The cold faucet is leaking, and I am trying to repair it by replacing the valve cartridge. However, for the love of god, I can't find a way to open the faucet so that I can replace the valve cartridge. I don't see a small opening anywhere and I can't seem to remove any top or tip of the faucet. I tried to unscrew the handle, but I am stuck afterwards. Any help would be much appreciated.
Give Kohler a call. All their products carry a lifetime warranty or at least they used to, They can explain the procedure you are looking for and send you the repair parts free to you.
Usually on kohler you unscrew the pedestal. On cold put a cloth around the pedestal use pliers turning counterclockwise.
