Re: altenator belt breaking
Is this a single serpentine belt system or a V belt with 2 or more belts running the accessories? There is an alignment issue, another bad accessorie or bad bearing (quite possibley the new alt) or as mentioned a bad idler ( if a serpentine belt setup)

The KIA Optima uses a 12 volt charging system with an alternating generator and a frame-grounded starting battery. The alternator is a smaller unit with an internal voltage regulator. The bushings, windings and regulator may wear out and fail, requiring replacement. The average backyard mechanic can change the alternator in a KIA in about an hour. Things You'll Need 1.Socket set 2.Floor jack 3.Lug wrench 4.Screwdrivers 5.Crowbar Instructions: 1.Disconnect the battery's positive terminal bolt by turning it counterclockwise. Set it away from the terminal. 2.Jack up the Optima and remove the front passenger side wheel by turning the lug nuts counterclockwise using the lug wrench. Set the wheel and tire aside. 3.Remove or fold aside the wheel well cover by turning the small screws counterclockwise and gently pulling it from the retainer clips. This will give access to the engine. 4.Push on the belt tension pulley until the belt loosens, then pull the belt off of the alternator's pulley wheel. The belt can be left hanging in place. 5.Turn the alternator's bolts in a counterclockwise direction using the socket wrench. A smaller wrench head may be required for the tight space. 6.Pull the alternator free by wiggling it out of the mount. 7.Position the new alternator into the mount and secure the bolts that hold it in place. 8.Push on the belt tension pulley to give enough slack to wrap the belt around the alternator's pulley wheel. 9.Restore the wheel well cover by pushing it onto the clips and securing the screws. 10.Replace the wheel by tightening the lug nuts in a clockwise direction, alternating the pressure of opposing bolts. This sets the wheel better than tightening all of the nuts in a circle. 11.Lower the Optima onto the ground, and reconnect the battery.
On smaller engines the timing belt should be checked regularly.When the belt breaks the camshaft stops turning and valves stay open at wrong time but the pistons keep moving and come up to top of cyclender and crash into the valves causing the first bit of damage.What I think happen to cause it to break again prematurly was somthing was still bent from first time causing resistance on belt which caused belt to break second time.These engines cant take that kind of abuse once never mind twice.I dont think second belt was installed wrong to cause this.Like I said the mechanic missed somthing bent or damaged the first time.But unfourtunatly this will be hard to prove.Unless you requested and still have old parts from first time work was done and can prove that it was mechanic neglegants.Good Luck.
It seems the starter is playing up.First check if your battery is charged fully or try to jump start and see what happens.If the engine start then it's either you need a new battery or else you need a replacement alternator.Test using a voltmeter if the actual altenator is working.Finally the last option is the starter motor that needs changing or fixing...Hope this helps.
The thing is your doing the timing belt the water pump is right their with it . it should cost you much more at all besides the cost of the water pump. When doing a timing belt I have a rule that I go by The timing belt/seals =cam , crank , any pulley & tensioner & water pump all get replaced at the same time. I did a t-belt on a Audi A-8 very complex whole front of car has to come off as well, he didnt want to do w-pump & thermostat his thermostat was their as well not even a month later the water pump gave out he had to pay double the price because he didnt want to do it when I had it apart the first time. And make sure mechanic is ase certified . good luck
the problem is not the altenator. you should have a idler pully and a self adjusting idler tensioner. if thes e go bad the bearings tend to seize up and break belts i would check these first chance you get the tensioner should be spring like and be hard to move back and forth the pulley part of it should spin freely with out makeing a noise. please rate this
