All nuts and bolts are left hand turns.. IE anticlockwise
If there are any threads exposed, compare them to a regulat bolt and nut. Follow the angle of the threads and position the bolt in your hand so the threads are similiar. Turn your nut, there is your answer. lefty loosey righty tighty

Unhook your battery. Reach behind the fan shroud on the right side of the car with a 17mm wrench and feel around until you find the top nut. Try to take it off. If it doesn't come off, keep this in mind. Jack up the car, put jackstands under it, put yourself under it and unhook the battery cable and bendix wire. If you got the top nut completely off, remove the bottom nut, then slip the starter out of the car. If it DIDN'T come off, clamp a set of vise-grips to the bolt at the top of the starter, then crawl out, remove the top nut, crawl back under, remove the bottom nut and take the starter out. If you had to do the vise-grips thing, take the top bolt to a machinist to have a 1/4" bolt welded sideways to the head of the starter bolt. In operation, the bolt welded sideways will hit the transmission case the first time you try tightening the nut to it, it will turn no further, and you can tighten it right up.
Remember "righty tighty, lefty loosy" :) or to the right it tightens the screw to the left it loosens it up.

To tighten the starter shaft nut, first ensure the engine is turned off and cooled down. Use the appropriate socket or wrench to securely grip the nut, and turn it clockwise to tighten. It's important to apply even pressure to avoid stripping the threads. If available, consult the manufacturer's specifications for the correct torque setting to ensure it's tightened properly.
you have to hold the battery cable or the nut behind it to keep it from turning with the nut you are removing.
Weld a larger nut to what is left of the broken bolt, let it cool then turn it out.
To remove the hub nut from a Kia, you typically turn it counterclockwise (lefty-loosey). It's important to ensure that the vehicle is securely supported and that you use the appropriate tools to avoid damaging the nut or surrounding components. Always consult the specific vehicle's service manual for any additional details or torque specifications.
Assuming the starter is now removed and what remains of the broken bolt is in the bell housing, weld a slightly larger nut over the broken bolt, let it cool completely then turn it out.
Sounds like starter selenoid or the starter cable going to the stsrter needs to be taken off and cleaned and the inner nut on the selenoid may not be torqued properly.
Check the starter solenoid first, followed by the starter. The starter is either not getting power from the solenoid or the starter itself is bad.
