Im working on a 2005 Kia Optima 2.7L I did a timing belt i had to take the heads off and have them done it's a interfernce motor and bent valve's, after i get it all back together i go to start it turns over fine but did'nt run, did'nt want to fire so i check for spark, No spark. so what do you think the coilpack went bad????

sounds like you need to replace the timing belt and possibly need to have the cylinder head repaired if it bent the valves, put the belt first and if it doesn't have compression then you'll need to have the head repaired

the worry is that the battery post is getting hot
that indicates a dead short ,probably at the starter motor terminal
the engine is classified as a interference engine so there will be bent valves from the broken belt
with the engine not turning over and you didn't mention any head work it is very possible that a valve is bent and jamming on the piston stopping it moving and that is overloading the starter and heating up the battery post
Looks like it is back to square one and do it again

I would change the belt and do a compression check before starting the engine. That will show any distorted valves.

Pull the door panel and find the cause, it can be a faulty lock motor or the linkage rod has come off due to a broken retainer clip.

its the one top of the head (after removing the valve door)

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.

that is an interference engine, so if it was running when it broke, chances are very good that the valves are bent, at least-in worst case situations, pistons can be damaged too, but I would have the head removed and have the valves redone-while off, the top of the engine can be checked out. Timing bests are supposed to be replaced every 60,000 miles.

hi are you putting the cross head screw driver in the here are the instructions and a picture to help you...hope this helps

if you have never done one take it to a shop because if you have the timing off a little you take a chance of bending valves then you would need a new head

look at the motor, the side with all the belts, all that stuff has to come off and more not to mention the cam gears have to be set just right. it's a headace for an experinced person.
