Agreed with davy, the motor is usually help on with 3 or 4 bolts. you will need to remove the wiper arms before you can remove the scuttle panel. Then it should be a block connector and a few bolts to remove.
Did you fit the timing belt or a garage?? If a garage did it, then take it back to them as it will be their fault. if you did it, strip the timing covers back and make sure everything lines up properly. I dont know much about these kia's yet as i only bought mine last week, but if it has a timing sensor fitted and its in the wrong place it will be hard to start and run the engine which will do more damage than good.
