SOURCE: 2004 KIA Optima LX timing belt/water pump

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

SOURCE: 2005 Kia Amanti; heater on driver side blowing cold

For those of you who may google this link and are looking for an solution, my local repair shop isolated my 2005 Amanti problem to a $2.78 plastic clip on the temperature blend door actuator rod linkage. It simply fatigued and eventually broke resulting in the actuator rod falling off the actuator door lever. The labor to isolate the problem and to replace the clip did amount to almost $170. Hope this helps those of you in the future.

Change your crankshaft sensor located behind lower timing belt cover. The way I check it is to unplug the maf and see if it will start if so stop the engine and do a diagnostic 3 DTC's should come up on screen ,one would be the crankshaft sensor. This should be done by a experienced tech.

SOURCE: 2005 Kia Sportage. A/C blows but does not blow

the A/C system can have many problems first check at the compressor. look to see if when the air is on that the clutch on the compressor is spinning. if it is not try adding some refrigerant to the low side inlet. i would use the kind with the dye in it. if the system is completely empty you may need to put two cans in just to get the compressor to kick on. if you have two cans in and the compressor clutch is not spinning then you compressor is shot and will need to be replaced. if it is spinning it should be blowing cold. look for leaks in the lines leaks will be identified by the dye glowing usually green if no leaks are found you may have just lost refrigerant from normal usage. if that is the case add another can to top it off and enjoy. hope this helps '

My 2005 kia optima LX ran out of gas and now it won't start, put gas and new battery but still won't start . please help

Paul is on the right ball - it sounds like fuel - turn over the engine with the pipe disconnected until the fuel comes through - if you don't succeed, consult a reputable shop - you need someone that knows what they are talking about to physically look at the car to solve the problem - this will save you a lot of time and expense. ?

2005 optima ckankshaft sensor

2005 optima cranksensor if you are a 2.4 the CKP sensor is located at front of crankshaft,behind the timing belt cover. If your engine is running rough or stalling try shaking the sensor connector to see if it affects engine operation. Inspect the male to female terminal for proper fit. If you are a 2.7 the CKP sensor is mounted on left side of engine block, near the fly wheel. For either engine size if you are cranking the engine and your tach reads zero,you are dealing with a failed CKP.
