with similar windshield wipers such as the Forte, Cadenza, Rio, Soul, Sedona, Sorento, Sportage, Sonata, Accent, Elantra, Veloster, Azera, Tucson, Santa Fe and Genesis may also find these DIY instructions to be helpful.

Replacement windshield wiper blades with their sizes in inches are as follows: Driver Side 24" and Passenger Side 18".

A few compatible replacement windshield wiper blades with their part numbers are as follows: Bosch 24A & Bosch 18A, Rain-X 5079280-1 & Rain-X 5079275-1, Anco 31-24 & Anco 31-18, Michelin 8524 & Michelin 8518, and Trico 25-240 & Trico 25-180.

No tools are needed to replace the windshield wiper blades.

Then rotate the old wiper blade at a slight angle away from the metal wiper arm to expose the release button on the mounting bracket.

Press in the small black plastic release tab on the wiper blade mounting bracket towards the metal wiper arm.

Slide the old wiper blade down and off the metal hook at the end of the wiper arm.

Place a towel on the windshield to protect it from cracking or chipping just in case the metal wiper arm smacks down on to the glass.

I recommend buying the Bosch 24A and Bosch 18A wiper blades since they have excellent reviews on Amazon.

Line up the metal wiper arm with the hole in the center of the new wiper blade.

Slide the new wiper blade up and slide the mounting bracket in to the metal hook at the end of the wiper arm until it clicks securely in to place.

Double check that the new wiper blade is properly installed before gently lowering it down to the windshield.

For the best results, it would be a good idea to thoroughly clean the windshield and apply a glass treatment product such as Rain-X.
